So far found only on Mt. Jefferson, Oregon. 



"Oregon." 



The above was identified for the writer by Baker. As 

 the other varieties which Baker mentions in his "Tulipeae" 

 have been erected into species, and this is more distinct in 

 character than any of them, it seems proper to raise it to 

 specific rank. 



* * Petals with a transverse scale closely appressed over upper portion of 

 gland, ntide or nearly so. Woodland plants; in dry soil. 



10. Calochortus nudus Watson.

 Low and .slender, scape 2 to 4 inches high, with a single leaf 3 to 6 inches

 acute; flowers one or more, in all specimens examined in an umbel if more 

 than one; sepals narrowly oblong-ovate, acute, shorter than petals; petals 

 greenish white or lilac, greenish at base, obovate, somewhat acute, denticu- 

 late al)ove, 5 to 7 lines long, the same in width, entirely nude except for a 

 tuft of two or three short stiff hairs at each extremity of the narrow, closely 

 appressed scale which covers the upper margin of gland; anthers blue, 

 oblong, two-thirds the length of the subulate filaments. 



Probably C. elegans var. subclavatus of Baker. 



On north sides of high mountains in the pine forests of 

 the Sierra Nevada, from Tulare to Plumas counties; in 

 loose dry soils. 



"California (in the Sierra Nevada, Yosemite Valley to 

 Plumas County)." 



The type as described from Tulare County is white, but 

 there seem to be variations tending to lilac, and in some 

 sections a nude petal. This is the smallest flowered of all 

 the Calochorti.
