Dipteris wallichii (R. Br.) Moore

Terrestrial fern.Rhizome creeping, 1 cm to 1.5 cm thick, stout, densely scaly; scales narrow, linear, hard, subulate-setaceous, margin shortly tubercled, black. Stipes erect, grooved above, hard, polished and smooth, glabrous. Lamina about 30-50.Scm long and much wider than long, fan-like, bipartite into two equal broad-cuneate portions which are palmately and dichotomously divided; segments oblong, apex acuminate, margin entire; costae prominently raised above and below, from the summit of the stipe dichotomously repeatedly branched veins pass through the frond with 2 main costae run through each segment which are united at the apex; venation prominently raised below, reticulate; all the costae are united by transverse flexuose costules; free veinlets present in the aereoles; texture coriaceous; lamina glossy-green above, coppery-green beneath, glabrous. Sori small, round, copius, superficial, scattered in the aeroles; sporangia oval, short-stalked, light-brown, without paraphyses. Spores oval, hyaline, pale-white, exine smooth[BD14, 1]
