A, panicle ; B, raceme ; C, spike ; D, umbel; E, head. panicle, like that of the oat (Fig. 134).1 Other forms of compound racemes have received other names. An umbel may become compound by the branching of its flower-stalks (Fig. 135), each of which then bears a little umbel, an umbellet. 202. Inflorescence Diagrams. — The plan of inflorescence may readily be indicated by diagrams like those of Fig. 136. The student should construct such diagrams for some rather corn- plicated flower-clusters, like those of the grape, horse-chestnut or buckeye, hardhack, vervain, or many grasses. 1 Panicles may also he formed by compound cymes (see Sect. 204)..
