210 BRYACEiE. [Philonotis. 



larged base, acute, the costa projecting on the upper face: cap- 

 sule on a very long subflexuous pedicel, oval-globose or exactly 

 spherical, oblong, curved and closely furrowed when dry ; teeth 

 shorter, more distantly articulate, and the cilia nearly half as 

 long as the segments. — Coroll. 86. J3artramia calcarea, Bruch 

 & Schimp. Bryol. Eur. t. 325 ; Muell. Syn. i. 475. 



Hab. Calcareous springs, hills and mountains; rare. White Moun- 

 tains (Oakes) ; Humboldt Mountains, Nevada, and in the Uintas ( Wataon). 



The habitat of this species in North America is still uncertain. The 

 specimens that were determined and distributed nnder this name in Sulliv. 

 & Lesq. Muse. Bor.-Amer. Exsicc. (ed. 2), n. 250, have been considered, 

 by Schimper as a marked variety of P. fontana, or as an intermediate 

 form. 



5. P. Mohriana. Dioecious : the stems short and stout, 

 densely foliate, radiculose below ; branches thick, unequal, gen- 

 erally short, strict : stem-leaves also very strict, open in a dry 

 or humid state, dirty yellow, broadly and exactly lanceolate, 

 long-acuminate, indistinctly j^licate lengthwise, irregularly con- 

 cave at base ; borders narrowly revolute, densely serrulate- 

 denticulate at the apex, nodulose in the lower part by project- 

 ing papillae ; costa deeply canaliculate, excurrent into an awn- 

 like point ; cells of the areolation long, narrow, linear-punctate, 

 papillose ; perichretial leaves similar, broader at base, loosely 

 reticulate : capsule on a flexuous stout red pedicel as long as 

 the stem, slightly oblique, larger, globose, plicate ; lid minute, 

 iimbonate; peristome double, normal. — Dartramia Mohriana^ 

 Muell., Regensb. Flora, Ivi. 482 (1873). 



Hab. Decayed trunks in deep woods; Louisiana {Mohr). 



Differing from P. fontana and P. calcarea in its short stature, and the 

 leaves very strict, lanceolate, loosely retictdate and very papillose. Dr. 

 Mohr remarks in a letter that the species is very near P. Scldumbergeri, 

 a Mexican species, and that he is in doubt of its being North American, 

 having failed to find it again in Louisiana. 



Tribe XII. MEESIE^. 



Plants varying in size, simple or branching by innovations, 

 radiculose-tomentose. Leaves 3-8-ranked, lanceolate or linear- 

 oblong. Calyptra fugacious. Capsule long-pedicellate and 

 long-necked. Lid small, convex or conical. Peristome double ; 

 teeth of the outer much shorter than the carinate-plicate inner 

 membrane (absent in Catoscopium), which is divided into 16
