In meadows, pastures and thickets, very common. 



Perennial. Julij, August. 



Root creeping extensively, beset with fleshy tubercles, which ren- 

 der it very tenacious of life. Herb mostly smooth, of a slightly 

 glaucous green, turning blackish in drying; not unfrequently 

 a little rough or hairy. Stems weak, climbing, branclied, leafy, 

 acutely angular, not winged, rising to the height of 2 or 3 feet. 

 Tendrils for the most part simple, sometimes divided ; each ac- 

 companied by a pair of lanceolate, acute, variously ribbed leaf- 

 lets. Stipulas unequally arrow-shaped, taper-pointed. Flowers 

 bright yellow, larger than the foregoing, 8 or 9 together, on 

 long, upright, angular stalks. Cal. hairy, with slender, not very 

 deep, teeth. Legumes nearly upright, black, smooth, compress- 

 ed, sparingly produced. Seeds 8 or 10, smooth. 



Cattle are fond of this plant, which makes a great part of common 

 meadow hay. It thrives on a wet clay soil, and has been re- 

 commended by Dr. Anderson for cultivation.
