BOTANY. 
above; stems divaricately branclied, 6-18' liigb, flowers mostly toward the 
extremities of the brandies, ratlier large, the petals exceeding the calyx ; 
stamens usnally all fertile, the shorter varying in length and in the size of 
their anthers ; style longer than the stamens, with a capitate or subclavate 
stigma ; capsules oblong or linear, a little longer than the pedicels. — Flowers 
1 in diameter ; capsules frequently deflexed, 3-6" long ; cells 4-8-seeded. 
Much resembling G. ramosissuntnn , but distinguished by its larger flowers and 
longer capsules. It differs somewhat from G. diffusum as described, but 
the characters of the anthers and stigma are quite variable, and flowers may 
be found that accord well enough with the original. Idaho, Oregon, (Cronk- 
hite,) and California, (4922 and 6371 Bolandcr, 1414 Brewer.) Havallah 
Range and East and West Humboldt Mountains, Nevada, and in the Wah-

CEnotiiera biennis, L. Stems 2-3° high; minutely pubescent, the 
calyx somewhat silky ; spike crowded ; petals 6" in length ; leaves lanceo- 
late, the lower cauline 6' by 1'. Throughout North America from latitude 
56° to Florida, Arkansas, New Mexico, Arizona and California. Wahsatch

Var. GRANDIFLOEA, T. & G. Spike less crowded and with fewer flow- 
ers; petals 1-1 i' long, nearly equaling the tube ; leaves narrowly lanceolate, 
the lower 3' long by h' wdde. Through Nevada and Utah, much more com- 
mon than the last ; 4,500-6,000 feet altitude ; June-September. (406.) 
(Enothera coronopifolia, T. & G-. Perennial, with horizontal root- 
stocks; stems simple, often numerous from a branching base, erect or ascend- 
ing, slender, canescently puberulent, strigose or hispid ; basal leaves linear- 
spatulate, the rest pectinately pinnatifid; throat of the calyx-tube densely 
villous ; petals somewhat orbicular, entire, equahng the stamens, shorter than 
the pistil ; capsule ovate- or linear-oblong, torulose at base, sometimes attenu- 
ate into a very short peduncle, suberect ; seeds large, ovate, turgid, somewhat 
obtuse or obliquely truncate, costate-tuberculate. — Stems 6-18' high ; petals 
nearly white, turning red, i' long ; capsules ^-1' in length. From Northern
