Vesicaria montana Wats. Bot. Calif. 1: 43. 1876, and suppl. 
2: 432. 1880. 
V. occidentalis Wats. Proc. Am. Acad. 20: 353. 1885. 
Physaria montana Greene, FI. Franciscana, 249. 1891. 
Perennial, silvery stellate-pubescent throughout with many- 
rayed stellae, rays forked near the base; caudex more or less 
enlarged, woody; stems decumbent to erect, 1-2 dm. long, 
unbranched; terminal bud remaining undeveloped; radical 
leaves 2-7 cm. long, blade ovate or narrower, tapering gradually 
to the petiole, entire, frequently repand or even sublyrate; 
cauline leaves oblanceolate, entire, 1-1.5 cm. long; petals yellow, 
narrowly spatulate, 9-10 mm. long; filaments linear; fruiting 
inflorescence elongated; pedicels conspicuously sigmoid, 8-12 
mm. long; pods usually erect, sessile, densely stellate-pubescent, 
oblong to obovate, flattened somewhat parallel to the parti- 
tion, compressed at the apex and along the margins, 4-6 mm. 
long; styles 4-5 mm. long; septum entire or perforate, nerved, 
areolae somewhat tortuous; ovules usually 2 in each cell, funiculi 
attached for about one-half their lengths; seeds not margined, 
radical somewhat turned to one side. 
Distribution: northeastern California and adjacent Oregon.

The typical L. occidentalis, as distinguished from the segre- 
gates L. diversifolia and L. Cusickii, possesses stout stems that 
carry even the lowermost pods of the fruiting inflorescence well 
beyond the longest radical leaves. The caudex, although defin- 
itely perennial, is not so densely clothed with leaf bases as is 
diversifolia, due perhaps to a less distinctly alpine habitat.
