Fertile fronds (including the elongate fertile pinnae) 9-30 cm. long ; stipe 5-13 cm. long, stoutish, sulcate, dark-stramineous, sparsely villous, glabrate; sterile lamina oblong, obtuse, 4-7 cm. long, 1.5-2.8 cm. broad, once-pinnate, the rachis similar to the stipe; pinnae 6-12 pairs, contiguous or apart, spreading, sessile, the middle onestrapezoid-oblong, obtuse, narrowly rounded -cuneate below, rounded-truncate above and contiguous to the rachis, the lower ones similar but a little shorter, inequilateral, exciso-cuneate below, the terminal pinna as large as those next below (or larger), cuneate, the outer portion rotund or sharply truncate ; leaf-tissue coriaceous, lustrous above, opaque and paler below, more or less pilose, sparsely glandular below; margins thickened, repand, subentire or undulate ; fertile pinnae elongate, 12-20 cm. long, far exceeding the sterile lamina, the stalks slender or stoutish, 3-4 times as long as the panicle, the panicle dense, the lower segments usually remote; spores broadly striate, not echinulate. Sterile fronds with stoutish stipes, spreading; lamina oblong, 3,5-7 cm. long, 1.5-3 cm. broad; pinnae 5-13 pairs, spreading, similar to those of the sterile lamina of the fertile frond.
