36. Calochortus flexuosus Watson. 



Calochortusflexuosus Watson, Amer. Nat., Vol. VII, 1873, p. 303. 



Stem slender, very flexuous or almost decumbent, a foot or so high, 

 branching; bracts linear or lanceolate, 6-15 lines long; sepals oblong-lanceo- 

 late, greenish with a deep purple spot; petals broadly obovate-cuneate, 12 to 

 15 lines long, purple, claw deep purple; gland obscure, purplish yellow, scat- 

 tering glandular hairs above gland; capsule broadly oblong. 



The description given is substantially that of Watson. 



" Southern Utah and Northern Arizona." 



In 1897, the writer received a number of fresh flowers 

 from St. George, Utah, the type locality. They showed 

 the color to be a deep, rich purple (the flowers are some- 

 times white), the markings varying considerably, showing 

 bands or spots on either petal or sepal; scarcely any two 

 of the flowers were alike in this particular. The very flex- 

 uous habit is distinctive. The stems are often even decum- 

 bent ('^creeping" a correspondent has it). Found also in 

 southern Nevada. 



This Calochortus' grows on the hills in red granite soil. 

 Mr. S. B. Parish collected a species in the desert region 

 of Southern California, which he identified as C. flexuosus. 

 This, he writes, grows in tufts of grass in saline meadows. 

 It is, however, hardly probable that the same species grows 

 under such diverse conditions. 



^ 37. Calochortus dunnii, sp. nov. 



Stem not bulbiferous at base, a foot or two high, slender; leaves linear, 

 deeply channeled; sepals ovate-acute, with white scarious margins, a little 

 over one-half the length of the petals, never recurving, light green without, 

 greenish white within, faintly spotted; petals broadly cuneate, as broad as 

 long, rounded above, white, with a reddish brown transverse band above the 

 gland; gland small and round, densely hairy with short matted hairs, short 

 scattering hairs on each side of the gland only ; capsule linear as in C. 

 venustus. 



Described from specimens flowering in the writer's 

 grounds; they were originally coUected near Julian (San 

 Diego County), California, by the veteran naturalist, 

 George W. Dunn, in whose honor the name is given. So
