I have no hesitation in referring to it the Tuermopsis rhom- 
bifolia of Dr. Ricuarpson. Thus it appears to have a very 
extended range, being found in the North-eastern parts of 
Asia, and in North America on both sides of the Rocky 
Mountains, but no where, as it appears, on the East side of 
that vast continent. It was introduced to this country 
through the Horticultural Society, having been sent by Mr. 
Doveuas from dry channels of mountain torrents, in the 
vallies of the Cordillera near the Columbia river. It is cul- 
tivated in the greenhouse of the Glasgow Botanic Garden, 
where it flowers in May: but Dr. Linptey speaks of it 
as a good herbaceous plant, readily increased by the divi- 
sion of its creeping roots: and it will probably prove quite 
a hardy plant. 
Drscr. Stem herbaceous, erect, simple, or branched only 
upwards, somewhat angular, quite glabrous below. Leaves 
trifoliate, petiolate : leaflets obovate, approaching to rhom- 
boid, distinctly veined, glabrous above, slightly downy be- 
neath. Stipules very large, foliaceous, nearly ovate, often 
as long as the petiole, and nearly as large as the leaflets of 
the leaf. Raceme erect, terminal, stalked, of several rather 
bright, yellow, alternate flowers, about the size of those of 
the Laburnum. Pedicels short, subtended by an oblongo- 
ovate bractea. Calyx ovate, two-lipped, upper lp erect, 
bidentate, lower trifid, reflexed: Vexillum shorter than the 
rest of the petals, having a deep carina, spotted within, 
the sides reflexed. Ala standing forward, oval, covering 
the carina which is nearly of the same shape and very ob- 
tuse. Stamens ten, free, subulate, nearly equal in length. 
Germen linear, very silky: Style short, curved upwards: 
Stigma minute.
