It has two clusters of sessile flowers developing from the two opposite axils of leaves. Name the types of nitrogenous bases present in the RNA. The various forms of racemose inflorescence may be described under three heads. A compound cyme is one in which there is an initial branch and then one or more branches. Figure 1 shows four basic inflorescence architectures: a single flower (A), raceme (B), cyme (C), and panicle (D). Cymose or other complex inflorescences that are superficially similar are also generally called thus. The typical example is globe thistle (Echinops).
