Stem 4-10 feet long, pubescent, climbing over shrubs and bushes. Leaflets 2-3 inches 

 long, and often nearly as broad as long ; under surface clothed witli short uncinate hairs, by 

 which the leaves adhere to paper, clothing, etc. Stipules small, lanceolate. Racemes nu- 

 merous, 4-12 inches long, slender, loosely flowered : pedicels filiform, 2-4 lines long, with 

 3 minute hairy bracts at the base. Calyx campanulate, much shorter than the corolla, some- 

 what bilabiate. Corolla purple. Legume 2 - 2^ inches long and 4-5 lines wide, strongly
