syntype; no. 82° or 93804 O., fr.; stomata superne in foliis non visa); west 
of Martin Point, July 30, 1914, F. Johansen (no. 136* or 93483 O., st.; folia 
superne stomatibus numerosis instructa breviter petiolata, forma porro obser- 
vanda). 
Dr. Frits JOHANSEN has been so kind as to give me the following informa- 
tion regarding this variety: “Nos. 44a, b, Collinson Point. This willow grew 
on more bare, gravelly tundra near the beach (transition region to the latter), 
in patches of several plants. Its growth was very prostrate and depressed 
(among stones and vegetation), with the stems and branches lying very close 
to the ground and spreading widely, so that only the catkins showed up from a 
little distance. Especially the subterraneous parts (roots and stem parts) 
were less extensive and spreading than with those found at Kongenevik, Alaska 
(see below); probably because they did not grow on sand dunes as is the case 
at the former place.—Nos. 82a, b, Kongenevik. The collecting place was 
where the seashore (beach) through low sand dunes goes over into the more 
typical tundra behind. On these sand dunes the vegetation is very char- 
acteristic and consists almost exclusively of Elymus, Carex, Salix, Chamaerium, 
etc.; each species spreading (both above and under the ground) over large 
patches (areas) and dominating more or less to the exclusion of the other 
species. This Salix seemed to be very prostrate, but the larger part of each 
plant is buried in the sand, so that only the leaf and catkin-carrying branch 
parts (outer third) protruded. It was mostly large plants widely spread- 
ing (both roots and stems); the branches often having the form of long 
runners’”’ intersecting the sand rhizome-like in all directions. The sand- 
covered parts of the branches were without leaves or catkins and pale 
(white-yellow). When growing in less sandy soil the growth is naturally 
regions at Collinson Point and at Kongenevik, so did also the growth of the 
Salix in question resemble those of the same species from both of the foregoing 
places. At the time of collecting the plants had dropped ¢ catkins and had 
unripe ° catkins.”
