deeply channeled; plant very glaucous, as in most desert species; inflores- 

 cence umbellate or at least the larger divisions of stem so; umbels, or branch 

 divisions, subtended by three or four lanceolate bracts an inch or two long; 

 sepals ovate-lanceolate, acute, considerably shorter than petals, yellowish 

 green within; petals obovate-cuneate, short clawed, rounding above or 

 abruptly acute, smoky white, claw purplish; gland small, oblong, densely 

 hairy with matted hairs, yellowish short tangled hairs above gland; anthers 

 2-3 lines long, not equalling filament; capsule 3-4 lines broad in the middle, 

 tapering both ways. 



The description given is drawn from specimens taken at 

 Bear Valley (San Bernardino County), California, 



"Higher mountains to the westward of the Mojave 

 Desert." 



C. invenustus was discovered by the namer, Professor 

 Greene, near Tehachapi. It is also found in the Tejon 

 Mountains, and doubtlessly grows all along the line from 

 there to Bear Valley. Specimens from the former locality 

 are identical with those here described. 



The characteristics of the species place it between C . 

 nuttallii and C. splendens. The prominent offset, stiff, 

 stout stem, and tendency to flower in umbels, are strongly 

 suggestive of C. nuttallii, while the flowers resemble those 

 of C . splendens var. montanus.

Calochortus excavatus Greene, Pittonia, Vol. II, 1890, p. 71. 



Resembling the last [C invenustus], but the bracts ovate-lanceolate, scar- 

 ious almost to the striate-veined middle portion, their acuminate tips re- 

 curved; petals white shaded with lurid purple above, but dark purple below 

 and about the broad obovate hairy gland, which is deeply impressed, appear- 

 ing like a yellow saccate body on the outside of the petal; stamens as in the 

 last, but anthers dark maroon. 



"From Bishop Creek, Inyo County, California, collected 

 by Mr. W. H. Shockley (No. 427)." 



Having little knowledge of this species, the writer has 

 quoted the original description and locality of Professor 

 Greene. From specimens seen, the species would seem to 

 come between C. invenustus and C. nuttallii.
