Example:- oscimum, salvia etc. coconut. The type of inflorescence is characteristic of Lamiaceae (Labiatae) family. Racemose Inflorescence: In this type of inflorescence the axis continues its growth until the last e flower is formed at its apex. Raceme: Flowers with pedicel and are in an acropetal arrangement. 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. The two types of uniparous are Helicoid cyme and Scorpioid cyme. Capitulum: Inflorescence is the collection of numerous florets organized on a central platform called receptacle with two distinct floret types- the central disk (tubular) florets and peripheral ray (ligulate) florets. With Long Main Axis. rachis) developing from an underground stem is known as scape. The first two are monochasial (one flower at each node) in the form of scorpioid cymes. Racemose : This is further divided into (a) Raceme, (b) Catkin, (c) Spike, (d) Spadix, (e) Corymb, (f) Umbel, (g) Head or Capitulum. III. Example is mustard. Examples are calotropis, hamelia patens etc. Examples of secondary inflorescences are "a panicle of spikelets," "a corymb of heads," or "a raceme of spikes."
