A Compound raceme is a cluster of racemes racemosely arranged, as in Smilacina racemosa. A compound corymb is a corymb some branches of which branch again in the same way, as in Mountain Ash. A compound spike is a spicately disposed cluster of spikes. 217. A Panicle, such as that of Oats and many Grasses, is a compound flower-cluster of a more or less open sort which branches with apparent irregularity, neither into corymbs nor racemes. Tig. 209 repre- sents the simplest panicle. It is, as it were, a raceme of which some of the pedicels have branched so as to bear a few flowers on pedicels of their own, while others remain simple. A compound panicle is one that branches in this way again and again. 218. Determinate Inflorescence is that in which the flowers are from terminal buds. The simplest case is that of a solitary terminal flower, as 209
