Stem-leaves with a broad base; costa short, generally vanishing near the middle. Branch-leaves narrow; costa nearly reaching the acumen.

Capsule arcuate; pedicel very rough. Stem subpinnate. Differs from B. velutinum and B. intricatum: Leaves faintly denticulate filiform-pointed; alar cells often dilated. Perichetial leaves nearly entire with a long filiform deflexed point. Capsule oblong-cylindric, arcuate. Tufts loose, sparingly radiculose dusky green. Branches faintly compressed.

1151. B. cirrosum, Schwaegr.

1152. B. petrophyllum, R. S. Williams, Bull, of New York Bot. Gar., Vol. II., p. 136, 1901.
In low dense tufts or sometimes in thin mats with long creeping stems and short subpinnate branches. Stem leaves 1.5 mm. long by .04 mm. wide, narrowly ovate-lanceolate, about one-half costate, serrulate all round, more or less decurrent and margin reflexed near base, not very concave, and scarcely or not plicate. Median leaf-cells linear, flexuous up to .065 mm. long, and .005 mm. wide. Alar cells short and broad, not forming a distinct cluster. Branch leaves very similar to stem leaves but mostly a a little smaller with longer costa ending in spine on back and adjacent cells, sometimes papillose by the projecting upper ends. Inner perichetial leaves pale ecostate, gradually narrowed to a slender, flexuous, serrulate point, with rarely I or 2 coarse teeth at its base. Capsule nodding, curved with lid about 2.5 mm. long and 1 mm. broad. Lid conical its height about equal to basal diameter. Annulus of two rows of cells. Teeth of peristome hyaline bordered, papillose above, outer plates striate, inner lamellae about 30, segments without rounded perforations, more or less split along the keel with mostly 2 appendiculate cilia
19 1/2 between. Seta rough throughout, up to 1 cm. high. Smooth spores up to 011 mm.
On rock at Dawson, Yukon In good fruit, June 24th, 1898. This species is evidently nearest to suberythrorrhizon but differs in the rough pedicel, leaves narrower, less serrate and plicate, and cilia appendiculate. (Williams.)
