Leaves linear, often slightly curved, 0.8-2.5 (-3) cm long, 0.8-1.4 mm wide, crowded on suppressed or very short lateral branchlets in clusters of 3; upper surface with longitudinal veins prominent and usually granular; margins shortly twice-refracted about intramarginal vein, with the first refraction forming a short vertical wall perpendicular to the topological upper surface, the second at 90º again (leaf oblong in cross-section); lower surface usually partly exposed and subsericeous, occasionally enclosed. Conflorescence erect, terminal, sessile, regular, umbelloid, c. 8-20-flowered. Flowers adaxially acroscopic. Flower colour: perianth pale green to cream or white, with brown hairs on limb; style white to pale pink, becoming reddish later. Perianth subsericeous outside, with a scanty beard inside opposite ovary. Pistil 6.5-7 mm long; style strongly hooked in apical 3 mm, with minute hairs or papillae in apical 1 mm; pollen-presenter oblique. Follicle narrowly ellipsoidal, c. 9 mm long, faintly warty.
