A climbing shrub, quite glabrous except the inflorescences; tendrils unknown; young branches brown, dotted with lenticels. Leaves oblong or elliptic-oblong, abruptly acuminate, cuneate at the base, 3–4 in. long, 1 1/4–1 1/2 in. broad, wavy along the margins, coriaceous; midrib flat or convex above, prominent below; secondary nerves 4–5 to an inch (15–20 on each side) with parallel fainter tertiary nerves between them, like the obscure reticulation very faintly raised on both sides; petiole 1/2 in. long. Cymes axillary, many-flowered, slightly exceeding the petioles; flowers distinctly, though shortly, pedicelled, very finely puberulous; bracts minute. Calyx 1/2 lin. long, minutely pubescent; sepals ovate, subacute, ciliolate. Corolla glabrous without; tube subcylindric, 1 1/2 to almost 2 lin. long, widest at the middle, pubescent within; lobes linear-oblong, slightly longer than the tube. Stamens inserted slightly below the middle; anthers ovoid, minute, acute, as long as the filaments or longer, finally nodding. Ovary globose-ovoid, glabrous, imperfectly 1-celled, gradually passing into a very short style; stigma globose-ovoid, apiculate, as long as the style. Ovules 2-seriate (?), 3–4 in each series.
