Leaves 6; leaf sheaths 7-15 cm long, densely covered with flat, black scales, extended above the petioles into 9-17 cm long auricles; petioles 16-47 cm long, scaly as the sheaths, the proximal ca. half with closely to widely spaced, recurved, black spines 0.2-0.6 cm long, these sometimes bifid; blades 20 cm wide, split into 10-14 segments, with numerous, minute reddishbrown scales abaxially, with straight sides; costas 0.5-1.5 cm long; middle segment split almost to the base of the blade (to apex of costa) into 2 lobes, these not wider than the other segments, 13-23 cm long, 2.5-3 cm wide at the apices; indentations leading to adaxial folds 1-1.5 cm deep, those leading to abaxial folds 0.4-0.6 cm deep, indentations deeper on lateral segments.
