longer than the leaves; 
flowers scattered on 
short pedicels. 
A vine climbing over small shrubs. Leaflets ovate and oval, mucro- 
nate, nearly glabrous on the upper surface, hairy underneath. Racemes 
6 12 inches long. Floivers scattered, 2 — 3 at each bud, on short pe- 
duncles. Calyx a little hairy. Bracteas small. Corolla pale purple. 
Legume villous. 
This species has great resemblance to the G. Glabella. It differs how- 
ever in its leaves which are smaller, more ovate, rather acute and muefo- 
nate, and in its racemes, which are much longer, with smallerflowers. I 
feel by no means certain that this is the plant of Mr. Nuttall. 
Grows in dry shady soils. 
Flowers through the summer.

glaucous. Style much longer than the stamens. Legume falcate. Seeds 
oval.
