Musci Acrocarpi Boreali-Americani

DISTRIBUTED BY JOHN M. HOLZINGER.

225. Polytrichum gracile (Dicks.) Menz.

MR. FOSTER'S NOTE:—The plants appear to have grown under the snow, which apparently had not been melted more than a month. The setae were thus twisted when found. The robust, sterile plant grew beside a log, protected from sliding snow. Ravines very steep and abrupt, and quite dry now, July 27. The humus was smooth and hard—solid, made so by snow.

On humus in ravines along the timber line, alt. 7,000 ft., near Cloud Cap Inn, Mt. Hood, Ore,
