Thenamed garden forms of Chinaaster are several hundred. Asearly as 1895, American seeds-men offered varieties. Someof the forms are shown 424-427. For botanicalaccount of the China aster, 425. China aster, the Branch-ing type. It is impossible to construct a satisfactory classifica-tion of the China asters. It is no longer practicable toclassify the varieties by color. Neither is it feasible toclassify them uponhabit or stature ofplant, for several ofthe best marked typesrun into both tall and .-7^dwarf forms. Vil- (i^morin, however, dividesthe varieties intotwo main groups, thepyramidal growers,and the non-pyramidalgrowers. The mostelaborate classificationis that proposed byBarron, from a studyof extensive tests madeat Chiswick, has 17 sections,but they are notcoordinate, and theyare really little morethan an enumerationof the various typesor classes. After con-siderable study of the varieties in the field and her-barium, the following scheme seems to be serviceable: A.
