patent flowers, and approaches the P. astragalina ; but its flowers are always considerably smaller, of a far 

 deeper colour, and the leaflets are much narrower. It is a very elegant species.

Hab. Plains of the Saskatchawan. Drummond. — Stems 1 to 2 feet long, scarcely branched. Leaves 

 4 to 6 inches long. Leaflets an inch long. Racemes, including the peduncle, 6 to 8 or 10 inches in length, 

 with numerous closely-placed, drooping, rich i^ur^Xe flowers, nearly an inch long; carina and al(B pale at their 

 base. Legumes pendent, an inch long, between membranaceous and cartilaginous, narrow, cylindrical, acute 

 at the point, with the style often deciduous, at the base attenuated into a stipes as long as the calyx, one-celled,

 accord with those sent me from the opposite side of Behring's Straits, by Dr. Fischer. One of the indiyi-
