Northern Chihuahua, New Mexico and Colorado; Saskatchewan, (Bourgeau.) 

 Truckee Valley and West Humboldt Mountains, Nevada; Wahsatch and 

 Uintas ; 5-8,000 feet altitude ; May-July. (410.) 



CEnotheea maeginata, Nutt. Perennial (?,) acaulescent or with a 

 short suberect stem, (2-6' high,) more or less villous-pubescent or nearly 

 glabrous ; leaves petioled, lanceolate, acute, variable in section, runcinate, 

 lyrate, repandly toothed, or nearly entire ; calyx-tube elongated, (3-5' ;) pe- 

 tals large, 1-2' long, obcordate, nearly white, becoming rose-color ; capsules 

 sessile or upon short peduncles, coriaceous, oblong, somewhat attenuate above, 

 straight or curved, sub-4-angled, more or less ribbed, with the ridges tuber- 

 culate or smooth ; dehiscence loculicidal ; seeds nearly horizontal, obovate, 

 smooth, sulcate. — This species must include CE. ccRspitosa and montana of 

 Nuttall, as neither the pubescence, shape of the leaves, length of the calyx- 

 tube and pedicels, nor form of the capsule, affords any constant distinctions. 

 CE. eximia, Gray, is probably but a luxuriant, more than usually caulescent 

 form ; as yet collected only with very immature fruit. . Specimens of un- 

 doubted marginata approach it in size. From Wyoming and Colorado to the 

 Sierras ; New Mexico, (Thurber.) Foot-hills through Nevada and around 

 Salt Lake Valley ; 5,000 feet altitude ; May, June. (411.) 



Var. PUKPUEEA. A subalpine form; canescent with a minute pubes- 

 cence ; leaves lanceolate, acute, or ovate and obtuse, entire or slightly den- 

 ticulate ; the calyx and corolla more or less purplish, even before opening. 

 East Humboldt Mountains, Nevada ; 8-10,000 feet altitude ; July, Au- 

 gust. (412.) 



GEnotheea viminea, Dougl. Annual, nearly glabrous, glaucous ; stems 

 2 3° high, ascending or erect, branched; leaves lanceolate, almost entire, 

 nearly sessile ; calyx-tube funnelform, about equaling the segments ; petals 

 lilac or rose-color, 7-8" long, exceeding the stamens ; filaments flat, unequal ; 

 style exSerted ; stigma-lobes short, oval, purple ; capsules sessile, cylindrical, 

 1' long or more, slightly 4-sided, tapering to the apex, canescently puberu- 

 lent ; seeds ascending, in a single series, with a membranous border. — Cali- 

 fornia. Collected by Stretch in Western Nevada. 



(Enotheea glabella, Nutt. Annual, glabrous or nearly so; stems 

 erect, simple, or branched at base ; leaves sessile, lanceolate or ovate-lanceo- 

 late, acuminate, serrulate ; flowers very small, purple, axillary, sessile, soli-
