Leaves 5-10(-13), developing after the flowers, glaucous, broadly linear to oblong-lanceolate or lorate, 30-80 cm long, 1-2-3 cm diameter, broadest at middle or slightly above, erect, straight to arched or often twisted near the apex, abruptly narrowed above into obtuse to subacute apex, glabrous near the base; base truncate, with long membranous sheath. Aerial scape solitary, solid, compressed, glaucous, 17-24 cm long, dilated at the tip (1.0-3.0 cm diameter), glabrous. Spathe 2-valved, unequal, imbricate, lanceolate or ovate lanceolate, (5-) 6-9 cm long, 2-3 cm diameter, gradually or abrubtly tapering above into a long acuminate apex. Flowers 5-14, medium-sized, 13-18 cm long, 1.5-2 times as long as the spathe, fragrant, pedicelled; pedicel stout, 1-2 cm long, commonly shorter than the ovary or rarely equal, perianth white, 11-16 cm long; perianth-tube (7-)8-12 cm long, 1.5-2 times as long as the perianth-segments; perianth-segments white, with a broad green mid-stripe outside (4-6 mm diameter), patent, 5-7 cm long, 5-10 mm diameter; outer narrowly spathulate to lanceolate-oblong or linear-oblong, obtuse to subacute at the mucronate or shortly cuspidate apex; inner slightly shorter and narrower, lanceolate or oblong-lanceolate, acute or subacute, Capsule oblong-ovoid or broadly ellipsoid to broadly cylindrical, (2.5-)3-4 (-5) cm long, (2-)2.5-3.5 cm diameter, commonly with a peg-like projection; seeds irregularly angular and compressed or cone-shaped, 10-14 mm long, 8-10 mm diameter; testa black, sublustrous
