. Plant studies; an elementary botany. Botany. XEKOl'IIYTE SfX'lETIES 191. Fk;. lOii. The Epring beauty {Ciayto/'da}, showing subterranean tuber-like stem sending leaf and flower-bearing stern above the surface.—After Atkinson, turn of the moist season these underground parts develop new exposed surfaces. In such cases it nitty Ijc said tliat at the coming of the droutli the plant seeks a sub- terranean retreat. A little less decrease of C-xjiosed surface is shown hy the deciduous hiibit. It is known that certain trees and slirubs, whose Jjodies remain exposed to the drouth, shed their letives and thus very greatly reduce the amount of exposure ; with the return of mois- ture, new leaves are put forth. It will he re- marked, in this connec- tion, that the same habits serve just as well to bridge over a period of cold as a period of drouth, and perhaps they are more familiar in connection with the cold period than in con- nection with the drouth period. 136. Temporary reduc- tion of surface.—While the habits above have to do with regular drouth.
