In the Altaian, at an altitude of about 2000 ni. above sea-level, especially on moist, 

 shady slopes with a northern aspect, among moss and lichens, accompanying Papauer 

 niidicdulc subspec. xaiillioprlaluiu. Rtinunciilns frigidns. Valeriniui capitala, Alsine arc- 

 iica. etc. In flower and with young fruits at the end of July. All of the specimens collect- 

 ed belong to t gennina Busch, k c. They are large and \'igorous, and agree perfectly 

 with the specimens from Norway, with which I have made a comparison. The petio- 

 le generally considerably longer than the orbicular, ovate, or cordiform blade, the 

 summit of which is either rounded, or sometimes finely subacute. The stem is 2 — 8 cm. 

 long, overtopping the leaves, and generally furnished with a single cauline-leaf. 



Distribution: Arctic Europe and Asia, the Altai, the Sayansk district. Trans Baikal 

 mountains. North America.

Rather common in the territory explored, where especially occurring in dry mea- 

 dows and on mountain slopes. The species is here much van'ing in the form and size 

 of tlie leaves, height of the stem, and floweriness, as well as in the density of the hairs. 

 The specimens generally seemed to be distinguislicd by comparatively long and fine pedi- 

 cels, generally from 1 to 1,4 cm. long about the time of ripening of tlic fruit. The species 

 begins flowering at the end of May. 



Distribution: Europe, the wood and steppe regions of Si])eria, the .\llai, the 

 Sayansk district. Trans Baikal, eastern Asia, North America.
