Type
Type: Nigeria, without locality, P. Beauvois s.n. (G!, holo.)
Morphology General Habit
Ascending herb, sometimes a simple annual (see note), up to 40 cm high.
Morphology Stem
Stems fleshy, trailing, rooting at nodes, glabrous or nearly so
Morphology Leaves
Leaves lanceolate to ovate, 1.5–4(–8) cm long, (0.2–)0.6–1.2(–2.3) cm wide, narrowed at the base into a short petiole or sessile or base amplexicaul, obtuse to acute at apex, margins crenateserrate, glandular-punctate
Morphology Reproductive morphology Flowers
Flowers solitary in most leaf axils; pedicels 1–3(–5) mm long
Morphology Reproductive morphology Inflorescences Bracts
Bracts 2, 1.5 mm long, setaceous
Morphology Reproductive morphology Flowers Calyx
Calyx glabrous, the outer lobes broadly ovate, posterior lobe largest, 8–9 mm long and 4–5 mm wide, in fruit reticulate-veined; other lobes successively smaller and narrower, lateral lobes somewhat keeled
Morphology Reproductive morphology Flowers Corolla
Corolla pure white with yellow mark in the throat, slightly longer than the calyx; upper lip emarginate, lower lip equally 3-lobed.
Morphology Reproductive morphology Flowers Gynoecium Style
Style and ovary glabrous
Morphology Reproductive morphology Fruits
Capsule 3–4 mm, ovoid, glandular
Morphology Reproductive morphology Seeds
Seeds ellipsoid.
Ecology
Grassy swamps and salt marshes; 0–1600 m
Conservation
Least Concern (LC); widespread
Note
Typically this species has a stout ascending stem and rooting habit, but in brackishmarshy habitats it tends to be a small annual with a simple erect stem; these are ecotypes and cannot be considered as separate taxa.
