PAPAVERACEAE 



Tax. note. The petals are a sort of brick red, or better a deep apricot color, something like 

 the flesh of a Moorpark, with the light green very short claws bordered above by a small 

 purple spot. The calyx often falls away as a sort of calyptra, instead of as two separate sepals.

 from Cal. seed, Douglas, a form with thicker leaves; the Douglas type at Kew we found to 

 be almost exactly matched by a specimen from Tracy, San Joaquin Co. (Benj. Cobb.). P.

6. ARCTOMECON Torr. & Frem. 



Herbs with a stout tap root. Leaves long-hirsute, crowded toward the base 

 of the plant. Flowers large, white or yellow, solitary or in an umbelliform 

 cluster. Sepals 2 or 3. Petals 4 or 6, round-obovate, in age persisting around 

 the base of the capsule. Stamens numerous, short. -Ovary and subcoriaceous 

 capsule ovoid or obovoid, 3 to 6 (commonly 4)-valved; style shorter than the 

 globular and lobulate mass of 3 to 6 erect and somewhat united stigmas. Seeds 

 rather few, oblong. Species 3, southwest United States. (Greek arctos, a bear, 

 and mecon, poppy, from the hirsuteness.) 



1. A. merriamii Cov. DESERT POPPY. Plants 1 foot high, the stems some- 

 what branched near the base; herbage glaucous; leaves mostly basal, cuneate- 

 flabelliform, petiolate, coarsely toothed at apex, hirsute with long brown hairs, 

 3 to 71/2 lines long, the cauline shorter; flowers l 1 /^ to 2 inches broad, solitary 

 on long naked peduncles; sepals 3, villous; petals 6, white; filaments slender, 

 slightly dilated upwards ; stigmas sessile.

 This species in its tufted habit, in the shape, size, toothing and hairiness of its leaves and in 

 the size and fundamental structure of its flower is remarkably like A. californicum Torr. & 

 Frem. Both species have been little collected. The differences in inflorescence and color seem 

 well established but other presumed differences need further examination,

 Vegas, s. Nev., Fremont; Gray, Proc. Am. Acad. 12:53, pi. 2 (1876). Not thus far collected 

 in Cal.; peduncles leafy-braeted, several to many-flowered; petals yellow; stigma sessile. 



7. ROMNEYA Harv. 



Tall glabrous perennial from a soft woody base, with colorless bitter juice 

 and alternate pinnatifid leaves. Corolla very large, bright white, with frilled 

 petals. Stamens very numerous. Ovary and coriaceous capsule with 7 to 12 

 plate-like placentae, some of which meet in the axis and form partitions. Style 

 none. Stigmas 7 to 12, partly coherent in a ring. Species 1. (The astronomer, 

 T. Romney Robinson of Dublin, friend of Dr. Thos. Coulter, the discoverer of 

 the plant.)
