 P. Caracalla, SNAIL-FLOWER. Stem twining extensively, rather woody 

 below, from a tuberous root ; leaflets rhombic-ovate, taper-pointed ; raceme's 

 longer than the leaf; flowers showy, 2' long, white and purple, the standard as

G. glabella. Sandy soil from New Jersey S. : prostrate, nearly smooth, 

 with rather rigid ovate-oblong leaflets, their upper surface shining, a few rather 

 large rose-purple flowers on a peduncle not exceeding the leaves, and a 4 - 6- 

 seeded at length smoothish pod. 



G. mollis. Sandy barrens, from Maryland S. : spreading, seldom twining, 

 soft-downy and hoary, even to the 8- 10-seeded pod ; racemes long-peduncled, 

 many-flowered ; leaflets oval. 



34. AMPHICARPJEA, HOG-PEA-NUT. (Name from Greek words 

 meaning double-fruited, alluding to the two kinds of pod. ) 11 



A. monoica. A slender much-branched twiner, with brownish-hairy 

 stems, leaves of 3 rhombic-ovate thin leaflets, and numerous small purplish 

 flowers in clustered drooping racemes, besides the more fertile subterranean

 fl. late summer and autumn. 



35. CENTROSEMA, SPURRED BUTTERFLY-PEA. (Name from 

 Greek words meaning spurred standard. ) 11 



C. Virginianum. Sandy woods, chiefly S. : trailing and low twining,
