teleur. Fl.. IV (1909) p. 167) the main form may also have narrowly lanceolate leaves. 

 Very common on the banks of the Yenisei and Abalcan rivers, and on the low, moist 

 islets in those rivers. Gathered with nearly ripe capsules in the middle of June. 



var. rorida Lackschewitz f. 



The specimens collected are characterized by their stalky catkins, to 1 cm. long, 

 thickly hairy stalks, in so far distinguished from the ordinary var. rorida as the densely 

 long-haired catkin-scales are entire, and not dentate at the base, which is a chief charac- 

 ter in var. rorida. My specimens, therefore, possibly ought to be referred to a var. 

 subpedunculaia. As my material is rather scarce, comprising in all but 4 sheets, probab- 

 ly taken from the same tree, and, besides, 1 have had no opportunity of comparing 

 with the specimens reported by Lackschewitz, I dare not settle this question definitely. 

 The leaves of these specimens are also somewhat broader than those of the material 

 collected, belonging to the typical form, in other respects agreeing well with each other. 



On an islet in the river Abakan, near Askys, on moist banks of rivers. Collected 

 with nearly ripe capsules in the middle of June. 



Distribution: Europe, except the extreme north and south, Turkestan, Afghanistan, 

 western Tibet, the Himalayas, Siberia, except the extreme western portions, eastern 

 Asia, Sakhalin, Japan.

Specimens appearing to be very near the typical Salix viminalis, collected by me 

 on the banks of the Amyl, near Kushabar, and on the Bei-kem, near Tapsa.

My specimens belonging to this subspecies, gathered in several places on islets in 

 the river Abakan, as well as on the banks of that river, agree perfectly with the speci- 

 mens from the Altai in Andersson's herbarium, in the botanical collections of the 

 „Riksmuseum" at Stockholm.
