CONTRIBUTIONS FROM THE ROCKY MOUNTAIN 



• HERBARIUM. VIII 



A vex Nelson 



In 1905 Mr. Leslie N. Goodding again made some collections 

 in the deserts of southern Nevada and adjacent Arizona. These 

 plants, like those of his collections of 1902 and 1903, were deposited 

 with the Rocky Mountain Herbarium at the University of Wyoming, 

 to be named and distributed. Interesting as the earlier collections 

 proved, these which came from even more inaccessible places and 

 from regions which represent the extremes of aridity and heat are 

 equally so. I submit herewith descriptions of the new species and 

 notes upon others that are but little known or that seem to need 

 generic differentiation. 



PLANTAE GOODDINGIAXAE 



Calochortus comosus, n. sp — Glabrous : bulb small, 8-i2 mm in 

 diameter, covered with dead sheathing flaky scales which also invest 

 the base of stem: stem very slender, slightly flexuous, 1-2 dm high, 

 1 (rarely 2)-flowered: leaves narrowly linear: sepals lance-linear, 

 as long as the petals: petals pale lavender or lilac, with darker lines, 

 but not marked with spots or bands of other colors, broadly triangular- 

 ovate, i8-25 mm long; the apex subtruncate, slightly undulate-den- 

 tate; the gland large, ovate, inordinately densely long-bearded with 

 yellow hairs which are glandular- thickened toward the apex; similar 

 hairs are scattered over all the lower half of the petal: anthers white, 

 acute, 7-8 mm long; the filament as long: capsule acute-angled.
