A flower that is not part of an inflorescence 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.

Any flower in an inflorescence may be referred to as a floret, especially when the individual flowers are particularly small and borne in a tight cluster, such as in a pseudanthium.

What is Cymose and racemose?
Racemose and cymose are two types of inflorescence, i.e. arrangement of flowers around the main axis. In racemose, the main axis continues to grow indefinitely and the flowers are borne laterally. In cymose inflorescence, flowers are borne terminally on the floral axis and shows determinate growth of the main axis.
What is a Zygomorphic flower?
Definition of zygomorphic of a flower. : having floral parts unequal in size or form so that the flower is capable of division into essentially symmetrical halves by only one longitudinal plane passing through the axis.
II. Racemose Inflorescence
Racemose inflorescence is an indeterminate inflorescence which shows indefinite growth and bears a number of flowers due to the presence of active growing points.
III. Cymose Inflorescence
Cymose inflorescence is the name of determinate or definite inflorescence in which the tip of the main axis terminates in a flower and further growth continues by one or more lateral branches which also behave like the main axis.
IV. Special Types of Inflorescence
Special types of inflorescence are basically cymose but ultimately it is modified to form a special appearance.
V. Mixed Inflorescence
Mixed inflorescence have both the characters of racemose and cymose type of inflorescence. Some examples of mixed inflorescence are as follows:
Which cyme is alternately borne on both sides?
lowers are alternately borne on both the sides, e.g., Freesia, Tecoma, Heliotropium, Ranunculus bulbosus. A modification of scorpioid cyme is rhipidium. Here all the flowers are borne in one plane, e.g., Solanum nigrum.
How many flowers are in a cluster of cymes?
Two clusters, each having 3-9 flowers, develop on a node in the axils of opposite leaves. Each cluster consists of a dichasial cyme with monochasial branches. The axis of the cyme is shortened so that all the flowers arise from a single point.
What are the two types of flowers separated by downwardly directed sterile hair or neuter flower?
The two types of flowers are separated by downwardly directed sterile hair or neuter flower, e.g., Colocasia, Arum. In a spadix the appendix of the peduncle and the spathe are coloured to attract insects for pollination. The spathe is tubular in the basal region to protect the flowers. ADVERTISEMENTS: 9.
What is a compound umbel?
Compound Umbel (Umbel of Umbels ). Several small or daughter umbels called umbellules arise from a common point in an umbellate fashion. A whorl of bracts, called involucre, is present at the base of the parent umbel. Similar whorls of bracts found at the bases of umbellule’s are called involucels.
What is the pore of hypanthodium?
Hypanthodium has a flask-shaped fleshy receptacle which possesses a narrow canal and a terminal pore at one end. The pore is surrounded by a few scales while the canal is lined by downwardly pointed hairs. Internally the receptacle bears male flowers towards the pore and female flowers towards the base.
What is the spherical ovary called?
Each carpel or pistil (also referred as a gynoecium) consists of a forked stigma, a short style and a spherical ovary. Each ovary (carpel) becomes a drupelet and the ripened cluster of drupelets (syncarp) is called a multiple fruit.

Go To Leaf Terminology Part 1. Go To Leaf Terminology Part 2. An inflorescence may be defined as a cluster of flowers, all flowers arising from the main stem axis or peduncle: 1. Cyme. Note: The term scorpioid cyme is more correctly referred to as helicoid cyme. 2. Umbel.
What is the spadix of arum?
The spadix emerges from a vase-shaped or funnel-like modified leaf or spathe which is often brightly colored. The spadix of some arums emit s a putrid odor that attracts carrion flies for pollination. The spadix of some aroids produces a remarkable amount of heat during cold weather.
What is a spathe?
Spathe: A leaf-like bract or sheath that envelops an inflorescence. In the arum family (Araceae), the vase-shaped or funnel-like spathe is often brightly colored. The most remarkable spathe surrounds the inflorescence (spadix) of the corpse flower (Amorphophallus titanum), so named because of the stench of the blossom.
