A peduncle bearing a terminal flower and two bracteoles, which subtend lateral stalked flowers (simple dichasium); two stalked flowers in its axils.
A compound dichasium repeats this branching pattern on the lateral axes.
A forked cyme, with the oldest flower in the first fork (at the stem-head) and the next oldest flowers terminating the opposite side-branches; successive opposite pairs of branches arise below each terminal flower, and the process is repeated.
A cyme with side branches approximately opposite and equal, always longer than the main stem.
