Burtt, B.L. (1936) Bulletin of Miscellaneous Information, Kew : 495. Type: Queensland, Slopes of Thornton Peak, March 15, 1932, Brass 2311; holo: ?.
A slender vine not exceeding a stem diameter of 2 cm. Adventitious roots often present.
Leaf blades about 8.5-20 x 2.5-6 cm, petioles about 3-6 cm long, deeply grooved on the upper surface and winged for more than half the length. Intramarginal veins two. Lateral veins numerous and parallel.
Flowering spike about 16-17 mm long, +/- enclosed in a spathe about 12-19 mm long until anthesis. Spike borne on a peduncle about 2 cm long. Individual flowers sessile(?), about 1.7-2 mm long. Tepals six, about 1 mm long, each forming a hood over an anther. Anthers about 0.75 mm long, almost sessile. Ovary about 0.75-1 mm long, ovules one per locule.
Infructescence about 2.5-3 cm long on a stalk about 3-10 cm long. Spathe about 3-3.2 cm long. Individual fruits ellipsoidal, about 15-18 x 10 mm. Seeds about 14-16 mm long. Embryo massive (about the size of the seed) not differentiated into radicle and plumule or not very obviously differentiated. Plumule in a cavity near the apex of the seed.
Usually two or three cataphylls produced before the first true leaf. First true leaves small, about 5-8 mm long, elliptic, apex mucronate or aristate, petioles winged and clasping the stem or petioles absent, and the base of the leaf blade clasping the stem. At the tenth leaf stage: leaf blade elliptic, apex mucronate, base clasping the stem. Venation meagre but usually with five longitudinal veins (including the midrib). Adventitious roots produced at each leaf node. Seed germination time 28 to 65 days.
