 lower one much longer. Coiolla large, about 3 times as long as the calyx, violet- 

 purple with tinges of green,— becoming greenish on shrivelling, and sometimes 

 deep blue. Legume long, mostly of 5 or joints, reticulately veined, uncinate]? 

 hispid and tenacious ; joints oblong-triangular, sometimes rather rhomboidal, or 

 obtusely angled on the upper margin. 

 Ilab. Moist grounds ; borders of thickets : frequent. Fl. July— Aug. Fr. Sept. 



Obs. Dr. Boott informs mo that this is the canescens, of Linn, and Clayton — 

 and the viridiflorum, of Pur&h. It is also, probably, the scubcnimum } of Elliott • 

 but I have some doubts whether the canesccns ) of Pers. Ait. Pursh, &c. be not 

 founded on Willdenow's plant of that name,— which is believed to be the rotund- 

 t/olium t Mx.
