types of inflorescence with examples

Racemose Inflorescence: Inflorescence: Type # 2. Typical examples, are Cymose inflorescence. Share Your PPT File. In such cases, the arrangement of flowers is Centripetal, i.e., the oldest flowers towards the periphery and the youngest ones towards the Centre. b) spadix. In this inflorescence the main axis remains comparatively short and the lower flowers possess much longer stalks or pedicels than the upper ones so that all the flowers are brought more or less to the same level, e.g., in candytuft (Iberis amara). Racemose and Cymose Inflorescence | Botany, Inflorescence: Types and Special Types (With Diagram), Diversity in Modifications of Stems | Botany. L'inflorescence (du latin inflorescere : fleurir) est la disposition des fleurs sur la tige dune plante à fleur. Required fields are marked *. 2. When the main axis is branched in a corymbose manner and each branch has flowers arranged in corymbs, it is known as a compound corymb. Usually a whorl of leafy bracts is found at the base of branches and also at the bases of flowers arranged in umbellate way. A single insect may pollinate flowers in a short time without flying from one flower to another. The individual flowers (florets) are bracteate. The young flowers are either towards the periphery or scattered among the older flowers, as in Acacia, Albizzia. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate). The arrangement axis is termed an inflorescence. 3. It never terminates into a flower and bears flowers in acropetal (growing upward from the base or point of attachment) The main types of racemose inflorescence are: Raceme: The main elongated axis bears stalked flowers. This is also known as true cyme or compound dichasium. In this type of inflorescence the main axis (peduncle) branches repeatedly once or twice in racemose or cymose manner. In this type of inflorescence, you can see the peduncle modified in narrow cup-like structure. The table given below shows the differences between these two inflorescences. (iii) With the main axis flattened, i.e., capitulum or head. The whole inflorescence is enclosed by one thick boat-shaped spathe. What are the characters Mendel selected for his experiments on pea plant? Therefore, these are termed as special inflorescences. The oldest flowers develop in the centre and youngest towards the periphery of the disc, such arrangement is known as centrifugal. The two main types of inflorescence are racemose and cymose. (a) Racemose inflorescence. The flowers are arranged in groups or clusters, each of which is really a scorpioid cyme in which the main axis and the successive daughter axes have been reduced and the flowers are almost sessile. Racemose Inflorescence: In racemose inflorescence, the main axis continue to grow indifinitely until the last flower is formed at its apex. The first is Wood Forget-me-not and the second Russian Comfrey. 3) Hypanthium. Spikeletes are characteristic of Poaceae (Gramineae) or Grass family, e.g., grasses, wheat, barley, oats, sorghum, sugarcane, bamboo, etc. Typical examples of compound umbel are—Daucus carota (carrot), Foeniculum vulgare (fennel), Coriandrum sativum (coriander), etc. In this type of inflorescence, the main axis is unlimited in growth, branched or unbranched. The inflorescence may be Simple, Compound, Mixed, or Of Special Types. Content Guidelines 2. Examples: Cauliflower B2. Also known as spike of spikelets. The palea (also known as superior palea) often with two longitudinal ridges (keels or nerves), stands between the lemma and the rachilla. This is a modified spike with a long and drooping axis bearing unisexual flowers, e.g., mulberry (Moras alba), birch (Betula spp. Tetrapod: Classes, Characteristics, Examples, and Evolution, Phloem Transport Mechanism in Plants and Translocation, Cytoskeleton: Function, Structure, Chemical Composition, Types of Immunity in Immune System with functions and Disease, Malaria Disease: Historical Background, Types and Effects, Parts of Small intestine and their Functions. Others include: Cyathium Verticillaster Hypanthium What Is Racemose Inflorescence? Examples: Caesalpinia (peacock flower), Iberis amara (candytuft) Spadix in Anthurium . Flowers may occur singly, in groups, or in clusters. c) umbel. coconut. The flowers are small and are known as Florets. Inflorescence: Type # 1. (a) Scorpioid cyme: successive daughter axes develop on right and left alternately, forming a zigzag, as in Freesia. Racemose is a type of inflorescence in which the main … This type of opening of flowers is known as centrifugal. Cyathium 5. Angiosperm - Angiosperm - Inflorescences: Inflorescences are clusters of flowers on a branch or a system of branches. The whole branched structure remains covered by a single spathe. Generally the umbel is branched and is known as umbel of umbels (compound umbel), and the branches bear flowers, e.g., in coriander (Coriandrum sativum), fennel, carrot, etc. When a tadpole turns into a frog, its tail shrinks and is reabsorbed. The following points highlight the six major types of inflorescence. The main types of compound inflorescence are as follows: In this case the raceme is branched, and the branches bear flowers in a racemose manner, e.g., Delonix regia, Azadirachta indica, Clematis buchaniana, Cassia fistula, etc. The main axis ends in a reduced female flower which is tricarpellary and syncarpous pistil, borne on a long stalk. (With Methods)| Industrial Microbiology, How is Cheese Made Step by Step: Principles, Production and Process, Enzyme Production and Purification: Extraction & Separation Methods | Industrial Microbiology, Fermentation of Olives: Process, Control, Problems, Abnormalities and Developments. For example, the tomato may deliver simple individual flowers or inflorescences generally of the raceme or cyme types. Hypanthodium. The videos will have text , few examples and picture for students and teachers to get quick grasp of concept and supporting material to re-use. E.g Delphinium (Larkspur, Raphanus (Radish), Mustard. Each spikelet may bear one to several flowers (florets) attached to a central stalk known as rachilla. This is also a modification of spike inflorescence having a fleshy axis, which remains enclosed by one or more large, often brightly coloured bracts, the spathes, e.g., in members of Araceae, Musaceae and Palmaceae. Old flowers are at the base and younger flowers and buds are towards the apex. The young flowers are present in the center of the receptacle while the older ones toward the periphery. The involucre encloses a single female flower, represented by a pistil, in the centre, situated on a long stalk. The main axis may be elongated, shortened, or flattened into a Therefore the classification of Racemose Inflorescence is based on the Development of the main axis and pedicels of the flowers. The floral parts borne in the axil of lemma. Also known as head of heads or capitulum of capitula. In this inflorescence the primary axis remains comparatively short, and it bears at its tip a group of flowers which possess pedicels or stalks of more or less equal lengths so that the flowers are seen to spread out from a common point. A flower is present terminally on the main axis. it again possess various sub-types. 7. It may be branched or unbranched. Tn cymose inflorescence, the flowers develop in basipetal succession, i.e., the terminal flower is the oldest and … Ex: Callistemon. Cymose Inflorescence 3. The simple inflorescence is of two types according to its mode of branching. Your email address will not be published. The flower is surrounded at its base by an involucre. The flowers may be with stalked or sessile. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. This female flower remains surrounded by a number of male flowers arranged centrifugally. TOS4. The type of inflorescence is characteristic of Lamiaceae (Labiatae) family. c) of separate sexes. If we take a closer look at the cyme type, there can be simple cymes and dichotymously-branched cymes where the apex of the peduncle branches more or less equally into two. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. Inflorescence is the reproductive shoot, bearing a number of flowers. Types of Inflorescence 1. ), etc. Your email address will not be published. The oldest flower is in the centre and ends the main floral axis (peduncle). The type of inflorescence is characteristic of Lamiaceae (Labiatae) family. Each such branch bears a group of flowers in an umbellate manner. The capitulum (head) may also consist of only one kind of florets, e.g., only tubular florets in Ageratum or only ray or strap-shaped florets in Sonchus. Each cluster of flowers in this type of inflorescence represents … It is of two types; viz. a) arranged in basipetal succession. At the same time there is a considerable saving of material in the construction of the corolla and other floral parts. Example: Waxflower. Ex: Dolichos plant. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? Types of Inflorescence . Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. From the main axil, lateral axil arises, on which flowers you can find the flowers. The flowers are unisexual; the female flowers develop at the base of the cavity and the male flowers towards the apical pore. 1. Types of Inflorescence This type is also called definite or determinate infloresence. The first two are monochasial (one flower at each node) in the form of scorpioid cymes. racemose and cymose. 1) Raceme Here pedicellate flowers are present on peduncle. The typical examples are found in Poaceae (Gramineae) family such as-wheat, barley, sorghum, oats, etc. Ex: Croton plant. In addition the whole inflorescence remains surrounded by a series of bracts arranged in two or three whorls. The special type of inflorescence found in Ficus where the female flower are at bottom and male flower near ostiole and enclosed within a cup shaped fleshy thalamus (receptacle) with ostiole is called [BHU 2002; Manipal 2000] ... B. CYMOSE INFLORESCENCES: In this type of inflorescence the growth of main axis is stopped by the development of a flower at its apex. A spike of unisexual flower is found in . Flowers are present in an acropetal manner; Cymose: In the cymose type of inflorescence, the main axis does not grow continuously. Inflorescence, in a flowering plant, a cluster of flowers on a branch or a system of branches. From the axil of each leaf, inflorescence develops. In both cases, the basal portions of the successive daughter axes become straightened up, to form a false central axis or Sympodium. Uniparous Cyme: The main axis ends in a flower below which a daughter axis is produced which again ends in a flower. Examples include Salvia, Ocimum, Coleus etc. Spikeletes are arranged in a spike inflorescence which is composed of several to many spikelets which are combined in various manners on a main axis called the rachis. Also known as spadix of spadices. The inflorescence in which branching of the main axis or peduncle is racemose or cymose is called simple inflorescence. At the same time the peduncle produces two lateral younger flowers or two lateral branches each of which terminates in a flower. (i) With the main axis elongated, i.e., (a) raceme; (b) spike; (c) spikelets; (d) catkin and (e) spadix. Umbel: The main axis is … The inflorescence may also be Terminal when the vegetative axis is continued into the main axis of the inflorescence, or Lateral, when it arises away from the apex, as is Sweet Pea. Racemose Inflorescence Based on Flattened Main Axis: Capitulum: In this type of inflorescence the main axis becomes suppressed, flat and the flower becomes sessile i.e without talk so that they can make crowded patterns together on the flat surface of receptacle. In determinate (cymose) There are three flowers; the oldest one is in the centre. The various forms of racemose inflorescence may be described under three heads. d) fig. The lateral and succeeding branches again produce only one branch at a time like the primary one. Racemose Inflorescence 2. Dans une inflorescence définie, … E.g. In this type of inflorescence the growth of the main axis is ceased by the development of a flower at its apex, and the lateral axis which develops the terminal flower also culminates in a flower and its growth is also ceased. This type of inflorescence is found in genus Euphorbia of family Euphorbiaceae; also found in genus Pedilanthus of the family. All the flowers appear at the same level. Old flowers present at apex and young flowers at base. The stalk of the lower flower is longer than younger upper flowers. The capitulum inflorescence has been considered to be the most perfect. Examples – Radish (Raphanus sativa), Mustard (Brassica compestris), Casia, etc. mustard, radish, goldmohur etc. The arrangement of flowers on a branch system is known as inflorescence.The inflorescence axis bearing the flower is known as peduncle and the stalk of individual flower is called pedicel. previous. Usually the lemma also known as inferior palea bears a long awn as an extension of the mid-rib at the apex or back. The receptacle is surrounded at the base by overlapping bracts which form an Involucre. The examples are found in genus Ficus of Moraceae family, e.g., Ficus carica, F. glomerata, F. benghal- ensis, F. religiosa, etc. Sometimes, in monocha­sial or uniparous cyme successive axes may be at first curved or zig-zag (as in scorpioid cyme) but later on it becomes straight due to rapid growth, thus forming a central or pseudoaxis. Examples of how to use “cyme” in a sentence from the Cambridge Dictionary Labs In this inflorescence there is a cup-shaped involucre, often provided with nectar secreting glands. B1. Corymb: In this type of inflorescence peduncle is short with pedicellate flowers. The lateral and succeeding branches in their turn behave in the same manner, e.g., jasmine, teak, Ixora, Saponaria, etc. Various types of compound inflorescences met within angiosperms are: In some inflorescences, the daughter axes are extremely reduced and are crowded in many groups. ), oak (Quercus spp. Types of inflorescence in plants. There is an arrangement of flowers in them is centrifugal i.e., the young flowers are towards the periphery and the older ones towards the center. The different types of the cymose inflorescence are: Monochasial/Uniparous – the main axis ends in a flower and has one lateral branch. This inflorescence is found only in monocotyledonous plants. In this inflorescence a whorl of bracts forming an involucre is always present, and each individual flower develops from the axil of a bract. The florets are arranged in a centripetal manner on the receptacle, i.e., the outer flowers are older and open earlier than the inner ones. The inflorescence may be simple. Example: thalis. Cymose Inflorescence may be Uniparous, Biparous, or Multiparous. The process is repeated many times. One may also ask, what are the types of Racemose inflorescence? Compound 4. In such cases the main axis remains elongated and it bears laterally a number of stalked flowers. Uniparous cyme is of two types: An inflorescence may be; simple, compound or of special types according to the mode of branching. The lower or older flowers possess longer stalks than the upper or younger ones, e.g., radish (Raphanus sativus), mustard (Brassica campestris), etc. In this type of cymose inflorescence the main axis culminates in a flower, and at the same time it again produces a number of lateral flowers around. Cymose Inflorescence: Inflorescence: Type # 3. Inside the involucre, surrounding the stalk. Zinnia, Cosmos, Tridax, Vernonia, etc. Our mission is to provide an online platform to help students to share notes in Biology. When the main axis of raceme is branched and the lateral branches bear the flowers, the inflorescence is known as compound raceme or panicle, e.g., neem (Azadirachta indica), gul-mohar (Delonix regia), etc. Inflorescence is divided into two main types: Racemose: In racemose types of inflorescence, the main axis grows continuously and flowers are present laterally on the floral axis. Just above the glumes, there is series of florets, partly enclosed by them. The lemma is the lower, outer bract of the floret. Welcome to BiologyDiscussion! The oldest flowers are towards the base of the inflorescence and the youngest ones towards the apex. When the lateral branches develop on alternate sides, forming a zigzag, the cymose inflorescence is known as scorpioid or alternate-sided cyme, e.g., in Gossypium (cotton), Drosera (sundew), Heliotropium, Freesia, etc. Here the main axis ends in a flower and it produces only one lateral branch at a time ending in a flower. compound, mixed or special types. This type of inflorescence is a condensed form of dichasial (biparous) cyme with a cluster of sessile or sub-sessile flowers in the axil of a leaf, forming a false whorl of flowers at the node. It is further divided into 3 types based on growth pattern of main axis. A cymose inflorescence is one whose rachis (simple or branched) becomes terminated by a flower bud at an early stage and subsequent buds are developed gradually towards the lower side of the axis. Verticillaster: When flowers arise in the axil of bracts arranged opposite to each other. a) wheat. It is also called Sympodial Cyme, therefore. This type of inflorescence is characteristic of the composite. b) onion. Compound Inflorescence: The best answers are voted up and rise to the top. The third (Snow-in summer) and fourth (Stitchwort) are dichasial (two flowers at each node). The stalk of the lower flower is longer than younger upper flowers. They are categorized generally on the basis of the timing of their flowering and by their arrangement on an axis. Also known as corymb of corymbs. In this type of inflorescence the main axis does not end in a flower, but it grows continuously and develops flowers on its lateral sides in acropetal succession (i.e., the lower or outer flowers are older than the upper or inner ones). The reasons are as follows: The individual flowers are quite small and massed together in heads, and therefore, they add to greater conspicuousness to attract the insects and flies for pollination. d) cymose 2. Typical examples, are—Ocimum, Coleus, Mentha, Leucas, etc. Cette disposition, dont le motif s'apparente à une fractale, est souvent caractéristique dune famille, par exemple le spadice des Aracées, et lui a parfois donné son nom : l'ombelle est l'inflorescence typique des Ombellifères (aujourd'hui Apiacées), le capitule celle des Composées (aujourd'hui Astéracées). In this type of inflorescence the peduncle bears a terminal flower and stops growing. Central axis stops growing and ends in a flower, further growth is by means of axillary buds. In this type of inflorescence the main axis or receptacle becomes suppressed, and almost flat, and the flowers (also known as florets) are sessile (without stalk) so that they become crowded together on the flat surface of the receptacle. 1. Besides, there is also a special type of inflorescence which fits into none of these groups. E.g. The central axis of the inflorescence (peduncle) possesses terminal bud which is capable of growing continuously and produce lateral flowers is called racemose inflorescence. Some examples are acacia, albizzia. Terminal inflorescence is one where the inflorescence develops on the tips of the main stem and branches. Special Types of Inflorescence: 1. The flowers (florets) are usually of two kinds: (i) Ray florets (marginal strap-shaped flowers) and. It is easy to confuse the characteristics of the two types and consequently, it is vital you note their differences. The examples can be seen in poinsettia (Euphorbia), Pedilanthus, etc. This type of inflorescence is known as sympodial cyme as found in some members of Solanaceae (e.g., Solanum nigrum). 1.An inflorescence in which flowers arise from different point but reach at same point is known as. Share Your PDF File The flowers are borne in a … b) arranged in acropetal succession. An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. When the lateral axes develop successively on the same side, forming a sort of helix, the cymose inflorescence is known as helicoid or one-sided cyme, e.g., in Begonia, Juncus, Hemerocallis and some members of Solanaceae. This inflorescence (umbel) is characteristic of Apiaceae (Umbelliferae) family. The main axis of the inflorescence is called Peduncle. Here the main axis (peduncle) branches in a corymbose manner and each branch bears flowers arranged in corymbs. ), latjira (Achyranthes aspera), etc. Inflorescence The arrangement of flowers on floral axis or peduncle resulting in formation of groups is called inflorescence. Each floret has at its base a lemma and palea. Spike: The main axis elongated bearing sessile flowers, as in Verbena, Bottle-brash. Answer Now and help others. a) catkin. What is the significance of transpiration? corymb Inflorescence composed of a main axis and laterally borne flowers with pedicels of unequal length, all ending at the same height. The typical example is globe thistle (Echinops). In this plant the heads are small and one-flowered and are arranged together forming a big compound head. The stalk of the individual flower of the inflorescence is called the pedicel. At the base of the cup, the female flowers develop while towards mouth the male flower develops. Is this an example of necrosis or apoptosis? In botany, a spadix (/ ˈ s p eɪ d ɪ k s / SPAY-diks; plural spadices / ˈ s p eɪ d ɪ s iː z / SPAY-dih-seez, / s p eɪ ˈ d aɪ s iː z / spay-DY-seez) is a type of spike inflorescence having small flowers borne on a fleshy stem. It is difficult to make out the real mode Of branching in them. The examples are common in Palmaceae (Palmae) family. Some examples of Cymose inflorescences are shown here. Here the peduncle (main axis) is short and bears many branches which arise in an umbellate cluster. The first of main floral axis gives rise to two lateral branches and these branches and the succeeding branches bear only one branch each on alternate sides. The cymose inflorescence may be of four main types: (iii) Multiparous or polychasial cyme and. The main axis of a racemose inflorescence is sometimes may be compressed and flattened into a disc, bearing a cluster of flowers on its upper surface. Axillary inflorescence; Intercalary inflorescence. Before sharing your knowledge on this site, please read the following pages: 1. Cyathium: A cup-shaped involucre having nectar-secreting glands, a centrally placed single large female flower which is reduced to pistil, and many male flowers present in the form of stamens, e.g., Euphorbia. Besides, it is also found in Acacia and sensitive plant (Mimosa pudica) of Mimosaceae family. This is a simple polychasium. Here the flowers are borne on the inner wall of the cavity. Here the flowers develop in basipetal succession, i.e., the terminal flower is the oldest and the lateral ones younger. The whole inflorescence looks like an umbel, but is readily distinguished from the latter by the opening of the middle flower first, e.g., Ak (Calotropis procera), Hamelia patens, etc. d) of the same sexes. types of inflorescences Inflorescence: the arrangement of flowers on the stem or twig of a plant. An inflorescence is actually a closely branching in most plants the flowers are borne in groups but in some, they occur singly and are called Solitary. Also known as umbel of umbels. Simple racemose inflorescence is of following types. Corymb: In this type of inflorescence peduncle is short with pedicellate flowers. In such cases the peduncle is reduced or condensed to a circular disc. The axillary inflorescence is one that originates from the leaf axils. The capitulum may be homogamous, if all flowers are of the same kind, as in Sonchus, in which the flowers are ligulate (strap-shaped) and bisexual, or heterogamous, in which the flowers are of two types, as in sunflower, the Disc-Florets, tubular and bisexual, occupying the center of the receptacle and the ray florets, ligulate and pistillate or neuter, present at the periphery of the receptacle. next. Some of the common types of inflorescences are as follows: Spike: The flowers, which are with a very short or with no pedicel, are attached along the elongate and unbranched peduncle of the inflorescence (examples: plantain, spearmint, tamarisk). Inflorescence can be broadly classified based on the following: Number and position of flowers Sequence of flower development The nature of inflorescence branching However, the common classifications of inflorescence are Racemose and cymose. In this type of inflorescence the receptacle forms a hollow cavity with an apical opening guarded by scales. Simple cyme (solitary): Determinate inflorescence consists of a single flower. Cymose Inflorescence: Cymose Inflorescence may be Uniparous, Biparous, or Multiparous. A capitulum or head is characteristic of Asteraceae (Compositae) family, e.g., sunflower (Helianthus annuus), marigold (Tagetes indica), safflower (Carthamus tinctorius). The former whorl of bracts is called involucre and the latter involucel. Although there has been a recent attempt to model the development of some basic inflorescence types, and to determine their position in an adaptive landscape (Prusinkiewicz et al., 2007), there is as yet no comprehensive theory that addresses the complexities of inflorescence structure and function, and thus no comprehensive terminology that can satisfy all needs. 4. Each male flower is reduced to a solitary stalked stamen. Verticillaster 6. In this, the axes are extremely reduced and the perianth leaves are completely suppressed. The flowers may be pedicellate (stalked) or sessile (without stalk). When branching of the main axis or peduncle is either racemose or cymose, the inflorescence is known as Simple. Simple inflorescence. Share Your Word File c) mulberry. (b) Helicoid Cyme: Successive daughter axes are developed on the same side, either right or left, forming a spiral, e.g., in Begonia and some Solanaceae. All the flowers appear at the same level. Racemose Inflorescences is type of flower arrangement in plant. It may be terminal or axillary. Typical example-cauliflower. It bears sessile or sub-sessile flowers on it. Flowers and glumes are arranged on the spikelet in two opposite rows. This type of inflorescence is found in Acacia, Mimosa and Albizzia. There are three main types of inflorescence – racemose, cymose, and special type. Some are in compound spikes (i.e., in wheat—Triticum aestivum), others are in racemes (e.g., in Festuca), while some are in panicles (e.g., in Avena). (ii) With the main axis shortened, i.e., (i) corymb and (ii) umbel. Simple Inflorescence A simple inflorescence maybe racemose or cymose according to the mode of branching. After reading this article you will learn about: 1. In raceme the flowers are. In a cymose inflorescence, the flowers usually form Clusters. The intercalary inflorescence is one that is borne at the internodes of the stem. In this case many small heads form a large head. Disclaimer Copyright, Share Your Knowledge (ii) Disc florets (central tubular flowers). 2. Which part of the male reproductive system store the sperm? If the main axis of the inflorescence is branched and the branches bear flowers in the same manner as are present on the main axis, the inflorescence is called a compound Inflorescence. All three types of flowers are … In this type of racemose inflorescence the main axis remains elongated and the lower flowers are older, i.e., opening earlier than the upper ones, as found in raceme, but here the flowers are sessile, i.e., without pedicel or stalk, e.g., amaranth (Amaranthus spp. 3. It is evident that each stamen is a single male flower from the facts that it is articulated to a stalk and that it possesses a scaly bract at the base. The flowers make a globose head, which is also called glomerule. The main axis of the inflorescence together with the latest axes, if present, is termed as the peduncle. Sometimes, the umbel is un-branched and known as simple umbel, e.g., Brahmi (Centella asiatica). and overview is provided to identify the type of Racemose Inflorescence. In the former case it becomes a compound raceme and in the latter case it becomes a compound cymose inflorescence. Privacy Policy3. It may be terminal or axillary in position. The usual structure of spikelet is as— There is a pair of sterile glumes at the base of spikelet, the lower, outer glume called the first, and the upper, inner one called the second. Here the main axis (peduncle) remains branched in a racemose manner and each branch bears sessile and unisexual flowers. The solitary flower may be Terminal, when it is borne at the tip’ of the main stern or of its branch as in Poppy, or Axillary, when it is situated in the axil of a leaf, as in Garden Nasturtium.
