PAYSON—MONOGRAPH OF THE GENUS LESQUERELLA 225 
51. L. Cusickii Jones, Contr. Western Botany 12: 2. 1908. 
Annual or short-lived perennial, densely stellate-pubescent 
throughout, stellae many-rayed, rays forking near the base, dis- 
tinct or irregularly coherent; stems numerous, unbranched, 
4-20 em. long; terminal bud remaining undeveloped; radical 
leaves 2-6 cm. long, blade suborbicular, ovate or broadly ob- 
lanceolate, entire or repand, frequently abruptly narrowed to 
the slender petiole; cauline leaves 1-2.5 cm. long, entire or re- 
pand, oblanceolate; petals yellow, narrowly spatulate, 7-8 mm. 
long; filaments linear; fruiting inflorescence elongated; pedicels 
horizontal or even recurved, conspicuously sigmoid, 6-14 mm. 
long; pods sessile, erect to horizontal, densely stellate-pubescent, 
suborbicular to obovate, somewhat flattened parallel to the 
septum, compressed at the apex and on the margins, 4-6 mm. 
long; styles 2-4 mm. long; septum entire, nerved, areolae some- 
what tortuous; ovules 2 in each cell, funiculi attached for about 
one-half their lengths; seeds not margined. 
Distribution: Oregon. 
Specimens examined: 
Oregon: Fossil, Gilliam County, May 30, 1894, Leiberg 130 
(U. S. Nat. Herb., Rky. Mt. Herb., and Mo. Bot. Gard. Herb.); 
white clay hills of Willow Creek, Malheur County, May 3, 
1900, Cusick 2367 (U. S. Nat. Herb., Rky. Mt. Herb., and Mo. 
Bot. Gard. Herb.); banks of Otis Creek, Malheur County, 
June 20, 1896, Leiberg 2337 (U. S. Nat. Herb.). 
L. Cusickii, although agreeing with occidentalis in the eharac- 
ters of the pods, is definitely separated from it and diversifolia 
by the short-lived root. It apparently occurs only on white 
clay soils at a low altitude and to most of the herbarium speci- 
mens the white soil still adheres.
