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 with the Pierrefitte plant. ‘The latter differs 
essentially from the B. platyloma of B. and 8. (B. Donnianum, Grev.) 
in the leaves having a broad margin of 4-6 rows of cellules (‘‘ in sex 
circiter series digestz,’’ Schwer. J. c.), but composed of only a single 
layer ; while those of B. Donnianum have a margin only 2 or 3 cellules 
in width, but decidedly thickened (‘‘ margine e strato duplici cellula- 
rum... . circumducta,” Br. Europ.), in other words they are pachy- 
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. Europea,’ 
but not in Schwaegrichen), the strong nerve running out into a point
