The panicle is a compound inflorescence, formed by an irregular branching of the pedicels of the raceme. Ex. oats, Poa, and many other grasses. 305. The thyrse is the same as the panicle, having the lower branches rather shorter than those in the midst, and all of them very compact, as in the lilac (Syringa), horse-chestnut. a. The umbel becomes compound when each pedicel becomes itself an umbel, as in most of the UmbellifersB. In these cases the secondary umbels are called umbellets, and sometimes partial umhels. See ^ 254. By a similar decomposition, a raceme becomes a compound raceme, a corymb a compound corymb, FIG. 38. — Modes of inflorescence ; 1, raceme; 2, ament; 3, spadii; 4, head ; 5, panicle ; 6, verticiJlasler; 7, thyrse. , 306. Of the centrifugal inflorescence, the following varieties are described; namely, cyme, fascicle, and verticillaster. 307. Cyme. This inflorescence has the general aspect of the corymb, but is remarkably distinguished from it by its centrifu- gal evolution, and by its branches being repeatedly 2-forked and 3-forked, as exemplified in Hycbangea, Viburnum, chick- weed. a.
