Hab. In Ireland and Scotland, common on wet rocks : in the alpine parts of England, in 
similar situations, it is also not rare. 
Plant covering rocks, sometimes to a considerable extent, with pale, glaucous-green patches. 
Fronds an inch, or an inch and a half in length, horizontally creeping and imbricating each 
other very closely. Their width is scarcely more than half a line. They are branched in 
a dichotomous manner twice or thrice ; the apices always obtuse, the edges waved, but 
entire; the center furnished with a strong nerve or rib; and the whole superficies, both 
above and below, and at the margin, covered with numerous short, white, pellucid, 
simple, jointless hairs, which give the plant a pubescent appearance. I he texture is 
delicate, the cellules small and roundish, but indistinct on account of the pubescence. 
The color is a pale green, rendered still paler by the white hairs. 
Male Fructification most abundant on the under side of the plant, and always attached to the 
mid rib. The 
Anthers are two or three in number, inclosed in a young “ innovatio frondis, , spherical, of 
a pale brownish green color, terminating a short white footstalk. 1 he innovations, on 
the decay of the anthers, appear to shoot out into perfect fronds, which, probably, are 
detached from the parent plant, and become new ones. 
No Female Fructification has been discovered in this, nor, as far as I can learn, in any 
other country.
