segments ; petals 2-lobed, erect-spreading ; capsules cylindrical, tapering 

 above, striated, submembranous, the valves septiferous ; seeds oblong, smooth, 

 few (4-6) and in a single series in each cell. — Stems 6-12' high, slightly pu- 

 bescent in these specimens, as also the solitary capsules ; flowers i-1" and 

 capsules 3-4" long. CE. densiflora, Lindl., as recognized, is so exceedingly 

 variable that this comparatively glabrous small-flowered form might perhaps 

 be also included. But the septiferous valves, the very short calyx-tube and 

 the entire absence of tomentum seem sufficiently distinctive. Carson River 

 bottom, near Reed's Station, Nevada; July. (413.) 



CEnotheea scapoidea, Nutt. Annual, glabrous or somewhat pubescent ; 

 stems 3-18' high, simple or branched at base ; leaves mostly near the base 

 of the stem, lyrate-pinnate, the terminal leaflet cuneate or cordate at base, 

 lateral ones often obsolete, ovate or ovate-oblong, acute, denticulate or 

 toothed, the upper leaves small, petioled, or wanting ; raceme somewhat scor- 

 pioid, rather loosely flowered, elongating in fruit, with minute bracts; flowers 

 pedicelled, rather small, yellow ; calyx-tube funnelform, rather shorter than 

 the ovate segments ; petals 1-2" long, obovate, entire ; capsule clavate-cylin- 

 drical, somewhat membranous, 4-nerved, ^-1^' long, exceeding the spreading 

 pedicel ; seeds obovate, ascending, smooth. — Described by Nuttall from very 

 small specimens. Collected by him in the Rocky Mountains, (probably in 

 Wyoming,) and also by Geyer, by Stansbury in Utah, and by Beckwith north 

 of Pyramid Lake, Nevada. Found in the Truckee and Holmes Creek Val- 

 leys, Nevada, in the Wahsatch, and about Salt Lake ; 4,500-6,000 feet alti- 

 tude ; May-September. (414.) 



Var. clav.s;formis. {CE. clavaBformis, Torr. Frem. Rep., p. 314.) 

 Flowers rather larger, .petals 3-4" long, pinkish- white, occasionally with a 

 broad purple spot at the base of the petal, rarely yellowish. — The more fre- 

 quent Nevada form. CE. cardiophylla, Torr., is without doubt the same, and 

 CE. brevipes, Gray, can hardly be more than a form. California and Arizona. 

 Frequent through Nevada from the Washoe to the Toyabe Mountains ; 

 4,500-6,000 feet altitude; May-November. (415.) 



CEnotheea beevifloka, T. & Gr. Perennial, acaulescent, somewhat 

 pubescent; leaves petioled, 2-6' long, lanceolate, acuminate, interruptedly 

 pinnately parted, the segments lanceolate, acuminate, toothed or entire ; calyx- 

 tube marcescent, much shorter than the leaves, filiform, dilated at the sum- 

 mit, the segments lanceolate, shorter than the obovate yellow petals, but
