 spatulate, short, 6"-12" long; flowers axillary throughout the branches; 

 segments of the calyx about the length of the petals; longer stamens 

 one-third shorter than the petals; capsule linear, 8"-10" long, tapering

 puberulent ; stem low, branches sometimes 1 -2 long ; leaves deeply pin- 

 riatifid, with linear and acute segments, radical ones often nearly entire; 

 flowers axillary, large, 2 / -3 / in diameter ; segments of the calyx rather 

 shorter than the tube and much shorter than the broadly obcordate 

 petals ; style filiform, shorter than the petals, but exceeding the stamens ; 

 stigmas filiform, divaricate, as long as the slender anthers ; capsules 

 prismatic-cylindrical, striate-grooved, somewhat tapering towards the 

 apex, about I 7 long ; seeds 1-rowed in each cell, terete, ascending. Hall 

 & Harbour, 177 ; Brandegee. Clear Creek, Coulter. On the Platte near 

 Denver, Dr. Smith. Wet Mountain Valley, Redjield. 



(ENOTHERA CORONOPIFOLTA, T. & G. Perennial, with horizontal

 or ascending, slender, cauescently puberulent, strigose or hispid ; basal 

 leaves linear-spatulate, the rest pectiuately piniuitiiid ; throat of the 

 calyx-tube densely villous; petals somewhat orbicular, entire, equaling 

 the stamens, shorter than the pistil, nearly white, turning red, \' long ; 

 capsule ovate or linear-oblong, tor ulose at base, sometimes attenuated 

 into a very short peduncle, sub-erect; seeds large, ovate, turgid, some- 

 what obtuse or obliquely truncate. Hall & Harbour, 178; Dr. Smith ; 

 B. H. Smith ; Canby ; Braudegee. Plains around Denver and Colorado 

 Springs, Porter. Plains of the Platte and Pleasant Park, Coulter. 



(ENOTHERA ALBICAULIS, Nutt. Perennial, puberulent or hirsute; 

 stems usually l-3 high, erect or ascending, with a white, membran- 

 ous, shining bark; leaves very variable, linear or lanceolate, attenuate 

 at the base, entire or more or less dentate ; petals round-ovate, more or 

 less unguiculate, entire, exceeding the stamens and equaling the pistil, 

 often nearly white; capsule thickened at base, sessile, linear, divaricate, 

 often flexuous or deflexed; seeds rather small, linear-lanceolate, smooth.

(ENOTHERA TRILOBA, Xutt. Biennial, acaulescent, nearly glabrous ; 



1 GAYOPHYTUM, A. Juss. Calyx-tube not produced beyond the ovary, linear, sub- 

 terete; lobes 4, spreading, deciduous; petals 4, obovate, very shortly* unguiculate ; 

 stamens 8, or 4, alternate, with as many staminodia ; iilaivents short, filiform ; anthers 

 globose ; style rather short, with a capitate or clavate stigma ; capsule small, mem- 

 branous, linear, 2-celled, 4-valved, two opposite valves bearing a narrow dissepiment ; 

 seeds few-many, in a single series in each cell, ascending. Annual, slender, branching
