PAPAVERACEAE 



sistent placentae. Seeds comparatively few, oblong-, shining and finely lined longitudi- 

 nally. [Name Greek, meaning bear and poppy, from the densely hairy leaves.] 



A genus of three species, natives of the Great Basin region of western United States. Type species, Arc- 

 tomecon califomica Torr. & Frem. 



1. Arctomecon Merriamii Coville. Desert Poppy, Merriam's Bear 



Poppy. Fig. 1903. 



Arctomecon Merriamii Coville, Proc. Biol. Soc. Wash. 7: 66. 1892. 



Stems sparsely branched near the base, about 3 dm. high, glaucous. Leaves mostly basal, 

 6-15 mm. long, cuneate-oblanceolate, flabelliform, narrowed to a winged petiole, coarsely toothed 

 at the apex, truncate, covered with long brown hairs; flowers solitary on the elongated naked 

 peduncles; sepals 3, villous-pubescent ; petals usually 6, white, obcordate, 30-35 mm. long; 

 capsule linear-oblong, 3-4 cm. long. 



Desert slopes, Lower Sonoran Zone; eastern edge of California in Inyo County, east to adjacent southern 

 Nevada. Type locality: a few miles west of Vegas Ranch, Lincoln County, Nevada. April-May. 



Arctomecon calif ornica Torr. & Frem. in Frem. Second Rep. 312. pi. 2. 1845. Characterized by its 

 more numerous flowers on bracted peduncles, yellow petals and glabrous sepals. It inhabits southern Nevada, 

 has not been found in California. The name was applied when the region belonged to Mexico, and the California 

 of that time covered a much larger territory than the present state. 



11. CANBYA Parry ex A. Gray, Proc. Amer. Acad. 12: 51. pi. 1. 1876. 



Diminutive glabrous annuals, with very shortly branched stems. Leaves crowded in 

 a dense basal tuft, alternate, linear and entire. Flowers solitary on very slender axillary 

 peduncles. Sepals 3. Petals 6, deciduous or marcescent. Stamens 6-9. Pistil 3-carpellate ; 

 stigmas 3, radiate, adherent to the ovary; ovary 1-celled with 3 nerve-like parietal pla- 

 centae. Capsule oblong-ovoid, the three valves dehiscing from the placentae; seeds sev- 

 eral. [Name in honor of William H. Canby, an American botanist.] 



A genus of two species, natives of western United States. Type species, Canbya Candida Parry. 



Petals white, persistent and closing over the ovary after anthesis. 1. C. Candida. 



Petals yellow, early deciduous. 2. C. aurea. 



1. Canbya Candida Parry. White Canbya. Fig. 1904. 



Canbya Candida Parry ex A. Gray, Proc. Amer. Acad. 12: 51. pi. 1. 1876. 



Stems short, branched, forming tufts 1-3 cm. high. Leaves fleshy, narrowly linear, 5-10 

 mm. long; peduncles filiform, about 1-2 cm. long; petals pearly white, rounded, 3-4 mm. long, 

 closing over the ovary after anthesis ; capsule oblong-ovoid, 2 mm. long. 



Sandy washes, Sonoran Zones; Mojave Desert, southern California. Type locality: toward the head of 

 Mojave Desert. April-June. 



2. Canbya aurea S. Wats. Yellow Canbya. Fig. 1905. 



Canbya aurea S. Wats. Proc. Amer. Acad. 21 : 445. 1886. 



Stems short-branched, forming rounded tufts 1-2 cm. high. Leaves fleshy, narrowly linear, 

 3-8 mm. long, glabrous or sparingly pubescent ; peduncles very slender, 2-5 cm. long ; petals 

 bright yellow, broadly ovate, 3 mm. long, deciduous; capsule oblong-ovoid, 2.5 mm. long. 



Sagebrush plains, Upper Sonoran Zone; eastern Oregon from Crook County to Lake County, east to 

 Malheur County and probably adjacent Idaho. Type locality: sagebrush plains southwest of Prineville, Oregon.
