Tetraneuris angustifolia sp. nov. 



Cespitose, acaulescent perennial ; leaves narrowly linear-ob- 

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

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

 scape 2—3 dm. high, stiigose ; 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 T. 

 linearis ; but in that species the branches of the caudex are 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.
