Gametophyte in glossy, whitish-green to golden-green tufts; stems creeping, irregularly branching ; branches very stout and turgid, julaceous, pointed, sometimes ending in flagellae, 1-3 cni. long; leaves loosely appressed imbricate, somewhat decurrent, lanceolate to broadly ovate-lanceolate, X mm., entire, gradually narrowed to a long filiform acumination, stongly plicate, costate to middle; margins reflexed below; median leaf- cells 12-15:1 ; basal broader and shorter; alar rhomboid-quadrate ; stem and branch leaves little different: monoicous ; perigonial leaves entire, sharply acuminate, ecostate; antheridia short-stipi- tate : perichaetial leaves sheathing, long-acuminate, entire, ecos- tate. Sporophyte 1-2 cm. high; seta red-brown, smooth, twisted to the right below to the left above; capsule mm. long, 3:1, sub-horizontal, curved, somewhat contracted under the mouth when dry ; operculum conic ; annulus of one row of cells; cilia one or two, nodose ; spores 18-24/i, nearly smooth, matur- ing in autumn. ' Type locality European. In alpine or boreal regions in grassy or stony places. Battle Harbor, Labrador (Waghorne); Stephen, Rocky Mts. (Macoun); Greenland (Fl. Gr.). This species has much the appearance of B. glareosuvi but differs in its more turgid branches, entire 'eaves and in being monoicous. Not yet found fruiting in America. The description of the sporophyte is adapted from Limpricht. 10. Brachythecium rutabulum (L.) Br. & Sch. Brj'ol. Eur. fasc, 52-54, pi. S43 ^"d 544- 1853. Hypnum rutabulum L. Sp. PI. 1124. 1753. H
