568 Rvdberg : Rocky Mountain flora 



mainly in the seeds, which lack the hyaline neck characteristic of 

 that species. From E. glandulosum it is separated by the smaller 

 size of the plant and of the flower, and by the light green leaves, 

 which lack the coarse toothing of that species. It may also be con- 

 fused with E. adenocaulon, but that species has smaller and lighter 

 flowers, propagates by leafy rosettes and has usually distinct 

 although short petioles. E. ovatifolium grows in wet places, espe- 

 cially in springs, in the mountains of Colorado and Utah at an alti- 

 tude of 2,300-3,800 m.

Epilobium rubescens sp. nov. 



Stem 3-4 dm. high, strict and simple, often more or less red- 

 dish, glabrous below, crisp-hairy above and more or less on the 

 decurrent lines ; leaves 3-4 cm. long, perfectly sessile, lanceolate, 

 rounded at the base, denticulate, very acute, slightly crisp-hairy 

 beneath when young ; petals white, about 4 mm. long ; pods 4-5 

 cm. long and 1.5 mm. thick, more or less crisp-pubescent ; seeds 

 without neck, brownish, smooth, about 1 mm. long ; coma white, 

 5-6 mm. long. 



This species is perhaps most closely related to E. adenocaulon, 

 but differs in the perfectly sessile leaves and simpler habit. It 

 grows in wet places up to an altitude of 2,700 m.

Epilobium stramineum sp. nov. 



Stem 5-6 dm. high, simple, light and more or less straw-col- 

 ored, glabrous below, more or less pubescent and somewhat 

 glandular in the inflorescence ; leaves sessile, light green, lanceo- 

 late, tapering at both ends, denticulate, 4-5 cm. long, 1-1.5 cm. 

 wide, very acute ; petals white, 4-5 mm. long ; pod 4-5 cm. long 

 and 1 mm. wide, more or less crisp and glandular ; seeds light- 

 brown, without a neck ; coma white. 



This has been taken for E. Drummondii, but the type of that 

 species has narrow, almost linear leaves, and is seldom over 3 dm.
