 more solid leaves distinguish this from nearly allied species. 

 It has the habit of B. capillare.

 short innovations ; upper leaves crowded into whorls, erecto- 

 patent, undulated when dry, ovato-oblong, concave, serrulate,

Distinguished, according to Schimper, from B. capillare 

 by the form of the leaves, the margin sharply toothed above, 

 revolute below, and narrowly bordered, their firmer consistence, 

 and brilliancy, their imbrication when dry, and their smaller 

 shorter sporangium. 



22. B. pseudotriquetrum, Schwag. ; dioicous, csespitose ; 

 stem erect, slightly branched, radiculose ; leaves erecto-patent, 

 subdecurrent, ovato-lanceolate, concave, slightly bordered ; 

 margin recurved, entire or slightly toothed at the apex ; 

 nerve reaching to or slightly beyond the tip ; leaf- cells rather 

 narrow ; sporangium ovali-pyriform, oblong or subcylindrical, 

 pendulous ; lid mammillary. Hook, fy Wils. t. xxx. ; Eng. Bot.
