Leaf blade pedate, reaching 9 segments, glaucous underneath; segments elliptic, acuminate, sessile, 0.5-1 cm wide at the base, each slightly divergent from the others, shortly decurrent on the rachis; the middle segment is the biggest, ca. 16 x 5-6 cm; 9-12 primary lateral veins on each side; the size of the other segments decreases towards the outside; primary lateral veins of segments inserted at an angle of 50-60º with the medial rib and joining together in a collective vein, 3 mm from the edge of the leaf. INFLORESCENCE: Peduncle 28 x 0.25-0.4 cm. Spathe ca. 4 times longer that the spadix, rolled at the base into a tube, ca. 3cm long, 0.7-1 cm diameter; spathe decurrent, attenuating at the apex and tapered to a filiform point, , very elongated, 11-12 cm long, recurved towards the base.
