*/ 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 

 I 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 7T 

 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.
