Steenis, C.G.G.J. van (1957) Nova Guinea Series 2 8: 174.
Jungle Vine; Vine, Jungle; Jungle
Vine stem diameters to more than 7 cm recorded. Living bark layer quite thick, e.g. 15 mm. Blaze marked by white granular stripes and white fibrous stripes. Lenticels often large and conspicuous.
Leaflet blades about 8.5-17 x 4-6.5 cm, leaflet stalks about 0.5-3.5 cm long. Middle leaflet larger than the lateral leaflets. Stalk of the middle leaflet longer than those of the lateral leaflets. Compound leaf petiole about 3-10.5 cm long. Lateral leaflet blades oblique at the base. Lateral veins about 8-10 on each side of the midrib, forming loops inside the blade margin.
Flowers about 12-15 mm diam. at anthesis. Calyx tube about 5-7 mm long, lobes about 1-2 mm long. Corolla 2-lipped, corolla tube curved, about 30 mm long, lobes about 3-5 mm long. Stamens attached to the corolla tube about 5 mm from the base. Staminal filaments about 25-30 mm long, densely pubescent near the base, glabrous elsewhere. Filaments attached to the back of the anthers near the apex, connective absent and anther sacs almost free from one another. Disk green, about 3 mm high, lobed at the apex and surrounding the ovary. Style about 30 mm long, stigmas 2, flat.
Cotyledons +/- reniform, wider than long, about 13-16 x 18-22 mm, apex deeply emarginate, base cordate. First pair of leaves elliptic, glabrous (except for the midrib on the upper surface), apex bluntly pointed, base attenuate. At the tenth leaf stage: seedling completely glabrous, leaf blade elliptic to obovate-oblanceolate, apex acuminate, base attenuate, gradually merging into the petiole. Midrib raised or flush with the upper surface. Lateral veins forming loops inside the blade margin. Numerous crater-like glands visible on the underside of the leaf blade. Small stipule-like glands present on the stem between the petiole bases. Seed germination time 15 to 21 days.
This species could have some horticultural value as it can produce quite decorative bunches of pink to reddish flowers.
