PAPAVERACE.E. 281 



Pitt. i. 16. Sparsely pilose-pubescent, 1 — 2I2 ft. liigh, letafy below; 

 leaves pinuately parted or divided into acutish toothed or 3-lobed or 

 entire segments: peduncles elongated: corolla 2 in. broad; petals brick- 

 red, with a green spot at the base bordered with rose-red : capsule y^ i^- 

 long or more, clavate-turbinate, 6 — 11-nerved; stigmas sessile and radi- 

 ating, forming a flat cap to the pod; the short valvular openings somewhat 

 quadrate: seeds coarsely and faintly reticulate.— Summit of the Santa 

 Inez Mts. and northward. 



2. 1*. Leiiiiiioui, Greene, Pittonia, i. 168 (1888). Near the preceding, 

 but larger, 1 — 3 ft. high : corolla 1 — 3 in. broad, apparently of a deeper 

 red, the base of the petals green : capsule broader and merely obovate ; 

 stigmas 7 — 10, their lower half sessile and radiant upon the pod, the 

 upper half coherent and forming a conical apiculation. — Mountains of San 

 Luis Obispo Co.; also said to occur in Marin Co. north of Mt. Tamalpais. 



3. P. heterophylluiii, Greene, 1. c; Benth. Trans. Hort. Soc. 2 ser. i. 

 408 (1834), under Meconopsis. Aspect and size of the two preceding, but 

 the segments of the pinnately divided leaves singularly variable upon 

 the same leaf, some linear, others in close juxtaposition oval; stigmas 

 capitate at summit of a distinct and slender style. — Common in middle 

 California, on wooded slopes, and bearing large nodding flowers; or in 

 open fields among growing grain, with small erect flowers; or else these 

 forms represent two species, M. heierophylla and crassifolia, of Bentham; 

 but from his descriptions no one can decide to which plant belongs either 

 name; moreover, we seem not to have any Calif ornian plant with such 

 capsule as is attributed to M. heierophylla in Hooker's plate (Ic. PI. t. 272). 

 In both our forms the pod is as broadly obovoid, and the openings as 

 small and pore-like as in P. Californicum itself. 



2. ARGIEMONE, Tournefort. Stout prickly herbs, with sinuate -pinna- 

 tifid prickly-toothed leaves, and large short-peduncled white or yellow 

 flowers. Sepals 2 or 3, spinosely beaked. Petals 4—6. Stamens 00 ; 

 filaments filiform; anthers linear. Ovary oblong, with 3 — 6 nervelike 

 placentae; stigmas nearly sessile, radiating. Capsule oblong, prickly, 

 1-celled, opening at summit by 3 — 6 valves separating from the parietal 

 ribs. Seeds ovoid-globose, pitted. 



1. A. iiiuuita, Dur. & Hilg. Pac. R. Rep. v. 5. t. 1 (1855): A. hispida, 

 B. & W. Bot. Calif, i. 21, not of Gray. Perennial, stout, erect, 2% ft. 

 high, very glaucous, glabrous under the dense armature of straight, 

 spreading or retrorse white prickles: leaves elongated-oblong, cordate- 

 amplexicaul, sinuately lobed: fl. few, terminal, white, 3 — 4 in. broad: 

 sepals 3: petals 6: ovary densely prickly, the prickles erect. — Widely 

 dispersed in the mountain districts, but absent from the Bay region; 

 quite distinct from A. hispida of the Great Basin, which has a divided
