616. **Grimmia Agassizii** (Sull. et Lesq.) Lesq. et J. 1884. Schistidium angustum Hag., 1890. Schistidium lineare (Chal.) Limpr. (1904). Grissomia angusta (Hag.) Par. Index bryol. (1904). Schistidium lineare (Chal.) Limpr. Laubm. III, p. 710 (1904).

Tonquin Valley, Jasper Park, B. C., Can.

Note. The plants outside of the little pocket are from Norway, coll. Hagen, 3-8, 1894.

The description in Lesq. et James, Manual p. 136, "leaves . . . coarsely sparingly dentate at the apex" is true only rarely on co-type material distributed in Sull. et Lesq. Musc. Bor.—Am. Exsicc. n. 137. On most of the plants all the leaves are entire, as in the B. C. and European plants; nor does co-type material prove the teeth "pale—above."

Coll. Mrs. Fay A. MacFadden.
