5—6 mm. long, and 4 mm. broad, broadly ovoid to nearly globular, and each female 

 flower correspondingly smaller, stigmas long and projecting, about the same length as 

 the flowers, thus, at any rate to judge from my material, comparatively longer than in 

 the typical species. Catkin-scales about 2 mm. long, narrow below, only above the 

 middle rather suddenly dilated in a fan-shape. The wing of the nut seems to be compa- 

 ratively narrower than in the typical form. 



This form collected by me along mountain brooks, and in moist places in the 

 Altaian, accompanying various species of Salix about the limit of tree vegetation, or even 

 somewhat higher than the limit of conifers. When gathered at the end of July, in part 

 done flowering, and with young fruits.

Occurring scattered along borders of corn-fields, by road-sides, and near settle-

 road between Minusinsk and Ust Abakansk, where it begins flowering at the end of June. 



Distribution: A native of middle and south-western Asia and adjoining portions of 

 Europe. Now in cultivation, or having established itself as an escape from cultivation 

 over the greater part of temperate regions.

 the arctic regions. North America (introduced).
