On rocks and sandy banks. Lancashire, Sussex, and 

 Wales. Bearing fruit in early summer. 



The thickened border, consisting of two layers of cells, and 

 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, 

 recurved below, toothed above ; nerve more or less excurrent ; 

 sporangium obconico-pyriform, pendulous; lid conico-apiculate.

On old ant-hills, Sussex, Mr. Mitten. Bearing fruit in 

 summer. 



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, Schw&g. ; 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. 

 t. 2554. ; (Mouff. $ Nest. n. 223.)
