Sterile fronds perennial, coriaceous, deep-green on the upper, pale on the under surface, narrowly lanceolate, subacute at the apex, gra- dually narrowed and decurrent at the base, entire or slig^htly sinuate, with the margin recurved and diaphanous, 15-28 cm. long", cm. broad; veins rather obscure, diverging from the thick costa at an angle of 60-70 degrees, about 2 mm. apart at the base, forked or simple, subparallel, terminating below the mar- gin of the frond in a thickened and simple or forked apex.
