Stem,s rather stout, strict, 3-5 dm. high, glaucous. 

 Leaves several, linear, revolute becoming recurved, 

 5-10 cm. long; bracts similar, equalling the very 

 stout pedicels ; flowers usually 2, campanulate ; 

 sepals lanceolate long-acuminate, 35-45 mm. long, 

 with broad scarious margins, tinged with purple 

 within ; petals obovate, 30-45 mm. long, acute or 

 acuminate, purple with yellow base, with a prom- 

 inent green band down the middle, sparsely clothed 

 with yellow hairs on both sides of the gland and 

 for a short distance above ; anthers lanceolate, but 

 obtuse, 10-12 mm. long; capsule lanceolate, 45 mm. 

 long, 8 mm. thick, very narrowly winged. 



Dry plains and hillsides. Upper Sonoran and Transition 

 Zones; British Columbia to Montana and northern Cali- 

 fornia. In the Pacific States it is east of the Cascade 

 Mountains e-xtending from Washington to Modoc Coimty, 

 California. Type locality: "dry barren grounds around the 

 Great Falls of the Columbia and on the summit of the low 

 hills between them and the Grand Rapids."

 Calochortus e.vcavatus Greene, Pittonia 2: 71. 1890.

 Calochortus cajuf>estris Davids. Bull. S. Calif. Acad. 14:

 12. 1915. 



Stem simple, 2-4 dm. high. Leaves very glaucous, some- 

 what fleshy, narrowly linear, 10-15 cm. long, the cauline 

 1 or 2, deeply channelled and more or less recurved ; umbel 

 2-4-flowered ; sepals ovate-lanceolate, about two-thirds the 

 length of the petals, erect or the tips slightly recurved, 

 broadly scarious-margined, usually with a conspicuous dark 

 purple spot (sometimes two) near the base; petals cuneate- 

 obovate, 25-35 mm. long, obtuse or abruptly acute at apex, 

 white tinged with purple above and often down the middle, 

 dark purple around the gland and on the claw ; sparsely 

 hairy around the glands or entirely naked, the hairs yellow- 

 ish with dark purple bases ; gland rounded, yellow, deeply 

 impressed ; anthers yellow, oblong, obtuse, 10 mm. long, 

 exceeding the filaments; capsule lanceolate, attenuate above 

 the middle, 4—5 cm. long. 



Dry gravelly slopes and ridges, Upper Sonoran and Transition 

 Zones: eastern Washington to the eastern slopes of the Sierra Ne- 

 vada and the mountains of southern California, east to South Dakota 

 and New Mexico. Type locality: Salt Lake Valley. Utah. A 

 variable and perhaps composite species as here treated. The south- 

 ern California plants are more slender with a less depressed gland 

 and yellow anthers. Calochortus excaz-atus Greene has a deeply de- 

 pressed puriile gland and purple anthers, and is probably worthy of 



at least varietal distinction. 



30. Calochortus davidsonianus Al^rams. 

 Davidson's Mariposa. Fig. 1086. 



Stem simple or usually branched, 3-6 dm. high, 

 not bulbiferous at base. Basal leaves usually 2 -ir 

 3, about 10 cm. long, 4-6 mm. wide ; flowers termi- 

 nating the branches, or appearing in 2-flowered um- 

 bels ; calyx lanceolate, long-acuminate, recurved, 

 usually nearly equalling the petals, lavender on the 

 inner surface with purple spots near the base ; petals 

 broadly fan-shaped, 25^5 mm. long, rounded at apex, 

 lilac-purple to the very short deep purple claw, 

 sparsely hairy over the lower third with yellowish 

 somewhat tangled hairs: gland (sometimes wanting) 

 obovate, covered with short glutinous hairs ; anthers 

 oblong, obtuse, purple, 4-6 mm. long, shorter than the 

 dilated deep purple filaments ; capsule linear 5-6 mm. 

 long, 5-6 mm. wide, attenuate at apex. 



On grassy or chaparral-covered hillsides. Upper Sonoran 

 Zone; Santa Barbara to .San Diego Counties. Type: grassy 

 slopes between the Onofre Mountains and the sea, San 

 Diego County, Abrains 3275. 1903.
