Description
"High climbing or trailing vines, twining upward from left to right. Leaves evergreen, opposite, lanceolate to elliptic, 3-7 cm long, 1-2.5 cm wide, acute to acuminate, entire, base rounded to cuneate; petioles 2-7 mm long. Flowers actinomorphic, heterostylic, axillary, solitary or in cymes; pedicels short, bracteate. Sepals 5, separate to base, lanceolate,, 3-5 mm long, 1-2 mm wide; corolla 5-lobed, yellow, 2-3.8 cm long, the tube gradually flaring upward, lobes 7-10 mm long, spreading; stamens 5, attached to lower part of corolla tube, anthers sagittate; pistil 1, slender styled, 2-cleft, each divided again and appearing 4-cleft. Capsule compressed; seeds many, dull brown, the body roughly papillose." [1]
"Leaf base cuneate to rounded. Flowers very fragrant, usually solitary, rarely in 2-3 flowered cymes. Speals obtuse to subacute. Capsule oblong, 1.4-2 cm long, 0.8-1.2 cm broad, abruptly rounded to a beaked apex; seeds 0.7-1 cm long, membranously winged apically."[1]
