Had. Pastures of tbe Saskatchawau, Drummond; and on the Red-Deer and Eagle Hills, bordering on 

 that river. Douglas. — This is a very remarkable species of Phacay differing from all its congeners in the great 

 length of the flowers, in tbe singularly thick and wrinkled fiitit, and above all, in the structure of its leaves. 

 The leaflets do not appear to be jointed upon the rachis, but to form a continued substance with them, and 

 to be rather deeply-pinnatifid in a pectinated manner, than really compound and pinnated. In proof of this, 

 the upper leaflet, which is, as it were, a prolongation of the rachis, is sometimes forked, and the rachis itself 

 I have observed to he so in two or three instances. The leaflets are therefore persistent, and remain upon 

 the withered rachis, like the segments of a simple leaf. Notwithstanding tbis peculiarity of structure in the 

 foliage, there is nothing, I think, iu the fructification, that would justify a separation of the plant from Phaca.

Hab. Dry, sandy, and barren grounds, at the Great Falls of the Columbia, rare. 1823. Fu June — 

 August. — This stands marked, in Mr. Douglas* collection, as a new genus ; and there is indeed something 

 very remarkable in the appearance of its legumes, compressed as they are and thickened at the sutures, 

 both above and below, and home upon a stalk as long as themselves. But it possesses all the essential 

 characters of Phaca, where I therefore place it.
