Cleomella^ pakviploea, Gray. Proc. Amer. Acad., 6. 520. Slender, 
diffusely branched ; leaflets and the simple bracts linear ; flowers small, on 
elongated filiform pedicels ; pod obovate-globose, the stipe scarcely exceeding 
the calyx, and the style very short ; seeds smooth. — 3-8' high, with very small 
flowers, (the petals and equal stamens about J" in length,) and with capsules 
about IJ" in diameter. Collected by Anderson near Carson City, and by 
Cooper near Fort Mohave in Western Arizona. In wet subalkaline soil 
on Dry Creek, Monitor Valley, Nevada; July. (134.) 
Cleomella plocaspeema. Low, ^-1° high, slender, diffusely branched ; 
leaflets and the simple bracts linear-oblong ; racemes many-flowered ; flowers 
small, pale yellow, on filiform pedicels ; stamens equaling the jietals ; pods 
somewhat 2-horned, shorter than the stipe ; style short ; seeds oblong-ovate, 
mottled brown, tessellated under the microscope. — Very near the last and also 
to C. Mexicana, but distinguished from both by the seed especially, which is 
more ovate, (a half longer than broad,) the surface finely marked like parti- 
colored braid-work. The flowers are twice larger than in the last and more 
densely racemed, and the broader capsule is upon a stipe 2" in length. Near 
the Hot Springs in Ruby Valley, Nevada; September. It is also 28 Torrey, 
from sterile saline plains, Humboldt County." C. angustifolia, Torr., of 
Texas and Colorado, (distributed in the Colorado collections by mistake under 
the name of C. tenuifolia,) has a rugose seed of similar shape. In authentic 
specimens of C. Mexicana, the pods are less prominent at the apex or even de- 
pressed with the horns projecting forward, the short style usually deciduous ; 
seeds bluntly ovate, almost globular, and nearly smooth ; flowers as in the 
present species. (135.) 
Cleomella longipes, Torr. PI. Wright. 1. 11. Leaflets spatulate-obovate 
or narrowly oblong, obtuse or retuse, entire or serrulate-scabrous upon the 
margins, shortly mucronate; racemes usually many -flowered, becoming elon- 
gated; upper bracts simple, petiolcd, mucronate; sepals ovate, acute; pdals 
oval to linear-oblong, shorter than the filaments ; ovary twice longer than the 
style and several times shorter than the stipe; capsule retuse, somewhat 
1 cleomella, DC. Sepals distinct, short and sproading. Torus short, oblong. Stanit iis (!, in- 
curved in aistivation. Pod short, obovate-rhomboidal, 4-8-8eed('d, with reticulate deltoid or boat-sh.iiK d 
saccate valves, and upon a filiform stipe. Seeds smooth, pittcil or vurioiisly reticulated ; euibiyo coiidii- 
plicate; radicle elongated.— Annual glabrous herbs witli stipulate 3-Miolato leaves, entire leallets, and 
racemed leafy-bracted yellow flowers. Bextii. & Hook.
