Paroicous ; in small tufts or gregarious, stems 5 — i in. high, simple, 

 pale silky green. Comal leaves elongato-lanc, erecto-patent, acute, 

 more or less sharply serrate at apex, margin recurved below middle, 

 nerve stout, vanishing at or below apex, cells above linear-rhomboid or 

 subvermiform, basal narrow hexagono-rectangular. Caps, on a long 

 purple seta, suberect or inclined, very narrow, elongato-elliptic, with 

 the neck longer than the sporangium, pale cinnamon-brown ; when dry 

 and deoperculated, ascending, slightly constricted below the mouth ; lid 

 orange, acute or slightly rostellate, teeth lanceolate-subulate, yellowish, 

 processes of endostome punctate, entire, cilia two, short or rudimentary. 



Hab. — Rocks and gravelly banks in subalpine places ; not uncommon. Fr. 8. 



An elegant species, readily known by its clavate capsule and the most 

 distinct of these three closely allied plants, although some forms occur with 

 a shorter capsule which approach the other two more nearly. Pohlia longicollis 

 (Swartz) is also allied, and may be found in the north, as it occurs in Norway 

 and Lapland ; it is a more robust plant with larger and broader leaves, the 

 capsule with a shorter, thicker neck, and endostome well-developed. 



Sect. 2. LAMPROPHYLLUM. Leaves broader, more laxly areolate, 

 the comal less suddenly elongate. Caps, thicker, with a short neck, 

 membrane of endostome broader, with cilia.
