The .specimens collected are small, willi Ihe solitary scape 1 — 2, rarely to 3 cm. higli. 

 The bracts of the involucre 3 — 7 mm. long, entire, as a rule somewhat longer than the 

 pedicels. 



Scattered on dry, stony declivities on the steppe about the rivers Yenisei and Aba- 

 kan. Most of the specimens already done flowering at the beginning of June, only some 

 few with flowers of a light red. The capsule is of about the same size as the calyx, rarely 

 projecting.

This nice little plant is of rather common occurrence on the islets in the rivers 

 Yenisei and Abakan, especially in somewhat moist meadows, where taken by me in full 

 flower, and partly with ripe fruits, in the second half of June. The leaves are generally 

 about 1 cm. or somewhat more in diameter. 



Distiibution: From the central and eastern Altai, through the southern portions of 

 the governments of Yeniseisk, Irkutsk, Ti-ans Baikal, western Manchooria, and western 

 China.

The leaves are orbicular-rcniform, 5—6 cm. wide, cordate at the base and character- 

 istic in having the lobes i-ather deeply and sharply serrate. The petioles are 5—9 cm. long, 

 and, like the veins on the under side of the leaves, distinctly winged. The specimens are 

 glabrous, some, however, having a few, scattered hairs along the veins on the under side of 

 the leaf; the upper side is always completely glabrous. The scape is of about- the same 

 height as the leaves. The bracts are ovate to lanceolate, always distinctly and in part
