110 ERYTHEA. 
Lupinus saxosus. Perennial, stems decumbent or ascend- 
ing, 4 to 10 inches long, soft-pubescent with spreading hairs; 
stipules subulate: leaflets 8 to 12, densely appressed-silky, 
sparsely pubescent above, $ to 1 inch long, acute or obtusish: 
raceme dense, 2 or 3 inches long, short-peduncled ; bracts 
lanceolate, acuminate, caducous: flowers subverticillate, on 
short slender pedicels: upper lip of calyx bifid, the lower 
little longer, trifid: petals equal, 4 inch long, the banner 
glabrous and keel ciliate: pod villous: seeds 4 or 5. 
On high stony ridges, from near the Dalles eastward, in 
Oregon and Washington. 
Lupinus canescens. Root thick, perennial; stems stout, 
strict, 2 or 3 feet high, at length branching: leaflets 8 to 12, 
lanceolate, acuminate, 1 to 3 inches long, densely appressed- 
villous on both sides; inflorescence hirsute: raceme dense, 8 
to 10 inches long, short-peduncled; bracts subulate, somewhat 
persistent, about equalling the calyx; flowers subverticillate, 
on stout pedicels 1 line long or more; upper lip of calyx 
toothed, lower nearly entire; petals 4 lines long, the rather 
broad banner pubescent exteriorly; keel shorter than the 
wings, ciliate 
Collected i in June, 1885, at the western base of Buck's 
Mountain, a spur of the Blue Mountains of Oregon; distri- 
buted as n. 787 of my collection of that year. 
Trifolium Oreganum. Perennial; stems decumbent or 
ascending; herbage glabrous, or the petioles and peduncles 
appressed-silky; stipules linear, or the upper ones lanceolate, 
acute, entire, or serrate above the middle: leaflets linear- 
oblong to lanceolate, 4 to 1 inch long: flowers in loose some- 
what umbellate heads, the short pedicels reflexed in age: 
calyx-tube minutely villous, the subulate-setaceous teeth 
twice longer: ovary stipitate, glabrous, 3 to 4-ovuled. 
Rather common near Waldo, in southeastern Oregon, 
flowering in early spring. From the description in the 
Botany of the California Geological Survey I take this to be 
the T. longipes of that work; but it is easily distinguished 
from that species by its weak decumbent stems, large loose
