    Hymenophyllum Tunbridgense is a native of the southern counties of England. I have seen numberless specimens from Kent and Sussex, and I am told by different botanists of its occurrence in Cornwall, Devonshire, Somersetshire, and Glamor- ganshire; but as I have seen no specimen from these counties, and am therefore uncertain as to the species, I have refrained from assigning these habitats to either. In the south and west of Ireland, Tunbridgense appears to be very abundant. I have found it clothing the rocks about Killarney in very great beauty and profusion. The roots are black, wiry, and very slender; the rhizoma long, black, slender, wiry, and creeping. The fronds consist of a branched series of veins, each being clothed with a membranous or filmy wing, as in Trichomanes: the branches or pinne are alternate, and each more or less subdivided ; the subdivisions or pinnule are mostly in pairs: the margin of the wing is crenated, and very minutely spiny: the masses of thecz are in flat marginal receptacles, situated at the union of the pinne with the rachis: in this species these receptacles have a serrated external margin.
