112 BOTAIST. 



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-l' long and i" 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 (E. parvula 

 and epiloUoides of Nuttall, contorta, Hook., strigulosa, T. & G-., and probably 

 chumenerioides, Gray. Oregon and Idaho to California and Arizona. In the 

 Trinity Mountains and Monitor Valley, Nevada, and on Antelope Island, Salt 

 Lake ; 5,000 feet altitude ; May-July. (422.) 



Yar. Canescent with a short hirsute pubescence ; leaves linear-lanceo- 

 late, repandly toothed, sessile ; capsules (immature) sessile. Found in the 

 Washoe, "West Humboldt and Pah-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 i-%' 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.

CEnotheea 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
