Massive arborescent pachycaul to c. 2.3 m tall; trunk erect to decumbent, to 1.2 m long × 12 cm diam. Leaves several together in a terminal crown; petiole to c. 90 cm long, sheathing in the lower ?-½; wings of sheath tapering, fully attached to the petiole; blade mid-green adaxially, slightly paler abaxially, sagittate, to c. 80 cm long × 50 cm wide; anterior lobe to c. 70 cm long, tip obtuse and apiculate for c. 2 cm; posterior lobes to c. 23 cm long, narrowly rounded; midrib abaxially prominent, often adaxially whitish when fresh; primary lateral veins c. 8 on each side of midrib, distant, alternating with lesser interprimaries and diverging at c. 80°, occasionally branched near base of blade, adaxially impressed (the lamina bullate in between), abaxially prominent when fresh (not so when dry); secondary venation somewhat obscure, arising from the midrib and the primary veins; tertiary venation obscure. Inflorescences 2-several together; peduncle about half the length of the petioles, to c. 45 cm long, apically down-turned so inflorescences nodding, subtended by lanceolate green cataphylls to 30 cm long. Spathe to 36 cm long, lower spathe green, subcylindric, c. 7.5 cm long, differentiated from the limb by a weak constriction; limb white, lanceolate, hardly opening, deciduous, apically acuminate for 5-6 cm. Spadix sessile, narrowly spindle-shaped, to 29 cm long; female zone subcylindric-slightly conic, to 6.5 cm long, c. 2 cm wide at base, obliquely inserted; pistils very numerous and crowded; ovary more or less cylindric, 3 mm long; stigma sessile, button-like, papillate, as wide as ovary, 0.5 mm diam.; interpistillar staminodes irregularly scattered through female zone, clavate, about the height of the pistils, c. 0.4 mm diam. at top; sterile interstice isodiametric with top of female zone, very short in proportion to total spadix length, c. 5 mm long, composed of a mixture of crowded interpistillar staminodes, sterile and incompletely fertile stamens and ?abortive pistils; male zone 9 cm long × 1.7 cm thick, slightly obconic in the lower 2 cm, the rest cylindric; stamens white to yellow, very crowded, more or less dumbbell-shaped, truncate with the connective not or hardly exceeding the thecae, c. 1 × 0.5 mm; appendix white to creamy pink, 12 cm long, basally isodiametric with top of male zone, tapering to a fine point; staminodes of appendix flat-topped, irregularly polygonal, c. 1 mm diam. Fruiting spathe to c. 10 cm long (not seen in ripe fruit), narrowly urceolate.
