Lychnis striata sp. nov. 



Perennial with more or less cespitose base ; stems 3—5 dm. 

 high, finely puberulent and more or less viscid above ; basal leaves 

 and lower stem-leaves narrowly oblanceolate, 5-15 cm. long with 

 a more or less distinct petiole ; upper stem-leaves sessile and linear- 

 lanceolate ; inflorescence narrow with erect branches ; calyx 

 densely viscid puberulent, strongly lo-nerved, in fruit somewhat 

 extended by the capsule, 10-12 mm. long and 5 mm. wide; its 

 lobes oblong, obtuse, somewhat scarious-margincd ; petals exserted, 

 about I 5 mm. long; claw long, narrowly cuneate, fully equaling 

 the calyx ; blade short, two-cleft, with obtuse lobes.

 in the exserted petals and the more strongly lo-nerved calyx. It 

 grows at an altitude of 2000-3300 m.
