The specimens collected of this widely distributed and much varying species have 

 mostly rather broad and flat filaments, nearly liguliform, about one third shorter than the 

 petals, with anthers of a brimstone colour. Petals obovate, of a white colour from 2 to 

 2,5 mm. long, 2 to 3 times as long as the sepals. The pedicels are 5 to 8 mm. long. 

 Scape 15 to 20 cm. high, in the upper part markedly glandular hairy. The inflorescence 

 4 to 5 cm. long, ovoid, and with rather widely spreading branches, not unfrequently rect- 

 angularly. Nvimber of capsules 2 or 3. Lowest bract from 0,5 to 0,7 cm. long, linear to 

 lanceolate, the upper ones smaller, from 2 to 3 cm. long, and linear. Length of the petioles 

 3 to 4 times the diameter of the blade, the margins of which are comparatively coarsely 

 indented, generally with from 20 to 25 teeth, measuring about 3 mm. in length and 

 breadth, and the summit slightly pointed. 



In the Altaian, at altitudes of about 2000 m. above sea-level, in moist, moss-clad, 

 shady places, in full flower at the end of .July.

Rather common about the Upper Amyl, in subalpine wooded regions on mountain 

 slopes, etc. as well as in the Altaian, where ascending to altitudes of about 16 — 1700 m. 

 above sea-level, often associated with Betula rolundifolia, Trolliiis asiaticus, etc. Gathered 

 in full flower in second half of July. The specimens collected are completely glabrous, the 

 leaves obovate, the margin crenate-dentate. The petals are of a light red, to 14 mm. long.
