Leaves in whorls of 3–4; blades 1–6.5 × 0.4–2.8 cm, rounded elliptic to narrowly elliptic, narrowly oblong or oblanceolate, rounded to bluntly acute at the apex, cuneate to almost rounded at the base, glabrous or rarely pubescent, usually drying pale olive-green; petioles 1–2 mm long; stipules connate at the base, oblong-triangular, 3–4 mm long including a shortly to distinctly produced apex.
Corolla obtuse in bud; white or pale to bright yellow or greenish-yellow, glabrous; tube 3–4 mm long, cylindrical-campanulate, with ring of deflexed hairs inside; lobes 4–6(7), 3–5 × 2.5–2.8 mm, triangular-oblong or ovate, cucullate but scarcely apiculate at the apex, glabrous save for papillate margins and inner surface.
A pyrophytic, usually glabrous, suffrutescent herb, 6–40 cm tall, with a single or usually several rather short unbranched stems from a slender creeping woody rhizome; stems glabrous, or with rather sparse bristly hairs in a very few specimens; lowest nodes usually leafless.
Inflorescences (1)3-flowered, sweet-scented, borne at the lower nodes, sometimes flowering before the leaves are produced; peduncles 5–20(30) mm long and pedicels 1.5–6.5(10) mm long, both glabrous or sparsely pubescent, sometimes flowers solitary on stalks up to 16 mm long.

Calyx tube 2–2.5 mm long, the narrow limb almost membranous, truncate, erose or slightly to distinctly narrowly toothed; teeth 0.7–1.2 mm long.
Fruit red at maturity, 7–9 × 9–10 mm, globose, or often drying very distinctly 2–3-lobed.
Pollen presenter green, coroniform, 3–4-lobed.
Style 5.5–6 mm long.
