How plants grow [microform] : a simple introduction to structural botany : with a popular flora, or an arrangement and description of common plants, both wild and cultivated : illustrated by 500 wood engravings. Botany; Botanique. 02 HOW PLANTS ARE PROPAOATED. II m It 184. A Spadil 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 Spathe, 186. A set of bracts around a flower-cluster, such ba 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 family. 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 flower-cluster, such as would be formed by a raceme with its lower pedicels branched. Fig. 149 shows a simple panicle, the branches, or what would be the pedicel?), ^^3 only once branched. A compound ii«b,i. bunch of Grapes and the flow^er-cluster of Horsechestnut are more compound panicles. A crowded compound panicle of this sort has been called a Thyrse, 189. 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.
