Veiy common on the islets in the river Abakan, in somewhat moist meadows and in 

 thickets, where the species begins flowering at the end of June. I have also collected the 

 species between Karatus and Kushabar, near list Tara-kem, Ust Kamsara, and with ripe 

 fruits about the middle of August, in meadows at Ust Sisti-kem, where it is of exceedingly 

 common occurrence, together with Gentiana detonsa, Spiraea salicifolia, and others. The 

 specimens vary considerably as to the shape of the leaflets and the length of their stalks. 

 The leaflets are not always opposite, but sometimes alternate. Most of the specimens 

 have very considerable auricles at the base af the leaflets (var. auriculaia Focke in 

 Hallier-Wohlfarth, Koch, Synops. (1891) p. 829). 



Distribution: Europe, the Caucasus and south-western Asia to northern Persia, Sibe- 

 ria, northwards to past 71° north lat, northern Mongolia, eastern Asia, Japan, North 

 America.

Very common in the territory explored, in humid places, in thickets, along brook- 

 sides, and the like. All over the islets in the rivers Yenisei and Abakan, and also in moist 

 places on the banks, where collected with young flower-buds in June. The species is 

 also very common in the Urjankai country, where, on the mountains, ascending con- 

 siderably higher than the limit of tree vegetation, the Algiac Pass, Ust Algiac, the Upper 

 Sisti-kem, Ust Sisti-kem, the Kamsara, the Tara-kem, the Dora Steppe, etc. The species 

 begins flowering here at the beginning of July. All of the specimens are more or less 

 densely white felted on the under side of the leaves (f. tomentosa Ledeb. Fl. Alt. II, p. 

 217). At Ust Algiac I have, besides the above form, collected some specimens distinguished 

 by having the leaves partly glabrous and green underneath. These specimens are also 

 characteristic in having always the peduncles and pedicels completely glabrous as well. 



The dried leaves of this plant are sometimes used by the Soyotes — the natives of 

 the Urjankai country — for smoking, instead of tobacco. 



Distribution: Europe, except the arctic regions, south-western Asia, Turkestan, Sibe- 

 ria, northwards to 68° north lat, northern Mongolia. Introduced into North America.
