with unequally pinnate leaves of 9 - 13 leaflets, and minute stipules, with 

 lilac-colored flowers in large racemes.

 ovary glabrous. 



Yirginia, South and West. May. 

 Woody Wistael^. Glycine. Carolina Kidney Bean. 



2. W. Chixen'sis, DC. Wings of corolla 1-auricledat base ; ovary hairy.

Chinese Wistaeia. Glycine. 



Obs. These beautiful vines, the one a native of the rich alluvial soils 

 of the southern portion of the Union, and the other from China, are 

 eminently worthy of cultivation. They both grow readily, are quite 

 hardy, and may be propagated with the greatest ease. The Chinese 

 species is most generally cultivated, its flower racemes being much 

 larger than in the native one ; but the other is much darker colored,

Southern States : cultivated. Native of Asia and Africa. 



Ohs. This plant, so important in yielding a blue coloring matter — 

 was formerly cultivated to a considerable extent, in Georgia, and some
