Fig. Compound Umbel. A Compound Umbel has a second umbel, or um-bellet, upon each pedicel. IsToTE.—Most of the clusters pictured in this exercise arerepresented as without bracts, that differences in their modesof branching may be more easily compared. The picturesrepresent certain styles of flowering, and each of these stylesvaries very much in nature. You will find umbels very unlikeeach other, and very unlike Fig. 170, but still more nearly likethat figure than any of the others. And so of panicles, co-rymbs, &c. Great differences among the clusters of one varietymay be occasioned by the presence or absence of bracts, bytheir groupings, forms, and colors, by the length, stiffness, andeven varying positions of peduncles and pedicels, as well as bydifferences in the form of receptacles. And besides, the vari-ous sorts run together in many different ways. You willsometimes find a flower-cluster resembling two different varie-ties so much that you will have to combine the names of the
