1 3. (E. micrantha, Ilornemann. A very variable species closely resembling 

 the last : flowers very small : the petals a line or two long, not spotted at the base, 

 entire or emarginate or sometimes 3-lobed at the summit : capsules 8 to 18 lines 

 long, about a line wide, usually much contorted. — Torr. & Gray, Fl. i. 509. 



From the Lower Sacramento to San Diego. Probably a mere variety of (E. historta. 



* * Flmvers axillary, yellow, often reddish or turning red, mostly very small : calyx- 

 iuhe obconic, very short. 



-K Ca2oside elongated, very narrowly linear, obtusely angled, slightly curved : slender 



leafy annuals. 



14. (E. dentata, Cavanilles. Usually diff"usely branched, a span high or less, 

 more or less liirsute with short spreading hairs especially below, the pubescence 

 above often shorter and somewhat glandular or wanting : leaves linear, sessile, usu- 

 ally narrowed at base, denticulate, \ to 1|- inches long : petals rounded, entire, 2 to 

 4 lines long, rarely reddening : capsules an inch long or more, less than half a line 

 broad, somewhat attenuate at the summit. — Icon. iv. 67, t. 398; Torr. & Gray, 

 Fl. i. 511. 



Var. cruciata, Watson. Petals narrowly obovate to oblong, often emarginate, 

 2 lines long. — Proc. Am. Acad. viii. 594. 



From San Francisco southward ; also in the foot-hills of the Sierra Nevada : less frequent than 

 the following. A Chilian species ; perhaps also Australian. 



15. CE. Strigulosa, Torr. & Gray. Like the last: nearly glabrous, the ovary 

 and calyx usually somewhat appressed-puberulent : leaves entire or sparingly dentic- 

 ulate : petals a line or two long, usually reddening : capsules sessile or upon a very 

 short pedicel adnate to the base of the leaf, abruptly obtuse or scarcely attenuate at 

 the summit. — Fl. i. 512. CE. contorta, Hook. Fl. i. 214. (E. parvida, Nutt. in 

 Torr. & Gray, 1. c. 



Var. pubens, ^Yatson, 1. c. Pubescence hirsute and spreading as in (E. dentata, 

 especially below, often somewhat glandular above and shorter. 



From the Columbia River to San Diego, frequent ; the variety also ranging eastward through 

 Northern Nevada to the Wahsatch Mountains. 



+. +. Cajisule shorter, atteimated iqnvard from the base: dwarf annuals. 



16. CE. andina, ISTutt. Canescently puberulent, only 1 to 3 inches high, 

 l)ranched : leaves liuear-spatulate, entire, attenuate into slender petioles, a half to 

 an inch long : spikes leafy, many-flowered : petals a line long or less : capsules 3 to 

 6 lines long, obtusely angled, somewdurt curved. — Torr. & Gray, Fl. i. 512. 



From Oregon and N. "W. Nevada to Colorado ; i^robably in Northeastern California. 



(E. GuADALUPENSis, AVatson, Proc. Am. Acad. xi. 137, collected by Palmer on Guadalupe 

 Island, is stouter, mth larger oblanceolate leaves, few flowers, and the capsule oblong-pyi'amidal, 

 half an inch long, rather acutely angled. 



* ^ % Flmvers white or rose-colored, in a nodding spike: calyx-tnhe short funnelf arm : 

 capsrde narrowly linear, terete or obtusely angled, much contorted: seeds linear- 

 oblong : annuals. 



17. CE. alyssoides, Hook. & Am. Slender, canescently puberulent: stems 

 simple or branching fn.m the base, erect or ascending, 3 to 12 inches high : leaves 

 oblanceolate or oblong-lanceolate, narrowed into a slender petiole, entire or repand- 

 denticulate, 1 to 2h inches long ; the floral leaves much smaller but similar : si.ike 

 often many-flowered, becoming elongated : calyx-tube 2 or 3 lines long, equalling 

 tlie rounded petals : capsules an inch long or less, very slender, not attenuate 

 upward from the base, puberulent : seeds ash-colored, very minutely pitted. — Bot. 

 IJeechey, 340 ; Hook. Ic. PI. t. 339.
