Cleomella^ parvifloea, Gray. Proc. Amer. Acad., 6. 520. Slender, 

 diffusely branched ; leaflets and the simple bracts hnear ; 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 plocasperma. Low, i-l° high, slender, diffusely branched ; 

 leaflets and the simple bracts linear-oblong ; racemes many-flowered ; flowers 

 small, pale yellow, on filiform pedicels ; stamens equaling the petals ; 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 hke 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. PL 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, petioled, mucronate ; sepals ovate, acute ; petals 

 oval to linear-oblong, shorter than the filaments ; ovary twice longer than the 

 style and several times shorter than the stipe ; capsule retuse, somewhat 



' CLEOMELLA, DC. Sepals distinct, slaort and spreading. Torus short, oblong. Stamens 6, in- 

 curved in jestivation. Pod short, obovate-rhomboidal, 4-8-seeded, with reticulate deltoid or boat-shaped 

 saccate valves, and upon a filiform stipe. Seeds smooth, pitted or variously reticulated ; embryo condu- 

 plioate ; radicle elongated. — Annual glabrous herbs -with stipulate 3-foliolate leaves, entire leaflets, and 

 racemed leafy-bracted yellow flowers. Bbnth. & Hook.
