Characteristics

Scandent or creeping shrub, climbing branches rooting at nodes. Stem ridged, pubescent with recurved hairs. Petiole 0.5-1 cm long, pubescent, vaginate to apex; blade not conspicuously glandular-dotted, elliptic, subobovate or ovate, 4-17 x 3-6.5 cm, (on young creeping branches ca. 1.5-5 x 0.8-1.8 cm), margin occasionally ciliate, apex (long-)acuminate, base unequally attached to petiole difference 0.1-0.7 cm, unequally cordate or obtuse, glabrescent but veins may be recurved-pubescent; pinnately veined, secondary veins 6-8 per side, originating from throughout primary vein, impressed above, prominent below, tertiary veins inconspicuously reticulate. Inflorescence horizontally oriented? later recurved; peduncle 0.8-2 cm long, pubescent or glabrescent; spike protandrous (presenting staminate flowers first, pistillate flowers afterwards), 1-3.5 cm long, green, not apiculate; floral bracts pubescent at base, densely marginally fringed; stamen 1 per flower, far exserted, recurved, 2-3 mm long.
