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, shghtly pu- 
bescent in these specimens, as also the solitary capsules; flowers ^-1" and 
capsules 3-4" long. CE. densiflom, 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 Eiver 
bottom, near Reed's Station, Nevada ; July. (413.) 
(Enothera 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, i-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^FORMis. (CE. clavceformis, Torr. Fran. 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. cardiophyUa, Torr., is without doubt the same, and 
CE. brevipes, Gray, can hardly be more than a form. Cahfornia and Arizona. 
Frequent through Nevada from the Washoe to the Toyabe Mountains; 
4,500-6,000 feet altitude ; May-November. (415.) 
CEnotheka breviflora, T. & G. 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
