128 Rydberg : Rocky Mountain flora 



Colorado: Grand Junction, 1894, Crandall (type) ; McCoy's, 

 Eagle County, Osterhout 2737. 



Tetraneuris angustifolia sp. nov. 



Cespitose, acaulescent perennial ; leaves narrowly linear-ob- 

 lanceolate, 4-10 cm. long, 4-5 mm. wide, loosely and sparingly 

 long-villous or glabrate in age, not densely villous at the base ; 

 scape 2-3 dm. high, strigose ; involucre hemispherical ; bracts ob- 

 long, obtuse, densely villous ; disk 10-12 mm. wide; rays about 

 1 cm. long and 4 mm. wide, 3-toothed and conspicuously 4- 

 nerved. 



This species is nearest related to T. scaposa, from which it dif- 

 fers in the narrow leaves. It has therefore been mistaken for T. 

 linearis ; but in that species the branches of the caudexare rather 

 slender and elongated and the leaves are narrowly linear, 1-2 mm. 

 wide. T. angustifolia grows on rocky hills up to an altitude of 

 2000 m.

Stout, usually with broader leaf-segments or leaves ; heads 

 larger, 3-5.5 mm. in diameter; outer bracts longer, lanceolate or 

 linear-oblong, mostly acutish, nearly equaling the inner (in A. 

 dracuneitloides oblong, obtuse, about half as long as the inner).
