SUMMARY
Slender, leptocaul, homeophyllous liane to 4 m; seedling and pre-adult plants not observed; LEAVES: adult shoot architecture not full observed but seemingly comprised of elongated, clinging, physiognomically unbranched, leafy, non-flowering stems and slightly lengthened mostly unbranched, free, leafy, flowering stems; stems smooth, flexuous, climbing stems ± terete, occasionally weakly angled, free stems terete, to similarly sulcate, without prophyll, cataphyll and petiolar sheath fibre, internodes 0.3-5 x 0.2-0.3 cm on free shoots, flowering shoots with shorter internodes, separated by weak straight leaf scars, older stems woody; flagellate foraging stems not observed; clasping roots and feeding roots not observed; leaves spiro-distichous, slightly scattered; cataphylls and prophylls membranous, caducous; petiole grooved adaxially, 1.5-5 x 0.1-0.18 cm, smooth, with a slight apical and basal geniculum; petiolar sheath slightly prominent, extending beyond the apical geniculum by two ligules, caducous leaving a continuous scar from the petiole base, around the top of the apical geniculum and back to the base; lamina entire, elliptic to elliptic-lanceolate or oblanceolate, slightly falcate, 5-16 x 2.2-7 cm, thinly coriaceous, base cuneate subovate or minutely cordate, apex acute to briefly acuminate, with a small tubule; midrib raised abaxially, sunken adaxially; primary venation pinnate, slightly raised on both surfaces in dried material; interprimaries reticulate to sub-parallel to, but much less distinctive than, primaries, degrading into weakly reticulate venation, very slightly raised abaxially; secondary and tertiary venation reticulate; INFLORESCENCE solitary, subtended by a fully developed foliage leaf and a caducous cataphyll; peduncle slightly compressed-terete, 1-3 x 0.2-0.3 cm; spathe cigar-shaped, apex beaked, 1-4.5 x 0.7-1.2 cm, fleshy, yellow-green to yellow-cream, caducous leaving a large scar; spadix cylindrical, sessile, inserted level on peduncle, 1.5-2.5 x 0.5-0.8 cm, obtuse, white; stylar region rounded-rhombohexagonal, 0.9-1 x 0.85-1.1 mm, truncate; stigma punctiform, c. 0.3 mm diam., slightly prominent in dried material; anthers not exserted at male anthesis; INFRUCTESCENCE not observed.
