Branches subterete, greyish, fairly slender, about 1 1/4 lin. in diam. 10 in. below the apex, finely lenticellate, young parts pruinose; internodes up to 1 in. long. Leaves alternate, those of the previous year mostly falling off at the time of flowering, elliptic-oblong, rounded at the apex, obtuse or cuneate at the base, 1 3/4–2 1/4 in. long, 2/3–1 1/6 in. broad, coriaceous, glabrous or minutely puberulous, distinctly 3-nerved; nerves raised, especially on the upper surface; petiole about 1/2 lin. long; leaves of the flowering shoots elliptic or elliptic-oblong, 4–7 lin. long. Flowers fascicled on axillary leafy cushion-like short-shoots; pedicels 3/8– 1/2 lin. long; bract cupular with a concave dorsal lobe, glabrous, dorsal margin 3/4 lin. long, conspicuously keeled, keel 3/4 lin. long, 1/4 lin. broad above, narrowed downwards, truncate above or produced into a horn, ventral margin 1/2 lin. long. Receptacle and calyx together tubular, 2 1/2–3 lin. long, glabrous. Calyx 1 3/4–2 1/4 lin. long; lobes short, crenulate. Corolla 1 1/4 in. long or more; tube cylindric, about 4 1/2 lin. long, with 5 slight horizontal depressions outside 2 1/4–3 lin. above the base alternating with the lobes and corresponding to 5 ovate-oblong deflexed densely papillate appendages inside the tube, 3/8 lin. long; lobes about 1 in. long, linear, slightly broadened upwards, reflexed below the middle. Filaments inserted about 1 3/4 lin. above the base of the corolla-lobes, about 6 lin. long, broadened into the base, slightly tapering upwards, involute, with about 5–7 transverse grooves on the dorsal surface, tooth 1/8– 1/6 lin. long; anthers linear, 3 1/2 lin. long. Disc 1/8– 1/6 lin. high. Stigma ellipsoid, 1/4 lin. long.
