of the denser coniferous growths. About the forest openings it 
is usually associated with Rubus spectabilis and Vaccinium ovali- 
folium. (No. 5.) 
Cladothamnus pyrolacflorus Bone. 
Clusters of this shrub were found growing about the margins 
of tundras and on low ridges. Nowhere, however, was it found 
in any considerable quantity. During the latter part of July 
in the vicinity of Hanning Bay, Montague Island, the bushes 
were covered with blossoms. (No. 2.) 
Vaccinium ovalifolium Smith. Common Huekleberry. 
One of the most abundant and widely spread shrubs of the 
region. It is an important component of the forest undergrowth, 
in some loealities occupying the available ground exclusively. 
At timber-line it is associated with the salmonberry. About 
the snow-slides it grows in considerable beds, taking possession 
of denuded areas and fighting the snow for existence in the same 
manner as the salmonberry. About these inhospitable slopes it 
is found late in the season just budding and flowering at a time 
when the bushes at lower altitudes are ripening their fruit. (No. 
13.) 
Vaccinium uliginosum L. Bog Huckleberry. 
A characteristic tundra shrub, in which situations it occurs 
sparingly but uniformly distributed. (No. 6.) 
Nephrophyllidium crista-galli (Menz.) Gilg. Deer Cabbage. 
The open, boggy hillsides of the region are clothed with a 
profusion of deer cabbage. Usually it occurs in masses to the 
exclusion of other hillside plants. Above timber-line it is much 
more sparingly distributed. (No. 1.) 
Sambucus racemosa li. Elder. 
Found sparingly distributed in the littoral zone associated 
with Rubus spectabilis, and again above timber-line on steep hill- 
sides with Iibes and Alnus. Nowhere did this species occur in 
clumps, or form any considerable proportion of the flora. (No. 
39.) 
Viburnum pauciflorwm Pyl. High-bush Cranberry. 
The occurrence of this shrub is also very irregular and seat- 
tered. A few were found along the open margins of streams and 
about the edges of the tundra. (No. 54, foliage only.)
