Morphology General Habit
Annual or short-lived perennial, erect to decumbent herb, 4–60 cm. tall, often purplish tinged towards the base.
Morphology Stem
Stem usually much branched, very narrowly winged or ribbed, sparsely to densely pubescent or occasionally glabrous.
Morphology Leaves
Leaves up to 5–40 mm. long, 4–30 mm. wide, linear to ovate or subreniform, narrowing upwards, obtuse to subacute at the apex, cuneate to cordate or rarely attenuate at the base, with a petiole up to 1.5–10(–15) mm. long, ± crenate to pinnatifid, densely pubescent to glabrous on both sides or only the upper side pubescent.
Morphology Reproductive morphology Flowers
Flowers in lax leafy racemes or rarely scattered in the upper leaf-axils; pedicels (10–)20–45 mm. long, filiform, glabrous or pubescent; upper bracts linear to elliptic or rarely ovate, usually much shorter than the pedicels; bracteoles 0.1–0.8 mm. long, at or near the base of the pedicel, rarely absent.
Morphology Reproductive morphology Flowers Hypanthium
Hypanthium broadly obconical, usually very short, glabrous or pubescent.
Morphology Reproductive morphology Flowers Calyx
Calyx-lobes very narrowly triangular, ± erect or spreading, (1.5–)2–5(–7) mm. long, entire, ciliate, ciliate-pubescent or rarely glabrous.
Morphology Reproductive morphology Flowers Corolla
Corolla 3.2–16 mm. long, blue to pale pink, split to 0.6–2 mm. from the base on the back, shortly pubescent to sparsely papillose inside, glabrous or pubescent on the lobes outside.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments, at least the 2 lower, pubescent below, rarely all subglabrous, all attached to the corolla-tube at the base.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther-tube 0.6–1.6(–2) mm. long, shortly pubescent at least on the back, or glabrous; 2 lower anthers each with a tuft of hairs and a hyaline appendage at the apex.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary subsuperior to semisuperior.
Morphology Reproductive morphology Fruits
Capsule ± obovoid, glabrous or pubescent, with prominent valves 1.5–3.2 mm. long, ± as long as or usually longer than the inferior part of the capsule.
Morphology Reproductive morphology Seeds
Seeds elliptic to broadly elliptic in outline, ± compressed, 0.3–0.5 mm. long, very finely striate, brown.
