Annual or perennial occasionally suffrutescent erect to suberect herbs or rarely small dwarf shrubs (6)10–60(100) cm. tall, with woody base to 5(10) mm. in diam.; stems ± quadrangular, papillose, scabrid or glabrous, becoming glabrous towards the top, often with sparse rounded papillae along ridges. Leaves (10)16–40(65) x (0.4)0.6–1.5(2) mm., filiform to narrowly linear, rarely narrowly linear-lanceolate, apex acute, very slightly narrowed to the base, margins mostly revolute, ± glabrous or lower surfaces especially midrib and margins with rounded loosely arranged papillae, numerous short shoot leaves often giving nodes a fasciculate appearance; stipular sheath (0.5)0.6–1.5(1.7) mm. long, glabrous, stipular lobes 0.4–1.2(2) mm. long. Inflorescences ± spreading, 1 or mostly 2 flowers at a node, one subsessile, the other pseudo-pedicellate; peduncles (2) 10–45 mm. long; pseudo-pedicels 3–12(20) mm. long; glabrous, scabrid or ± verrucosely papillose. Calyx tube (0.8)1–1.6(1.8) x (0.7)1–1.5(1.7) mm., hemispherical to ± ovoid, glabrous or minutely verrucose; lobes (0.5)1–2(2.5) mm. long and 0.2–0.6 mm. wide at the base, broadly to narrowly triangular, rarely ± ovate-lanceolate, glabrous or ± scabrid with minute papillae along margins and midribs or minutely verrucose occasionally with short filiform elements on either side. Flowers scented during late afternoon and evening; corolla lobes above white, cream, more rarely pinkish mauve, tube and lobes darker below—brown, reddish brown, olive green, olive brown or dirty cream, glabrous or outside of dilated tube and midvein on back of lobes with sparse small round papillae; tube altogether (8.5)9.6–14.2(16) mm. long, the widened part (1.4)1.5–2.6(3.4) x 1–1.8(2) mm., the narrow part (0.4)0.5–1 mm. wide; lobes 2.8–5.8(7) x (0.8)1–2(2.5) mm., narrowly oblong to ovate, not quite parted to the base, ± acute. Anthers narrowly ovate, c. 1–2.2 mm. long, often sterile, connectives darkly discoloured; pollen 3- (very rarely 4-)colporate. Style 1.5–2.6 mm. long; stigma lobes 1.4–2.6 mm. long. Capsules (1)2.2–3 x (2.2)2.8–3.8(4.3) mm., obconic-hemispherical rarely subglobose, glabrous or slightly scabrid. Seeds brown c. 0.6 mm. long, angular-subconic.
