Characteristics

A scandent shrub. Branches long, obscurely 4-angled, glabrous, lenticelled. Leaves 14-19 cm long, usually 9-foliolate; petiole about 4 cm long; leaflets ivy-green, dark above somewhat lighter and minutely gland-dotted beneath, ovate, to narrowly ovate, shortly acuminate, acute, oblique at the base, coarsely crenate on the margin, the average size is 3-6 cm long and 2-3 cm broad, twice or less than twice as long as broad, petioled; petiolule 3-10 mm long. Inflorescence a terminal panicle, few-to many-flowered, branches of the panicle opposite and decussate, glabrous, lenticelled; pedicels 0.4-1.5 cm long, bibracteate near the base and articulate near the apex, the upper portion short and thick about 2 mm long forming a stipe to the flower and falling with it. Calyx inflated, subpetaloid, whitish, 5-lobed and 5-angled, glabrous without and minutely glandular within at least in upper half (glands minutely stalked); tube about 1 cm long; lobes triangular oblong, about 8 mm long usually shorter than the tube, 5 mm broad at the base with the apex apiculate and margins minutely ciliate, eventually spreading to reflexed. Corolla a pale lavender-violet, with the tube pale vinaceous lilac within, faintly tinged yellow and striped (the stripes gold in the basal half and in the upper mallow-purple) faintly scented, about 7.5 cm long; tube funnel-shaped, glabrous without, microscopically glandular in the basal portion within, and sparsely pilose on the lower portion of the throat; the lower narrowly cylindric part about 1.7 cm long, usually longer than the calyx tube, the funnel-shaped upper portion gradually widening to the mouth and somewhat compressed; mouth about 3 cm broad and 1 cm deep; limb 2-lipped, lobes ciliate and faintly and widely undulate, pilose at the sinuses, about 2 cm long and 3 cm broad, the upper pair erect and recurved, the 3 lower spreading with the apical portion somewhat recurved. Stamens 4, included, didynamous, with a staminode between the short posticous pair; filaments white, minutely glandular at the base (glands stipitate) and sometimes sparsely pilose; anther cells eventually diverging, connective produced into an incurved apex and with a dorsal crest between the cells. Disc thick, whitish, annular-cupular, about 1.5 mm high and 2.5 mm in diam. Ovary green, cylindric, 6 mm long, 2-celled; style about 3 cm long, tinged with mallow-purple, 2-lobed, lobes oblong, 2.5 mm long. Fruit 30 cm or more long, sub-cylindric, somewhat compressed, about 10 mm broad and 3 mm thick with the septum running like a midrib down the centre of the broad side; apex acute. Seeds closely packed along a flattened free-central placenta, compressed, with a hyaline border which spreads out into a wing.

Inflorescence a terminal panicle. Flowers with the calyx large, cupular-campanulate, 1.5-2 cm long, strongly 5-dentate with apiculate lobes, pale lavender when fresh; corolla pale lavender or pinkish with a magenta patch at the base of the 2 adaxial lobes, the tube white with deep magenta lines inside and some pinkish splotches near the base, cam-panulate above a short cylindric base, 6-8 cm long, with scattered lepidote scales on the lobes, glandular-pubescent at the level of stamen insertion inside and pubescent with kinky trichomes in the sinuses between lobes, otherwise glabrous; stamens didynamous, the thecae divaricate, 3 mm long, the longer filaments 1.9-2.0 cm long, shorter filaments 1.4-1.5 cm long, the staminode 3 mm long, inserted ca. 10 mm from base of corolla tube; pistil 3.2-3.4 cm long, the ovary linear, glabrous, 5 mm long and 1.5 mm wide, the ovules 6-seriate in each locule; disc pulvinate, 0.5 mm long and 1.5-2.0 mm wide. Capsule (Sprague) linear and leathery.
Vigorous, evergreen, glabrous liane. Leaflets (5)-7-9, 2-7 × 1-3 cm (larger on strong vegetative shoots), usually lanceolate-ovate, sometimes ovate to broadly oblong-elliptic, serrate, becoming serrulate towards infl.; base cuneate, rounded, truncate, often asymmetric; apex short-to long-acuminate; petiolule to 1 cm long. Panicle many-flowered; peduncles and pedicels purplish. Calyx 1.2-1.8-(2) cm long, pinkish; teeth 4-7 mm long, triangular; apiculus c. 1 mm long. Corolla 6-8 cm long, pink with rose-red veins, especially inside tube; limb broader than high; lobes 1.2-2 cm long, suborbicular. Filaments with numerous short-stalked yellow glands at base. Style < to slightly > longer stamen pair, 2-3 cm long. Capsule rarely formed, 16-26 cm × 5-10 mm; valves coriaceous. Seed wings nearly 1 cm wide.
Scrambler, occasional shrub; evergreen, branches terete, ribbed, glabrous with few minute scales, nodes pilose. Leaves compound, 7-9 leaflets, ovate, deep green, glabrous, lower surface gland-dotted, margins crenate. Inflorescence many-flowered panicles; rachis and pedicles glabrous. Flowers pink, scented. Calyx campanulate, glandular above, lobes deltoid-ovate, mucronate, ciliolate. Corolla funnel-shaped, 5-lobed, glabrous outside, nearly so inside. Flowering time Nov.-Apr.
