Rhizome epigzeous, wiry, branched, wide-creeping, densely clothed in rufo-brown, 
hair-like, unicellular, softly shaggy hairs; fronds far apart, erect, stipe I.5-5 cm long, 
slender, straminous, densely clothed throughout in similar hairs, lamina oblong or oblong- 
ovate, acute or bluntish, base not narrowed. 1.5-6 cm long, 1-2 cm broad, bipinnate; pinnae 4- 
7-jugate under pinnatifid apex, petiolate, 5-7 mm long, deltoid, obtuse, base cuneate, pinnate 
with I-2 pairs of oblong-ligulate entire or slightly notched uninerved decurrent segments 
under the trilobed terminal part; texture thin herbaceous, rachis, petiole and both sides 
copiously clothed in reddish-brown, spreading, septate, transparent hairs; veims visible 
against light, one to each lobe, falling far short below apex; sori linear, along veins and 
costa of pinnae, exindusiate; sporangium broadly subglobular, shortly stalked; spores 
ovate-reniform, discolored, bilateral, and smooth (with both perispore and exospore).

This is a singularly interesting little fern, epiphytic on tree trunks or growing in 
mosses on rocks under forest. The genus comprising only one species, differs from 
Anogramma in wide-creeping and branched rhizome, with distant leaves, dense reddish- 
brown articulated hairs in all parts and the bilateral reniform-ovate spores.
