136 CALIFORNIA ACADEMY OF SCIENCES. [Proc. 3D Ser. 



or acute, with white scarious margins, vermilion inside, often spotted brown 

 near base, brownish without; petals cuneate, rather truncate, 10-15 I'nes long, 

 not quite as broad as sepals, a dazzling vermilion, naked above, a few scat- 

 tering hairs below; gland small, round, densely matted with short hairs and 

 bordered nearly black; filaments one-half as long as the oblong-ovate, obtuse, 

 brownish purple anthers, which are 3-4 lines long; capsule xYz-i in. long, 4-5 

 lines wide, attenuate above. 



Found in the arid regions of southeastern California from 

 near the Ojai Valley (Ventura County) and Tehachapi 

 Station, along the eastern flank of the southern continua- 

 tion of the Sierras into San Diego County, eastwardly to the 

 Argus Mountains in southwestern Nevada, and throughout 

 Arizona. 



" Kern County, California." 



In California the flowers are a vermilion color, in Arizona 

 and Nevada, orange. While the stem may reach eighteen 

 inches in height, it often hardly rises above the ground, and 

 the meager ashy foliage gives little promise of the dazzling 

 flower. It is probable that in eastern Arizona and in Nevada 

 C . kennedyi will be found merging into C . aureus.

Calochortiis aureus Watson, Amer. Nat., Vol. VII, 1873, p. 303. 



Low, 4-6 inches high, with a single linear carinate radical leaf, 3-4 inches

 lunate purplish spot above it; young capsule narrowly oblong, not winged. 



" On sand-cliffs, Southern Utah." 



The writer has no acquaintance with the species except 

 as scant herbarium specimens. The description and local- 

 ity are the original of Watson. 



Group 6. Butterfly Tulips. 



Petals slightly hairy below, usually oculated and brilliantly colored; gland 

 prominent, round or lunate; stem bulbiferous at base, erect, slender, 

 branching; radical leaves, usually a pair, channeled, linear, slightly glaucous, 

 not ashy blue as in the desert species; cauline leaves and bracts narrow.
