BOTANY. 
tube obconic-funnelform, sliorter than the segments, many times shorter than 
the ovary ; petals 1-4" long, yellow, becoming reddish, broadly obovate, 
nearly entire, rather longer than the style and stamens ; stigma capitate ; 
capsules sessile or on very short pedicels, linear, elongated, very narrow, 
somewhat curved ; seeds very small, ovate, ascending, in one row, nearly 
smooth. — Stems 3-1° in length ; leaves i-1' long and ¥' broad ; flowers very 
variable in size ; capsule i-V long, , with the pedicel somewhat adnate to the 
petiole of the subtending leaf. This species doubtless includes CE. parvula 
and epilohioides of Nuttall, contorta^ Hook., striguJosa, T. & G., and probably 
chamenerioides^ Gray. Oregon and Idaho to Cahfornia and Arizona. In the 
Trinity Mountains and Monitor Valley, Nevada, and on Antelope Island, Salt 
Lake ; 5,000 feet altitude ; May-July. (422.) 
Var. Canescent with a short hirsute pubescence ; leaves linear-lanceo- 
late, repandly toothed, sessile ; capsules (immature) sessile. Found in the 
Washoe, West Humboldt and Pali-Ute Mountains of Western Nevada ; 
5-6,000 feet altitude; May, June. (423.) 
CEnotheea pterospeema. Annual, low, more or less hispid-pubescent ; 
stem simple or branched, erect ; leaves oblong-lanceolate, obtuse, entire ; 
flowers axillary, pedicelled, small, pinkish-white ; calyx-tube funnelform, 
shorter than the ovate segments and many times shorter than the ovary ; 
petals obcordate, a little exceeding the calyx, and nearly twice longer than 
the longer stamens ; capsules cylindrical-clavate, nearly straight, attenuate at 
base into a curved pedicel nearly one-half as long, membranous, erect ; seeds 
oblong, ascending, in one series in each cell, flattened and the chalaza bor- 
dered with a spongy somewhat revolute thickening of the testa, minutely tu- 
bercled with cellular processes. — The specimens are all small, but 2-3' high, 
the flowers few and small, with petals 1" in length, the capsule long on 
spreading pedicels ; radical leaves entirely wanting. The character of the 
seed is unusual in this section. Growing under sage brush, Trinity Mount- 
ains, Nevada ; 5,000 feet altitude ; May. Plate XIV. Fig. 4. A plant ; 
natural size. Fig. 5. Capsule ; enlarged two diameters. Fig. 6. Seed. Fig. 
7. Its cross-section ; both enlarged six diameters. (424.) 
CEnothera andina, Nutt. Annual, low, canescently puberulent, branch- 
ing at base ; stems ascending, leaves linear-spatulate, attenuate into slender 
petioles, entire, obtuse ; flowers minute, axillary, yellow, very numerous ; 
calyx-tube funnelform, rather shorter than the segments, many times shorter
