Characteristics

Underground parts unknown. Plant glabrous. Stem in the upper parts unarmed, faintly ridged. Bulbils none seen. Leaves alternate, but often two so close as to appear opposed, elliptic or elliptic-ovate, abruptly acuminate, rounded at the base, chartaceous, to 12 × 5½ cm, 7-nerved; upper surface quite smooth; petiole to 2 cm or about ¾ the length of the lamina. Male flowering axes in dense fascicles in the axils of leaves, up to 10 cm long with perhaps 60 flowers spaced 2-3 times their diameter apart; axis slender, angled, slightly flexu-ous. Bracts deltoid-acuminate, 1 mm long. Buds ovoid from a narrow base, to 1 ¼ mm long. Tepals said to be greenish white. Stamens in two series, obviously by elevation of the torus as described in D. sexrimata; the torus raises those before the inner tepals higher than those before the outer tepals. Female flowering axes attaining 60 cm in length with upwards of 100 flowers; axis slightly angled. Capsules unknown.
