Scattered in the Amyl valley and between Kalna and Ust Algiac, cspeciallj' along 

 river-banks, where gathered by me in flower about the middle of July. P>ather frequent 

 in the Urjankai countiy; on the rivers Sisti-kem, Bei-kem, Kamsara, and Tara-kem. In 

 the Altaian, on the mountains, it ascends to 16 — 17(K) m. above sea-level. 



Distribution: North-eastern Russia, Siberia, northwards to about 72'j' north lati- 

 tude, northern Mongolia, eastern Asia, Sakhalin, Japan, North America.

This subspecies, found by me in the Altaian, abt)ut llie limil of tree vegetation, is 

 distinguished by being a low shrub, not exceeding a man's height, with much curved 

 branches, and short, smooth year's shoots, only a few cm. k)ng. The leaves are small, 

 ovate, pointed at the summit, and at the base broadly rounded or slightly cordate, length 

 from 2,5 to 3 cm., and breadth towards 2 cm. The leaves are always markedly incised- 

 serrulatc, with fine, acute teeth and are. moreover, distinguished by the midril) being 

 completely smooth underneath and by the absence of tufts of hairs in the angles be- 

 tween the veins on the under sides of the leaves, which are, like the petioles, pedunc- 

 les, and the year's shoot on the whole, more or less densely glandular-hairy. The leaves 

 are always of a pale green and dull colour underneath, bright and glabrous above. 

 Female catkins small, only half the sixe of those of the typical species, generally from
