Morphology General Habit
Annual ± erect herb, 4–30 cm. tall.
Morphology Stem
Stem usually much branched with widely spreading branches, ± hirsute.
Morphology Leaves
Leaves 10–55 x 4–25 mm., alternate, sessile to subpetiolate, narrowly oblanceolate to obovate or broadly elliptic to ovate, obtuse to subacute, rarely almost acuminate, with attenuate to cuneate base, ± hirsute; margin incrassate, undulate–dentate; midvein and lateral veins prominent beneath.
Morphology Reproductive morphology Inflorescences
Inflorescence lax, spreading; pedicels 5–20 mm. long, with very short but usually dense pubescence, often mixed with longer hairs.
Morphology Reproductive morphology Flowers Hypanthium
Hypanthium hemispherical, 5–nerved, ± hirsute.
Morphology Reproductive morphology Flowers Calyx
Calyx–lobes 1–3(5) mm. long.
Morphology Reproductive morphology Flowers Corolla
Corolla 1·5–4 mm. long, blue to pale blue or white, split almost to the base into lanceolate lobes, glabrous or hairy outside.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens with filament–bases ± rhombic, ciliate; anthers 0·5–1 mm. long.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 3–locular, semi–inferior; style c. as long as or longer than the corolla, thickened in the upper part, eglandular, subcapitate or shortly 3–lobed at the apex, glabrous or hairy below.
Morphology Reproductive morphology Fruits
Capsule 3–locular, 5–nerved; valves 3, 1–2·5 mm. long.
Morphology Reproductive morphology Seeds
Seeds 0·4–0·6 mm. long, elliptic in outline with acute ends, trigonous; testa almost smooth, brown or sometimes almost black.
