back. — On Table Mountain of the Monitor Range, N. Nevada, at 
10,000 feet altitude ; Prof. C. S. Sargent, 1878. 
Sttene Grayit. Low and alpine (3 to 6 inches high), cespitose, 
grayish-puberulent: leaves oblanceolate, 6 to 8 lines long: flowers 
2 or 3: calyx broadly cylindric, with deep-rounded teeth, 5 or 6 lines 
long : petals rose-color, 7 or 8 lines long, the broad blade bifid to the 
middle with a prominent tooth on each side; claw broad with narrow 
entire auricles ; appendages broad, entire or nearly so: capsule short, 
nearly sessile. — Mount Shasta, near snow; W. H. Brewer, 1862 
(n. 1373) ; Hooker & Gray, 1877; A. S. Packard, Jr., 1877. 
PsORALEA CASTOREA. Stems very short from a tuberous root, 
decumbent; the whole plant covered with white straight closely 
appressed rather rigid hairs: leaves digitately 3—5-foliolate, on stout 
petioles 2 or 3 inches long ; leaflets cuneate-obovate, rounded or acutish 
at the apex, less pubescent above, an inch long; stipules ovate- 
lanceolate, scarious, persistent: peduncles shorter than the petioles: 
spike rather dense, about an inch long, with conspicuous foliaceous 
bracts as long as the calyx (4 or 5 lines), spatulate and abruptly 
acute: calyx-lobes linear, acuminate, nearly equalling the blue petals : 
pod thin, lanceolate, 5 lines long: seed compressed, nearly 2 lines 
long. — Near Beaver City, 8. Utah, on sandy ridges; Dr. E. Palmer 
(n. 96, 1877). Belonging with the next to the P. esculenta group, 
and distinctly marked by the large foliaceous bracts. 
PSORALEA MEPHITICA. A similar species, softly pubescent through- 
out and villous with more or less spreading hairs: leaflets 4 or 4, 
obtuse or retuse: stipules broadly ovate: peduncles about equalling 
the petioles : flowers on very short slender pedicels in a close raceme 
an inch long: bracts mostly scarious, ovate, acuminate or acute, rather 
shorter than the calyx (4 to 6 lines): calyx-lobes linear to oblong- 
lanceolate, lax, equalling the blue petals: pod small, somewhat 
chartaceous, villous above. — Same locality; Dr. E. Palmer (n. 97, 
1877), who describes it as having the odor of the skunk. 
Vicra Revercuont. Annual, pubescent with spreading hairs, the 
decumbent stem angled and narrowly winged, a foot high: leaflets 
3 or 4 pairs on a broad rhachis, cuneate-oblong or the lower obovate, 
rounded or truncate and mucronate at the summit, 4 to 7 lines long: 
flowers solitary, small (3 lines long), light blue, the narrow acuminate 
calyx-teeth about-equalling the tube: pod pubescent, shortly pedicellate 
on a peduncle an inch long or more, 10 to 15 lines long by 2 lines 
broad, 10-15-seeded. — On sandy prairies near Dallas, Texas; J. 
Reverchon, April, 1877.
