Branches nodose, wrinkled in a dried state, brown or grey, densely lenticellate, 1 1/2 lin. in diam. 8 in. below the apex; branchlets smooth, glabrous, brown, slightly compressed; internodes 1/3–1 1/2 in. long. Leaves opposite, ovate to lanceolate, gradually narrowed to an obtuse or subacute apex, unequal and rounded at the base, more rarely obtuse or subcordate, 2–4 1/2 in. long, 1/2–1 3/4 in. broad, thinly coriaceous, glabrous; lateral nerves about 3 on each side, very oblique, raised on both surfaces, the uppermost running subparallel to the midrib; petiole 3–9 1/2 lin. long. Umbels axillary, fascicled, 4-flowered; peduncle 1–1 1/2 lin. long; pedicels about 1 lin. long; bract obliquely cupular, dorsal margin 3/4 lin. long, ventral margin 3/8 lin. long. Receptacle and calyx together campanulate, 1 1/2 lin. long. Calyx subtruncate, 5/8– 3/4 lin. long. Corolla over 1 3/4 in. long, glabrous outside, apical swelling in bud rounded, basal swelling ellipsoid, 2 1/4 lin. long; tube at first entire on the expansion of the corolla, broadest about the middle, afterwards splitting unilaterally and becoming funnel-shaped; lobes reflexed, spathulate, acute, 3 1/2 lin. long, enlarged upper part lanceolate, 1 3/4 lin. long, nearly 3/4 lin. broad. Filaments inserted 3/4 lin. below the base of the corolla-lobes, slightly tapering upwards, 2 lin. long, at first connate round the style, afterwards separating, deflexed, tooth 1/4 lin. long; anthers narrowly oblong, nearly 1 lin. long. Disc about 1/6 lin. long. Style skittle-shaped above, thickened part 2 1/2 lin. long, neck 1 lin. long.
