Scattered in peat-bogs, and the like, in the Amyl valley, at Ust Algiac, Ust Kamsara, 

 and in the Altaian, where collected by me at altitudes of to about 20(X) m. above sea-level, 

 with young flowers at the end of July. The specimens agree perfectly with var. li/pica E. 

 BuscH, 1, c. 



Distribution: Noilliern and middle Europe, southwards to France, Switzei4and, and 

 Austro-Hungary, Siberia, northwards to the mouths of the rivers Yenisei, Lena, and

Rather common in the Altaian, near the sources of the river Sisti-kem, at an alti- 

 tude of about 2000 m. alcove sea-level, mostly on somewhat dry cliffs covered with mosses 

 and lichens, where gathered by me with young fruits at the end of July. 



Distribution: Arctic and alpine regions of Europe, nortliei-n Siberia, approximately 

 between 65° and 72° -noiUi lat., eastwards to Kamtchatka, the Thian-Shan, the Altai 

 and the Sayansk districts, northern Mongolia. Baikal, Trans Baikal, the Amoor Province, 

 Sakhalin, Japan, Noilh America.

Common in peat-bogs, and the like, in subalpine and alpine regions of the Sayansk 

 district. I have collected and observed it in the following places: Kalna, Ust Algiac, in 

 the Altaian up to the bare' mountains, near Tshebertash, and near Utinski porog. 



Besides the typical plant, /. viilgare A. Bl., there also commonly occur specimens 

 of /. miciocarpum Tirczan. Both of these forms are frequently found growing togethej- 

 and — in point of morpholog}' — they are not strictly separated, but connected together 

 by intermediates. The species flowers in July. The specimens collected agree perfectly 

 in structure with Scandinavian material of comparison.
