PAPAVERACE^. 285 



leaves: calyx ovate-acuminate; outer rim of torus narrow, not exceeding 

 the erect inner one, in age closely detlexed: petals 1 in. long or more, 

 deep yellow, shading into orange at base. — Originally from the plains of 

 the Columbia, this i)erfectly distinct species is common in Humboldt Co., 

 perhaps even farther southward on the western side. It is not found at 

 all on the plains, but is in the Sierra as far south as Auburn, Mis,^ 

 Harrison. Late in summer the flowers, reduced to half their si)ring size, 

 are apt to be wholly orange-colored, when the species will be easily 

 confounded with the next. 



3. E. crocea, Benth. Trans. Hort. Soc. 2 ser. i. 407, also Lindl. Bot. 

 Reg. 1. 1677 (1834). Stouter than the last, erect or decumbent, the herbage 

 of a deeper green and scarcely glaucescent: fl. fewer, often strictly 

 terminal: calyx large (1 in. long or more), long-conical; outer rim of 

 torus very broad, more or less undulate: petals 1% — 2 in. long, deep 

 orange throughout. — The most common middle Californian species; 

 abundant in valleys, open plains, and on hillsides in the western parts of 

 the State, in March and April often coloring the landscape for miles with 

 its profusion of orange-colored bloom. The later and reduced flowers 

 are paler than those of spring, whereas in the preceding these are of a 

 deeper color. The buds also of the later and starved specimens of E. 

 crocea lose much of their conical shape and approach those of E. Duug- 

 lasii; but the broad torus-rim of the present species is a constant 

 character ; and while much more abundant than the other in general, the 

 two do not encroach upon each other's territory. 



4. E. glaaca, Greene, Pittonia, i. 45 (1887). Erect or decumbent, 

 very slender, 2 — 4 ft. high, very glaucous: leaf -segments linear, less 

 divergent than in the preceding: calyx slender-conical, varying in late 

 specimens to ovate with slender acumination; outer torus-rim narrow, 

 spreading: petals 1 — 1% in. long, light yellow with a very distinctly 

 rhombic deep orange spot at base. — Species exceedingly well marked by 

 a certain not well definable grace of its very beautiful white-glaucous 

 foliage; discovered by the author on Santa Cruz Island, but found on 

 the mainland in the mountains near Santa Cruz, by Dr. Parry. The 

 dry-season flowers in this species become reduced in size, but undergo 

 no change of color.

5. E. compacta, Walp. Rep. i. 116 (1843); Lindl. Bot. Reg. t. 1948 

 (1837), under Chryseis: E. lenuisecla, Greene, Pitt. i. 169(1888). Annual, 

 erect, 1 — 2 ft. high, glabrous, light green, more or less glaucescent: 

 leaves finely dissected, the ultimate segments linear-cuneiform, 3-toothed 

 or -cleft at the broad apex: calyx very thin and partly diaphanous, 

 slender-conical; outer torus-rim broad, thin: petals % — 1% in. long, 

 light yellow, shading into orange below the middle: segments of coty-
