MEMOIRS OF THE XEW YORK BOTANICAL GARDEN. 307 



* Dodecatheon uniflorum. 



Scape seldom over 5 cm. high (in one specimen 10 cm.), puberu- 

 lent, i-flowered (in one specimen 3-flo\vered), from a short root- 

 stock and a cluster of fibrous roots ; leaves spatulate or oblanceolate, 

 obtuse, nearl}^ without a petiole, densely puberulent ; bracts short, 

 ovate or lanceolate, about 2 mm. long ; calyx-lobes linear-lanceolate, 

 2-3 mm. long : united part of the corolla yellow, with or without 

 a dark purple wavy line ; lobes dark bluish purple, oblong, about i 

 cm. long ; united filaments fully 2 mm. long, orange ; anthers 3 mm. 

 long, dark purplish blue on the back and with yellow sides ; the 

 connective triangular-lanceolate, acuminate ; capsule cylindric, 6-10 

 mm. long and 4 mm. in diameter, splitting into 5 valves. 



Differs from D . fuhesccns in the less distinct petiole, but especially 

 in the form of the stamens. In the color of the flower and the form 

 of the stamens it is strikingly like D. ^aucijiorum^ and may be mis- 

 taken for a depauperate form of it, but in that species the leaves are 

 always glabrous, much longer, and with a distinct petiole. It grows 

 on the sides of the higher mountains, at an altitude of 2500-3000 m., 

 sometimes with D. paucifonivi.
