the Northwest. 
Mosses. 
Polytrichum juniperinum Willd. Near Mt. Hood P. O. ; very abund- 
ant; on soil in dry open woods. The most abundant of our Polytrichaceae 
in the Coast region of the Northwest. 
Polytrichadelphus LYALLii Mitt. On soil in wood ; on slope of Mt. Hood, 
alt. 3000-4000 feet. This is not a rare form in high altitudes in the North- 
west. It was here growing with Rhodobryum lucidum. 
Rhodobryum lucidum (E. G. B.) Frye new comb. Mt. Hood; alt. 3000- 
4000 feet; in fir and hemlock woods, on dry ground, along Cloud Cap 
Inn trail. This splendid moss, with large, Mnium-like leaves, and very 
large capsule, was abundant here, and was not seen at any other place. 
Mnium punctatum Hedw. Mt. Hood P. O. ; along stream on wet soil in 
damp woods. Common. The leaves were larger here than usual, and thus 
attracted the attention. 
Hylocomium robustum (Hook.) Kindb. Mt. Hood; in woods along with 
Rhodobryum lucidum ; alt. 3000-4000 feet ; on soil in fir and hemlock 
woods. This form is found usually in mountains in the Northwest at an 
altitude of 1500-5000 feet. Usually Camptothecium megaptilum is associ- 
ated with it, but that was not found on Mt Hood. 
Rhacomitrium lanuginosum Brid. Near Mt. Hood P. O. is an old lava 
flow, perhaps 150 feet high, a quarter of a mile wide, and 5 miles long, com- 
posed of sharp edged fragments of one-half to three feet in diameter. This 
moss is abundant on these rocks in places, and forms practically the only 
vegetation at the lower end of the flow. Alt. about 2000 feet. 
Grimmia donniana Smith. On rocks; Mt. Hood; alt. 9000 feet. This is 
the last plant noticed in the ascent, other than lichens and Sphaerella 
nivalis “ Red Snow.” University of Washington.
