Sterile frond of young plant trifoliate, apical lamina with cuneate base, the pinnae close to it; lamina of type 38 cm long, consisting of a rather shallowly trilobed apex with strongly cordate base and 1 pair of pinnae 10 cm below it; pinnae about 18 cm long (tips broken), shallowly bi-lobed with a very asymmetric base and stalks 5-7 mm long, strongly cordate on the basiscopic side, narrower and rounded on the acroscopic side, 8.5 cm wide above the basiscopic lobe; main veins widely spaced, upcurved, other veins slender, distinct on the lower surface but not prominent, areoles many with forked included veinlets; lower surface glabrous apart from sparse minute hairs on costae.
