* Torus broadly rimmed; cotyledons bifid. 

 H- Perennials. 



1. E. Californica, Cham. Glabrous, glaucescent, the stems decum- 

 bent or at length procumbent, 12 ft. long, regularly dichotomous 

 below, above bearing a flower opposite each leaf: leaves ternately 

 dissected, the ultimate segments linear, obtuse: calyx oblong or ovoid, 

 abruptly short-pointed; torus-rim broad: petals about % in. long, light 

 yellow with an orange spot at base : pods small for the size of the plant 

 (2 in. long): seeds conspicuously reticulate. Only along the seaboard in 

 sandy soil. 



2. E. Douglasii (H. & A.), Walp. Size of the last but less depressed, 

 not obviously dichotomous: calyx ovate-acuminate: outer rim of torus 

 narrow, not exceeding the erect inner one, in age deflexed: petals 1 in. 

 long or more, yellow, shading into orange at base. Plains of Solano and 

 Contra Costa counties. 



3. E. crocea, Benth. Stouter, erect or decumbent, the herbage of a 

 deeper green and scarcely glaucescent: calyx very large, often 1 in. long 

 or more, long-conical: outer rim of torus very broad, more or less undu- 

 late: petals, 1% 2 in. long, deep orange. The most common species in 

 our district, and very showy. 



-H- Annuals. 



4. E. compacta, (Lindl.), Walp. Annual erect, 1 2ft. high, glabrous, 

 light green, more or less glaucescent: leaves finely dissected, the ulti- 

 mate 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. Dry plains of Contra Costa Co., and southward, but 

 not in the typical form. 



5. E. ambigna, Greene. Slender, branching from the base, decum- 

 bent, glaucous and scabrous puberulent throughout, 1 ft. high or less: 

 leaves small, ternately dissected, the ultimate segments short, approxi- 

 mate in threes: calyx ovate acuminate, about 4 lines long or 5: torus 

 small, but with ample rim: petals deep yellow, 1 in. long or less. Near 

 the summit of Mt. Diablo (not typical) and southward. 



* * Torus without rim; cotyledons entire; annuals.
