Morphology General Habit
Annual erect herb, 5–40 cm. tall.
Morphology Stem

Morphology Leaves
Leaves up to 15–40 x 10–24 mm., broadly ovate, gradually narrowing upwards, usually acute at the apex, gradually or abruptly narrowing below into a petiole–like base, serrate–dentate, sparsely pubescent on both sides; venation prominent beneath.
Morphology Reproductive morphology Flowers
Flowers in lax terminal and axillary leafy racemes; pedicels up to 6–20 mm. long, finely papillose; upper bracts linear or lanceolate, equalling or shorter than pedicels; bracteoles 0·5–1 mm. long, linear, at the base or near the middle of the pedicel.
Morphology Reproductive morphology Flowers Hypanthium

Morphology Reproductive morphology Flowers Calyx
Calyx–lobes narrowly triangular, completely reflexed after the anthesis, 1·6–5 mm. long, c. 1 mm. wide at the base, entire, ciliate.
Morphology Reproductive morphology Flowers Corolla
Corolla 4·5–6·5 mm. long, pale blue, pale mauve or white with darker markings, split to c. 1 mm. from the base on the back, glabrous or papillose inside on the bottom of the tube.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments linear, all glabrous or the two lower pubescent below, attached to the corolla–tube at the base.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther–tube 0·6–1 mm. long, glabrous or with a few short hairs on the back; the two lower anthers each with a tuft of hairs and a hyaline appendage at the apex.
Morphology Reproductive morphology Flowers Gynoecium Ovary
