This plant agrees closely with Schwaegrichen's figure and descrip- 

 tion above-cited, with the sole exception that the stems are rather 

 more elongated. Through the favour of Mr. Wilson I have examined 

 specimens gathered in the Canary Islands by Mr. Webb, and named 

 " Br. platyloma, Schwgr." by Dr. Montagne : these agree in all cha- 

 racters of importance v.'ith the Pierrefitte plant. The latter differs 

 essentially from the B. platyloma of B. and S. (i?. Donnianum, Grev.) 

 in the leaves having a broad margin of 4-6 rows of cellules (" in sex 

 circiter series digestse," Schwgr. /. c), but composed of otily a single 

 layer ; while those of B. Donnianum have a margin only 2 or 3 cellules 

 in width, but decidedly thickened (" margine e strato diiplici cellula- 

 rum .... circumducta," Br. Europ.). in other words they are jortc^- 

 lomatous but not platylomatous. The leaves of the true B. platyloma 

 differ further in being far smaller, rigid, nearly erect, by no means 

 " in comam patulam congesta " (as represented in ' Bryol. Europsea,' 

 but not in Schwaegrichen), the strong nerve running out into a point
