A Spfldix is a spike with small flowers crowded on a thick and fleshy body or axis. Sweet-Flag and Indian-Turnip are common examples. In Indian-Tur- nip (Fig. 147) the spadix bears flowers only near the bottom, but is naked and club-shaped above. And it is surrounded by a peculiar leaf or bract in the form of a hood. 185. Such a bract or leaf enwrapping a spike or cluster of blossoms is named a Sjjcithe. 186. A set of bracts around a flower-cluster, such as those around the base of the umbel in Fig. 144, is called an Involucre. 187. Any of these clusters may be compound. That is, there may be racemes clustered in racemes, making a compound raceme, or corymbs in corymbs, or umbels in umbels, making a compound umbel, as in Caraway (Fig. 148), Parsnip, Parsley, and all that fiimily. The little umbels of a compound umbel are called Umbel- lets; and their involucre, if they have any, is called an Involucel. 188. A Panicle is an irreg- ularly branching compound fl jwer-cluster, such as would bo formed by a raceme with its lower pedicels branched. Fig. 149 shows a simple ])anic]e, the branches, or would be the pedicels, only once branched. A bunch of Grapes and the flower-cluster of Horsechestnut are more compound panicles. A crowded compound panicle of this sort has been called a Thyrse. 180. A Cyme is the general name of flower-clusters of the kind in which a flower always terminates the stem or main peduncle, and each of. 147 SpatUx and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gray, Asa, 1810-1888.
