Morphology General Habit
Perennial (? rarely annual) erect herb, 9–60 cm. tall, with few to many rather slender strict or spreading branches from a woody base; stems glabrous, scabridulous or quite densely pubescent with short spreading hairs.
Morphology Leaves
Leaf-blades linear to narrowly elliptic, 1–4 cm. long, 0.5–5 mm. wide, acute and often, particularly in wider leaves, ending in a seta up to 1 mm. long, gradually narrowed at the base, glabrous to quite densely covered with spreading hairs at least above and on margins and midvein beneath; stipule-sheath 1–2 mm. long, divided into 2–6 filiform fimbriae (1–)2–6 mm. long.
Morphology Reproductive morphology Inflorescences
Inflorescences lax, with 2–several flowers at each node, some with short pedicels others long, those in the lower parts of the inflorescence actually axillary but the leaves reduced to stipules only which form hyaline bracts; peduncles 0.1–3(–6) cm. long, internodes of inflorescence 0.6–3.3 cm. long; pedicels 1–9(–18) mm. long, glabrous.
Morphology Reproductive morphology Flowers Calyx
Calyx-tube subglobose, ± 1 mm. long, 1.5 mm. wide, glabrous; lobes narrowly triangular, 1.2–2 mm. long, ending in a short seta, glabrous or somewhat scabridulous on the margins.
Morphology Reproductive morphology Flowers Corolla
Corolla white to purplish brown with lobes white, pale rose, red or lilac (sometimes only at the apex outside); tube 3.5–5.5 mm. long, the widened part 1–1.3 mm. long, 0.9–1.2 mm. wide, glabrous outside and throat not bearded within; lobes ovate-elliptic, 0.9–1.9 mm. long, 0.8–1.2 mm. wide, ± acute.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Style 2.5–3.5 mm. long; stigma-lobes 1.2–1.4 mm. long.
Morphology Reproductive morphology Fruits
Capsule transversely oblong or subglobose, 1–2 mm. long, 1.5–3 mm. wide, glabrous; fruiting pedicel up to 1.3 cm. long.
Morphology Reproductive morphology Seeds
Seeds dark brown, subconic to irregularly ovoid, ± 0.3 mm. long.
Habitat
Open grassy places in coastal bushland, deciduous woodland, secondary grassland, rocky places, waste ground, roadsides and in old cultivations and rice fields; 0–1080(–1620) m.

Morphology Reproductive morphology Inflorescences
Inflorescences usually with 2 or, more rarely, 3 with additional accessory, flowers at a node, pedicellate or rarely subsessile; peduncles (3)24–34(79) mm. long; pedicels (1)3–7(15) mm. long, glabrous.
Morphology Reproductive morphology Flowers Calyx
Calyx tube (0.5)0.7–1.3(1.5) x (0.4)0.9–1.4(1.6) mm., obovate-subglobose glabrous; lobes narrowly triangular to narrowly ovate-triangular, ending in a short seta or mucro, margins with short stiff hairs, otherwise glabrous.
Morphology Reproductive morphology Flowers Corolla
Corolla lobes variously coloured, white, cream, yellowish, blueish, mauve, purple, pink or red, sometimes bicoloured on the same plant; buds usually darker in colour (red or pink), open flowers becoming paler with age?; back of lobes and tubes paler or brownish to pinkish green or greenish white, interior and exterior glabrous or very rarely in longer tubed forms throat inside very slightly papillose; tube altogether (2.7)3–6.5(7) mm. long, the dilated part (0.7)1–2.1(2.4) x (0.7)0.8–1.2(1.45) mm., the narrow part (0.4)0.5–0.9(1.1) mm. wide; lobes (0.9)1–2.2(2.4) x (0.6)0.8–1.2(1.3) mm., ovate-triangular to ovate-elliptic, subacute to slightly apiculate.
