Gibbes, W. H. H. Anastasia Island, Dr. Durhe. (v. V. ) Frond originating in a simple, lanceolate leaf, which, in the American specimens is seldom more than three or four inches long and a quarter inch wide. This leaf is delicately membranaceous, and has a percurrent, slender, inarticulate midrib formed of numerous, closely packed cylindrical cellules. As the plant developes, the midrib throws out at both surfaces numerous similar leaves which in turn bear others ; and thus by the repeated produ...ction of new series of leaves from the midrib of the older, the plant at length becomes a leafy ball, very dense with crowded foliage. The margin is entire and generally flat. The membrane is composed of polygonal cells of which those next the midrib are nearly equal-sided hexagons, those next them oblong, and those toward the margin gradually smaller and more cylindrical. Conceptacles globose, on the midrib. Tetraspores in oblong or linear sori, disposed in pairs at opposite sides of the midrib in the smaller leaves.
