Descr. Frond spreading over the surface of the rock in broad, indeterminate 
patches, of one, two or more feet in diameter, resembling “ fragments of 
beautiful green velvet’, composed of an under layer of entangled and inter- 
woven, cylindrical filaments producing on the upper surface lineari-clavate, 
vertical branches, of equal length, parallelly arranged into the even velvetty 
surface of the frond, and being, as it were, the pile of the velvet. Substance 
soft and gelatinous, closely adhering to paper. Co/our a brilliant green, 
when wet. 
I am indebted to Mr. Peach of Fowey for livmg specimens of 
this curious plant, which he finds im great perfection at Gorran 
Haven. It appears to be of slow growth; for Mr. Ralfs mforms 
me, that patches cut out one year, are but partially filled up after 
twelve months. I am not quite certain that the Mauritius speci- 
mens, formerly described by me, are identical with the European.
