Morphology General Habit
Annual erect herb, 10–55 cm. tall, from a white taproot.
Morphology Stem
Stems few to many, glabrous or sometimes sparsely hirsute or puberulous towards the base.
Morphology Leaves
Leaves up to 25–130 x 6–18 mm., ± rosulate, flat, narrowly obovate to narrowly oblanceolate or spathulate, acute to subacute with attenuate base often narrowing into a distinct petiole, ciliate towards the base, 4 hirsute on both sides or only above, or glabrous; margin not or very slightly incrassate, ± dentate, sometimes pinnately lobed at least towards the base; midvein prominent beneath, lateral veins faint.
Morphology Reproductive morphology Inflorescences
Inflorescence lax; pedicels up to 14–45 mm. long, glabrous; bracts and bracteoles usually ciliate at least towards the base.
Morphology Reproductive morphology Flowers Hypanthium
Hypanthium obovoid to hemispherical, c. 10–nerved, glabrous.
Morphology Reproductive morphology Flowers Calyx
Calyx–lobes 1–2–5 mm. long, narrowly triangular, entire, glabrous.
Morphology Reproductive morphology Flowers Corolla
Corolla 5–10 mm. long (forms with larger corollas, up to 22 mm. long, that probably belong here, occur in S. Africa and Namibia), pale blue or mauve, widely campanulate to almost rotate, deeply 5–lobed; tube 1–2 mm. long, puberulous inside near the base.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens with filament–bases broadly dilated to almost cross–shaped, shortly ciliate; anthers ± 2–2·5 mm. long.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 3–locular, subinferior; style somewhat shorter than the corolla, hairy or glabrous below, 3–lobed, with 3 glands present below the pollen–collecting hairs.
Morphology Reproductive morphology Fruits
Capsule 3–locular, c. 10–nerved; valves 3, 0·8–1–2 mm. long.
Morphology Reproductive morphology Seeds
Seeds 0·4–0·6 mm. long, elliptic in outline, ± compressed; testa almost smooth.
