stem twining, or occasionally not more than 2–4 in. high and then erect, slender, glabrous; leaves somewhat fleshy, glabrous or with a few scattered short hairs on both sides and with or without a short ciliation; petiole 1–2 lin. long; blade 1/2–1 in. long and 1/4– 1/2 in. broad when ovate, 1–1 1/2 in. long and 1 1/2–3 lin. broad when linear or linear-oblong, obtuse and apiculate or acute; peduncles 1–3-flowered, 1/8– 3/4 in. long, glabrous; pedicels 1–2 1/2 lin. long, glabrous; sepals 3/4–1 1/2 lin. long, subulate, glabrous; corolla-tube 1/2– 2/3 in. long, curved, globosely inflated and 1 1/4–1 1/2 lin. in diam. at the base, contracted to 2/3 lin. in diam. above and dilated to 2 1/2–3 lin. in diam. at the funnel-shaped mouth, glabrous outside, thinly pilose with long fine hairs within, apparently dark purple at the base, but perhaps only inside, whitish above; lobes very slender and claw-like at the erect basal half, inflexed, dilated and all united above into an umbrella-like canopy 1/3 in. in diam., raised 2 1/2–3 lin. above the mouth of the tube, with 10 rounded marginal lobes, which, together with the claws, are shortly ciliate, but the hairs are easily detached, apparently dark purple or green; outer corona 1/2 lin. long, equalling the staminal column, cup-like, apparently 5-angled, truncate or rising into very short deltoid lobes at the angles, glabrous; inner corona-lobes 1/2 lin. long, erect, much overtopping the staminal column, laterally much flattened and about 1/4 lin. broad, broadly recurved-falcate, obtuse, dorsally connected at the base to the outer corona and seeming to form part of it, apparently scarcely incumbent on the backs of the anthers, glabrous. null
