1. D. rigida Benth. Bush Poppy. Two to 4 (or 7) ft. high, the main 

 stem bark shreddy; branches whitish; leaves yellowish green, oblong- to linear* 

 lanceolate, reticulate, hispidulous on the margin, mucronate, 1 to 2 in. long,

 1 to 2% in. in diameter, on peduncles 1 to 3 in. long; sepals orbicular; capsule 

 curved, 2 to 4 in. long. 



Dry slopes and ridges of the Coast Ranges at middle altitudes from Lake

4. ESCHSCHOLTZIA Cham. 

 Annuals or perennials with watery juice, petioled ternately dissected leaves 

 and peduncled yellow flowers. Receptacle hollowed or excavated, surrounding 

 the base of the pistil, the calyx or corolla in consequence seeming as if perig- 

 ynous; this receptacle in addition often bears a spreading outer and an 

 erect inner rim. Sepals completely united into a calyptra or pointed cap- 

 like body which parts from the receptacle and is pushed off by the expanding 

 petals. Stamens numerous, mostly on the base of the petals; anthers com- 

 monly longer than the filaments. Ovary linear; style very short; stigmas com- 

 monly 4, subulate-filiform, unequal. Capsule 1-celled, many-seeded, 2-valved; 

 dehiscence commonly occurs after the capsule parts from the receptacle and 

 before it reaches the ground, usually beginning at the moment that the base 

 of the capsule is released from the vise-like hollowed receptacle, this action 

 allowing the valves which are elastically dehiscent from base to apex, to sep- 

 arate. (Collected at San Francisco in 1816 by Adelbert von Chamisso, Ger- 

 man poet and naturalist, and named by him in honor of his college friend and 

 companion on a scientific voyage around the world. Dr. J. F. Eschscholtz.)
