The flowers of Sorbus aria , whitebeam, form a corymb in which all the lateral branches are of different lengths, with the lowermost of greater length so that all the flowers are brought to the same level. The main axis in racemose inflorescence continues to grow and produce flowers laterally. 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. A corymb is a raceme in which the pedicels of the lower flowers are longer than those of the upper flowers so that the inflorescence has a flat-topped appearance overall, as in hawthorn ( Crataegus ). corymb: a racemose inflorescence in which the pedicels of the lower flowers are longer than those of the flowers above, bringing all flowers to about the same level.

Candytuft; Umbel: An inflorescence in which the flower stalks are of more or less equal in length, arise from the same point. The inflorescence of Astrantia major, the masterwort, is a compound umbel (C) in which the lateral branches are themselves subdivided. Examples of secondary inflorescences are "a panicle of spikelets," "a corymb . 6) Corymb . INFLORESCENCES. Upper flowers have much shorter pedicel than the lower ones, so that all the flowers are brought more or less to the same level. An indeterminate inflorescence may be a raceme, panicle, spike, catkin, corymb, umbel, spadix, or head. Compare our chart's corymb with the umbel, which is also flat-topped. a.

Corymb Some examples of racemose inflorescence include spike, raceme, corymb, umbel, and head. Example: Waxflower. rachis) developing from an underground stem is known as scape. These florets are arranged in a centripetal manner on the . Inflorescence with reduced growth of central axis. Here main axis is comparatively short. ADVERTISEMENTS: In this article we will discuss about the Inflorescence in plants:- 1. 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. (a) Corymb: 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). Yarrow, Boneset, and Hawthorn are all examples. Example: onion. Examples include hydrangea and hawthorn. There are two types, namely corymb and umbel.

Moreover, some inflorescences are associated with particular plant families, for example: umbels in the carrot family (sometimes thus called the "Umbelliferae"); spikelets in the grass . The peduncle is the part of the stem which extends to bear a flower. Inflorescence types are essentially secondary arrangements. Racemose inflorescence can be divided into two types, simple and compound, depending on the development of the main axis and pedicels of the flowers. The main axis of inflorescence is called peduncle. They are generally arranged in a fixed pattern we call inflorescence. This come from the French word cime, meaning 'top/summit'.

Inflorescence may be terminal or axillary. An example is Acalypha. D) Corymb: The main axis is short. 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. Cyme. In corymb infloresence, which is a relatively shorter and broder raceme, the pedicel of lower flowers are longer than the upper ones and all the flowers reach the same level (Fig 10.1 e). Example: Caesalpinia. The pattern of flower arrangement on the floral axis is known as inflorescence. Under the appropriate environmental conditions, the wild-type Arabidopsis plant develops a racemose inflorescence, generally with three axillary inflorescence branches, and then produces an indeterminate number of flowers. This is pretty much a panicle, only with the flowers all coming to a flat top instead of a loose blobular deal. Umbel : The flowers are with pedicles, which are all attached at about the same point at the end of the peduncle this is specifically called a simple umbel .
