1152. B- petrophyllum, R. S. WILLIAMS, Bull, of New York

In low dense tufts or sometimes in thin mats with long creep- 

 ing 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 ad- 

 jacent 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 I mm. broad. Lid conical its height about equal to 

 basal diameter. Annulus of two lows 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
