Description
Branchlets subangular to angular, thick, 8-10 mm diam., sulcate when dried, smooth, not lenticellate, glabrous, with conspicuous leaf scars.
Leaves in whorls of 4-6(-7), coriaceous to thickly so when dried, long petiolate;
Inflorescence 9.5-18.5 cm long, terminal and axillary cymes, in whorls of 2-5, congested, glabrous;
Flowers more than 30 on each inflorescence, fairly long pedicellate;
Sepals suborbicular to orbicular, 2.1 by 2.1 mm, ratio 1, margin entire to undulate, apex blunt, rather thin except at the middle-basal part, rather rough outside, smooth inside, glabrous, connate at base for 0.6 mm.
Stamens inserted at 8 mm below the mouth, 0.2 of the length of the corolla tube;
Ovary ovoid, widening at base, apex rounded and abruptly narrowed at base of style, 1 by 1 mm, of 2 distinctly separated carpels.
Morphology
Specimens with fruits are not available. Therefore, the position of this species at the sectional level is still unknown. It is characterised by the absence of a submarginal vein, its suborbicular to orbicular sepals and the insertion of stamens near the base (only 0.2 of the length of the corolla tube).
