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

 have very considerable auricles at liie base af Uic leaflets (var. iiuriciildid Focki: in

Very conmion in the territory explored, in humid places, in thickels, 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 veiy common in (he Urjankai counlry, v^ here, 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 (/'. luiucnlosa Lkdicu. F'I. All. 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 \\A\. 



The dried leaves of this j^lant are sometimes used by the Soyotes — the natives of 

 the Ui jankai country — for smoking, instead of tobacco.
