length, and usually bears a single pair of small pinne ; when there are two pairs, these 
are somewhat approximate. The leaflets are only about one line in length, thickish, 
obscurely veiny, and perfectly smooth. The joints of the flat pod are one fourth of an 
inch in diameter. — The locality is somewhat north of lat. 37°; consequently this is the 
most northern species of the genus known. It is apparently quite distinct from any of 
those described in Mr. Bentham’s Synopsis (in Hook. Jour. Bot. vol. 4).— As this sheet 
is going to press, I have the opportunity of examining flowers of this species, sent me by 
Dr. Engelmann from a specimen gathered on the Upper Canadian in April, 1848, by 
Mr. Gordon. They have a truncate purplish calyx, five spatulate-oblong petals which 
are separate to the base, and ten distinct stamens.

but the original S. discolor, Pursh, I believe to be only S. ariefolia; as certainly is a
