Characteristics

Stem c. 450 mm tall, 1 mm diam., either simple or forking once, glabrous except for a narrow band of small curved hairs, sparsely leafy. Leaves opposite and decussate, lamina 30-40 x 1 mm, but appearing to be only half the width because of the sharply revolute margins, apex acute, callous-tipped, base sessile, both surfaces glabrous except for a few marginal hairs on young leaves. Flowers 4-5 at each node, pendent. Pedicels 5-7 mm long, pubescent on one side. Calyx segments 2 x 1 mm, lanceolate, sparsely pubescent outside, glabrous inside. Corolla lobed nearly to the base, lobes 9 x 2 mm, oblong, flat, apex obtuse, dorsal surface very sparsely hairy, ventral surface villous, the hairs up to 1 mm long. Corona composed of 5 main lobes alternating with 5 minute ones; main lobes 3-5 x 1.25 mm, much overtopping the gynostegium, lanceolate, thin-textured, almost papery when dry and then red-brown, without an appendage but with 2 narrow fleshy keels running up the inner face; subsidiary lobes c. 0.3 mm long, suborbicular. Anther appendage c. 0.4 mm long, erect, just reaching the rim of the gynostegium; corpusculum c. 0-3 mm long, pollinium attachment subterminal; pollinium c. 0.6 mm long, narrowly pear-shaped, much flattened. Gynostegium 1.5 mm tall, the head c. 0.8 mm in diam., 5-lobed, truncate. Fruit unknown.
