PELLAEA SMITHIT C. Christensen, Acta Hort. Gothob. 1: 84 t. 18 (1924); Ind. Fil. 
Suppl. IIT 135 (1934). 
Rhizome short, erect, densely scaly at the apex and the base of stipe; scales 
small, linear, rigid, brown, shining, the outer ones are often shining black; fronds 
numerous, Caespitose, stipe 6-10 em long, firm, rounded, sparcely scaly through- 
out, brownish-straminous, lamina ovate-oblong or deltoid, 4-6 cm long, 4 cm 
broad, coriaceous, bipinnate, rachis glandular, grooved above; lateral pinne 8- 
4-jugate under the pinnatifid deltoid apical part similar to the lateral ones, sessile, 
opposite or subopposite, deltoid, to 2 em long and broad, the basal pair hardly 
larger than those above, pinnatifid to the costa into 3-5 pairs of linear entire, 
acute segments 1-1.5 cm long, 1-1.2 mm broad, the lower ones adnate, the upper 
ones decurrent, costa and costules deeply sulcate above, prominently raised under- 
neath; veins in segments hidden, biforked, veinlets oblique; sori intra-marginal, 
distinct, terminating each veinlet, indusium linear, continuous. till very apex, 
covering the entire under surface, gray at first, brown at last, persistent, with 
glandular-ciliate margin; spores small, minutely verrucose.

This peculiarly distinct little fern is closely related to P. nitidula (Wall.) 
Baker from Northern India and South-western China, differs in still simpler pin- 
nation, much lighter-colored stipe and rachis, which are only sparcely glandular, 
and in much broader indusium. As first observed by its author, all the speci- 
mens cited above are found to be fertile in every segment.
