Climbers. Branches elongated, striate, internodes 7.5-10 mm. Leaves leathery; petiole 7.5-10 × ca. 1 cm, base angustate, apex truncate; leaf blade triangular-lanceolate, much smaller and shorter than petiole, 2.5-4 × ca. 7.5 mm. Inflorescences several to many, borne in a terminal branching system, proximal inflorescences axillary to a foliage leaf, distal ones either subtended by a cataphyll or without a subtending leaf, peduncular axis slender, consisting of 1 to several internodes, sometimes subtended by a prophyll, sometimes also bearing a cataphyll ± halfway up.
Spathe occurrence irregular, often absent, widely spreading, linear-lanceolate or broadly ovate, 5-7.5 mm, margins usually revolute, apex acute. Spadix apparently often functionally unisexual, cylindric, 1.5-2.5 cm, sessile to long stipitate when subtended by spathe. Flowers apparently usually unisexual, sometimes bisexual, congested, with a perigone of 6 free tepals; male flowers with well-developed anthers and apparently sterile ovary, stamens 3-6, free, number often varying on a single spadix; female flowers with large fertile ovary and lacking stamens.
