140 . Muhlenbergia, Volume 3 
length: style 3mm. long: mature capsule 6mm. long, densely 
covered with long hairs, abruptly attenuate at apex, 8-nerved: 
seeds concave on the inner surface, about 1mm. long, glabrous, 
slightly narrowed at one end. 
Allied to B. densiflora, but about one-half the size in all its 
parts with a few linear-lanceolate leaves below, and only broadly 
ovate leaves above subtending the flowers. 
The type is deposited with the Nevada Agricultural Exper- 
iment Station herbarium, and was collected at Maggie Creek, 
Elko county, Nevada (No. 644) P. B. Kennedy, August 13, 1902. 
Chylisma venosa n. sp. 
Annual or biennial, with a stout tap root: plant villous- 
hirsute, becoming glabrous towards the inflorescence, 4 to 8 dm. 
high: leaves mostly produced from or near the base, 1 to 2dm. 
long, unequally and irregularly pinnate, terminal segment or- 
bicular-ovate, many times the size of the lower segments, light 
gray (canescent) above and prominently brown-veined and short 
hirsute below, segments irregularly serrate or lacerate-toothed: 
calyx tube narrowly obconical, 2.5mm. long, calyx lobes lan- 
ceolate, 7mm. long and 2mm. wide: petals yellow, becoming 
purple, orbicular-obovate, about 8mm. long and 6mm. wide: 
style about 7mm. long, hairy at base; stigina globose: anthers 
versatile, 4mm. long, as long as the yellow filaments: capsu’e 
almost glabrous, 20mm. long, gradually tapering to a pedicel 
8 mm. long; seeds ovate-acuminate, 1 mm. long. 
Allied to C. mudltgyuga, but the plant is villous-hirsute and 
the leaflets very unequal, with the terminal leaflet obtuse and 
very much larger than the lateral ones. 
The type was collected on sandy washes and canyons in 
Muddy valley, Lincoln county, Nevada, on May 16, 1906, by P. 
B. Kennedy and I,. N. Goodding, (No. 64). 
No. 5188 collected by Marcus E. Jones at La Verken, Utah,
