A usually flat-topped or convex determinate inflorescence in which the central main stem and each side branch end in a flower. Notably, there are two types of helicoid – drepanium and bostryx. In determinate inflorescence, young budding flowers can be found at the bottom, while in indeterminate inflorescence young buds are at the top. Helicoid – In this type of uniparous cyme, the branches keep growing on the same side only and ultimately form a helix. The flowers stay open for a shorter time, and occurrence of this type of flowering arrangement is shorter. The different types of the cymose inflorescence are as follows – monochasial cyme, dichasial cyme, multiparous cyme and cymose head. biparous cyme Inflorescence whose main axis ends in a flower under which two lateral twigs develop; the process is repeated under each terminal flower. Specialized terminology can be applied depending on the type of cyme. The inflorescence is a modified form of a flower but looks like a bunch of flowers.

Racemose inflorescence falls under indeterminate category while cymose inflorescence is of determinate inflorescence type. These flowers are termed to as terminal solitary cyme and axillary solitary cyme correspondingly. A cyme developing along two axes may be a dichasium, compound dichasium, or compound cyme. In this type, the peduncle or the main stem is in the shape of a circular disk. In the wild form the outer flowers only of the cyme are sterile, and these are about three-quarters of an inch across; the centre is filled with small perfect flowers. Jasmine, Teak Saponaria; Polychasial cyme: It is known as multiparous cyme. Multiparous cyme/Polychasial: Here, the peduncle ends in a flower and from the base of it many lateral branches arise, which also terminate in flowers. The globose head is also known as glomerule. Each flower is borne on a short stalk, called a pedicel. The globose head is also known as glomerule. Examples of racemes occur on mustard (genus Brassica) and radish (genus Raphanus) plants. A compound raceme, also called a panicle, has a branching main axis. Monochasial cyme can be classified into three types. What is the Primary Difference Between Cymose and Racemose Inflorescence? Dichasial cyme: It is known as biparous cyme. A cyme developing along only one axis may be a elicoid cyme (bostryx), scorpioid cyme (cincinnus), rhipidium or drepanium.
