Leaves 16-18; sheath 100 cm long, 63 cm wide at base, with thick brown indument, 40 cm at apex appearing like a petiole; petiole 30 cm long, 10 cm wide at apex, green, adaxially flattened, slightly raised centrally, with acute margins; rachis 330 cm long, green adaxially flattened for 83 cm, thereafter acute, abaxially convex with a whitish indument; pinnae 147-149 on each side, irregularly arranged in groups of 1-6, most commonly of 4-5, the groups very close to each other, basal and apical pinnae almost regularly arranged, on each group the pinnae arranged in different planes, the proximal one of each group slightly ascending, the distal one descencding, the apical 1/2 of each pinnae pendulous, toward the leaf apex the rachis rotates axially, and therefore pinnae appear vertical, all pinnae whitish-silvery below.
