3. CE. grandipijOEA, Ait. Hort. Kew. ii. 2 (1789) : (1^. biennis, var. 

 grandijiora, Lindl. Bot. Reg-, t. 1604 (1833). Erect, 3—5. ft. high ; stem 

 and inflorescence scabrous and sparsely hirsute ; the ovate-lanceolate 

 denticulate leaves minutely and sparsely pubescent : calyx-tube 1 — 2 in. 

 long, the segments almost as long, their slender tips elongated : petals 

 obcordate, 1}4 — 2 in. long, yellow, turning to deeper yellow : filaments 

 filiform, declined : style shorter than the petals, the linear stigma-lobes 

 }4 in- long, yellow : capsule obtiisely quadrangular, slightly tapering 

 from near the base, the valves with a strong midrib : seeds sharply 

 angled. — Common in cultivation, and sparingly naturalized about Oak- 

 land, Alameda etc. ; differing essentially from (IE. biennis in its annual 

 root, large almost scentless flowers, declined stamens etc. 



•M- ++ Perennial. 



4. (E. arguta. Stems rather slender, decumbent, about 1 ft. high, 

 from a perennial root : herbage puberulent : leaves linear-lanceolate, 

 saliently dentate, 2 — 4 in. long, 3 — 4 lines broad, the cauline broadest at 

 the sessile somewhat clasping base : calyx-tube 1% in. long : petals as 

 long, deeply obcordate, bright yellow turning to orange ; anthers fili- 

 form, about equalled by the style ; stigma-lobes linear, yellow. — In moist 

 places near Monterey, Michener, and southward apparently at consider- 

 able elevations in the mountains. Very distinct from all our annual 

 species of the group. 



-I— -)— Flowers diurnal, ivhile, fading pinkish, nodding in bud; capsules 



sessile, long and narrow; seeds in 1 roiv in the cell. —

5. (E. alhicaulis, Nutt. Gen. i. 245 (1818) ; Pursh, Fl. ii. 733 (1814), 

 excl. descr. ; Nutt. Fras. Cat. (1813), name only. Baumannia NuUalliana, 

 Spach, Phaner. iv. 352 (1835). Stem erect or decumbent, from perennial 

 running rootstocks, simple or branched, 1 — 3 ft. high : herbage glabrous 

 or pubescent, the stem and branches with a smooth shining white bark : 

 leaves linear to oblong-lanceolate, entire, repand-denticiilate, or toward 

 the base pinnatifid, 1 — 3 in. long ; calyx-tube 1 in. long ; tips of the 

 lobes free in the bud : petals white, becoming pinkish, 1 in. long, entire 

 or emarginate : anthers ^4 i^. long, on filiform filaments : capsiile 1 — 1}{ 

 in. long, nearly linear, though slightly tapering from base to summit : 

 seeds terete, 1 line long. — Common along the eastern base of the Sierra 

 Nevada north and south ; a harjdsome species, but the flowers ill-scented. 



6. (E. Callforiiica, Wats. Bot. Calif, i. 223 (1876) : CE. albicaulis, var. 

 Californica, Wats. Proc. Am. Acad. viii. 582 (1873). Perennial and white- 

 stemmed like the last, but low and stout, hoary- pubescent and somewhat 

 villous ; leaves oblanceolate, acuminate, mostly ijetiolate, sinuately 

 toothed or irregularly pinnatifid : fl. larger ; calyx-tube longer, the seg- 

 ments somewhat villous : petals obcordate : capsule 2 in. long, slightly
