from 5 to 6 mm. long, f. parvifolia Wimm.-Grab. F1. Siles. II (1829) p. 266. Besides, I 

 have also found the species to be ratlier frequent in the Urjankai country, for instance 

 near Ust Sisti-kem, the Kamsara, and Ust Tara-kem. 



Distribution: Nearly all over Europe, except the extreme south, Siberia, northern 

 Mongolia, eastern Asia, North America, Greenland.

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

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

 nudicaule subspec. xanihopetalum, Ranunculus frigidus, Valeriana capitala, Alsine arc- 

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

 ed belong to f. genuina Busch, 1. c. They are large and vigorous, 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 varying in the form and size 

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

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

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

 begins flowering at the end of May. 



Distribution: Europe, the Avood and steppe regions of Siberia, the Altai, the 

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

Scattered on dry, rocky dechvities on the Abakan Steppe, near Ust Kamuishto, 

 where collected by me, flowering and with partly ripe fruits in the second half of June.
