86 Muhlenbergia, Voluine 9 
ABIES GRANDIS Lindl. 
A common forest tree near the coast, 4792, August 25, I9II. 
PSEUDOTSUGA TAXIFOLIA (Lamb.) Britton 
The most abundant and commercially important timber tree 
of the region; 4742, August, 1911. 
PICEA SITCHENSIS (Bong.) Traut. & Meyer 
The Sitka spruce, or tideland spruce, occurs in greatest 
abundance within the fog belt near the ocean but some of the 
largest individual specimens are found scattered through the 
forests of Douglas fir and hemlock in the foothills and moun- 
tains; ¢7¢¢, August, IgIt. 
Two other conifers, which are common in this region, 7huja 
plicata Donn, and 7suga heterophylla (Raf.) Sargent, were not 
collected. Dr. W. Hayden showed me a cone of Pznus ponde- 
rosa Dougl., which he said came from a tree near Myrtle Point, 
within fifteen miles of Marshfield. Unfortunately, I was unable 
to verify this unusual record, but have no doubt as to its authen- 
ticity, as Doctor Hayden is a botanist of no mean ability.
