discovered in Canada in the year 1819- 
which I returned to Montreal, and, embarking in a vessel which 
was bound for Greenock, got safely home ; the plants which I 
carried with myself .being the whole that I saved out of the 
produce of nearly three years spent in botanical researches. 
In spite of the ill fortune which has hitherto attended my 
endeavours, I have still so great a desire to bring American 
plants and seeds to this country, that I purpose, in the ensuing 
spring, if my pecuniary circumstances will permit me, to make 
another excursion to that country, for the purpose of explo- 
rinff the forests which lie towards the west.

Although this species is described by Pursh under the name 
of S. corniculata^ yet he, with great propriety, intimates, that 
the American plant is distinct from the original Siberian one of 
that name, principally on account of the deflexed horns of the 
corolla. The present individual is annual or biennial, smooth, 
6-8 inches high, simple, somewhat four-angled. Lower leavm 
spathulate, the rest ovato-lanceolate, all opposite, three-nerved. 
Flowers axillary and terminal ; the axillary ones upon bibrac- 
teated racemes, the terminal ones nearly umbellate, with four 
small leaves at the base resembling an involucre. Calyx 
deeply four-partite, the segments lanceolate, rising erect be- 
tween the horns of the corolla. Corolla erect, almost campa- 
nulate, veined, greenish-yellow, purplish below, divided into 
four, ovate, acute segments, and at the base furnished with four 
deflexed horns, more than half as long as the corolla. Stamens 
four, inserted about the middle of the corolla, alternate with the
