 9 to 15 lines long, very broadly obovate and scarcely acute, rather deeply pitted, 

 covered and fringed with long purple and white hairs ; gland without scale, but the 

 upper circular edge with a dense fringe of reflexed hairs : anthers lanceolate and 

 acuminate, 2 or 3 lines long: capsule broadly elliptical, acutish at each end, 10 to

H- -H- Petals hairy only toward the base or wholly naked. 



8. C. nudus, Watson, 1. c. Low and often slender (2 to 10 inches high), with a 

 single elongated leaf 3 to 10 lines broad ; bracts usually small (an inch long or less) : 

 flowers 1 to 6, usually in a single umbel : sepals about equalling the broadly fan- 

 shaped petals, which are 4 to 10 lines long, white or pale lilac, denticulate above, 

 and wholly without hairs ; gland shallow, divided by a broad transverse denticulate 

 appressed scale : anthers linear-oblong, obtuse, 2 or 3 lines long, about equalling the 

 filaments : capsule oblong, acute at each end, 8 or 10 lines long and 4 or 5 wide : 

 seeds yellowish, papillose, with a white vesicle at base. Cydobolhra elegans, var., 

 Benth. PI. Hartw. 338 (n. 1986); Torr. 1. c. Calochortus elegans, var. subcalvatus,

 rather stout, usually branched, with broad elongated leaves (4 to 6 lines wide), and 

 long conspicuous bracts : flowers 4 to 10, in 1 to 3 umbels or close corymbs, on long 

 flexuous pedicels: petals broad, 6 to 12 lines long, pale lilac, with a more or less, 

 purplish claw, somewhat hairy below the middle ; gland very shallow, ciliately mar- 

 gined and with a narrow scale : anthers oblong, obtuse, 1 to l lines long, much 

 shorter than the filaments : stigmas slender : capsule elliptical, obtuse at each end, 

 an inch long. Proc. Calif. Acad. ii. 5 ; Baker, 1. c. 306. C. umbellatus, Wood,

10.. C. uniflorus, Hook. & Arn. Stem low and slender (3 to 6 inches high), 

 1 - 2-flowered : leaves 2 to 4 lines broad ; bracts near the base, elongated : sepals 6 

 to 8 lines long, purplish, sometimes spotted : petals 10 to 12 lines long, the upper 

 margin denticulate, lilac with a purplish base and small very shallow purple densely 

 hairy gland, the lower half of the petal above the gland covered with scattered hairs :

 usually densely hairy : capsule (except in group *) narrowly oblong, with
