NEW PLANTS OF THE PACIFIC COAST.—L 
By Tuomas Howe. 
Thermopsis gracilis. Erect, slender, 1 to 3 feet high, with 
spreading branches; sparingly strigose-pubescent through- 
out, at least when young: stipules broadly ovate to lanceolate, 
usually acute: leaflets an inch or two long, cuneate-oblanceo- 
late: racemes short, few-flowered and lax; bracts ovate, acute, 
mostly shorter than the pedicels: calyx-teeth triangular; the 
upper lip truncate or barely 2-toothed: pod appressed-silky, 
2 inches long, 2 lines wide, spreading or somewhat recurved, 
5 to 10-seeded. 
Mountains of southwestern Oregon, from the sources of 
the Willamette River, to northern California. 
Thermopsis robusta. Stout, 4 to 6 feet high ; densely 
tomentose throughout: stipules large, broadly ovate to orbic- 
ular, acuminate, exceeding the petioles: leaflets 2 or 3 inches 
long, rhombic-ovate, acute at each end; raceme elongated and 
dense; bracts ovate-lanceolate, acute, longer than the pedicels: 
ealyx-teeth acuminate, the upper lip notched: fruit unknown. 
In the Californian Coast Range, near the Oregon boundary; 
obtained in June, 1884, and not yet reported from elsewhere. 
Lupinus mucronulatus. Perennial, stems decumbent, 2 
to 6 inches long, the leaves 2 or 3 only; pubescence short and 
appressed ; stipules subulate: leaflets 6 to 10, obovate to 
oblanceolate, obtuse or acutish, mucronulate, an inch or two 
long, sparingly hairy on both sides, or glabrous above ; 
peduncles equalling the leaves: racemes 2 or 3 inches long, 
rather dense; bracts setaceous; flowers subverticillate, purple 
or ochroleucous: upper lip of calyx acute, entire, the lower 
longer, narrow, subentire: petals 4 or 5 lines long, equal; 
keel faleate, ciliate above the middle. 
Species peculiar to the serpentine formation on the eastern 
side of the Coast Range near Waldo, Oregon. Its nearest 
relation appears to be the Alaskan L. arcticus. : 
Eryruza. Vol. I, No. 5 [1 May, 1893].
