1894. 
Prostrate and climbing on bushes, from a slender, ligneous 
root; stems 4 dm.—I m. or more long, retrorsely and finely hir- 
sute; stipules minute, subulate; petioles 1-5 cm. long; leaflets 
2-5 cm. long, ovate-oblong or rarely lanceolate-oblong, obtuse, 
often retuse, mucronulate, rarely acutish, glabrous or somewhat 
pilose above, lighter, minutely pubescent or pilose beneath; ra- 
cemes 2 or 3 cm.—2.4 dm. long, often slender and filiform ; flowers 8— 
10 mm. long, lilac or pink-purple; bracts and bracteoles minute; 
calyx 6-8 mm. long, attenuate in bud, glabrate or somewhat pilose, 
* This species is based on the Dillenius plate cited below and is most variable 
and difficult to define, The type specimen is evidently the larger leaved, long- 
racemed form that occurs principally from North Carolina to Florida on the coast, 
and has been confounded with G. mo//is Michaux. The more northern plant has usually 
shorter racemes, the upper part of which often falls off before maturity of the cuit, 
which gives the appearance of very short, sometimes sessile racemes. a has in its 
more southern limits been confounded with G. tenuiflora (Willd.) Wight and Arn. 
An original type specimen of Wight Nos. 874 and 875 from Coleman; East er 
Peninsula preserved in Herb. Columbia College differs materially from the Nort 
American plant. G. ¢enuiflora occurs in South America and is i in Index 
Kewensis to G. dubia DC. Prod. 2: 238. Galactia Macreet, the type speci- 
men of which is preserved in Herb. Columbia College, is merely a very slender fili- 
form-racemed variation.
