reported from the Altai region either, being said, on the contrary, to be wanting in 

 central Asia, there remains a possibility of a mistake of identity, and I therefore dare 

 only enter it with a sign of interrogation. 



Distribution: Europe, south-western Asia, eastern Siberia, North Africa, North and 

 South America, Australia.

Scattered in thickets between Karatus and Kushabar, and in the subalpine wood 

 regions between the Algiac Pass and Ust Algiac, where I have taken it flowering and 

 in part done flowering about the middle of July. 



Distribution: Southern Siberia from the Ural to Manchoofia and northern Corea, 

 northern Mongolia.

In thickets between Karatus and Kushabar, and of rather common occurrence in 

 the subalpine wooded tracts about the Upper Amyl and about the river Sisti-kem, and 

 at Ust Tara-kem, in grassy and moss-grown places. Nearly past flowering, and with 

 ripe capsules in the second half of July. The lower part of the stem is, in the specimens 

 collected, furnished with dense, spreading hairs, and the upper part with dense, glan- 

 dular hairs. The leaves are pubescent, without glandular hairs. The petals are of 

 the same length as the sepals, or shorter, from 5 to 7 mm. long, acute at the sum- 

 mit, and scarious-margined, viscid-pubescent. The ripe capsules are slightly curved, of 

 about twice the length of the sepals. The peduncles, which are beset with dense, glan- 

 dular hairs, are generally somewhat longer than the calyx. It seemed to agree perfectly 

 with a brachypetaliim f. glandulosum Fenzl. 



Distribution: Europe, Caucasia, Siberia from the Ural to Kamtchatka, Sakhalin, 

 Japan, Russian Turkestan, the Thian Shan, Tibet, India, Ceylon, North America, Green- 

 land.
