Plant of unknown origin, cultivated in Vienna by Jacquin (not found at W). Description. Annual herb, commonly branched at the base with decumbent or ascending stems 5-25 cm long, vegetative parts glabrescent or shortly pubescent. Leaves 0.5-5 x 0.3-1.5 cm, oblong-oblanceolate, apex obtuse to rounded, margin entire, basal leaves gradually narrowed into a long petiole-like base up to 2 cm in length (so appearing spathulate), stem leaves abruptly narrowed at base, sessile and sometimes clasping and auriculate. Flowers solitary, subsessile in the axils of the upper leaves, becoming crowded towards the apex; peduncles and pedicels not clearly differentiated, 0-1 mm long; bracteoles filiform, minute; sepals 2.5-3.5 x 1.5-3 mm, narrowly elliptic to obovate, acute to rounded, thinly pilose; corolla 1-1.1 cm long, blue with a pale tube, distinctly lobed with triangular lobes, midpetaline bands pubescent, darkish; ovary long-pilose, style divided 1-1.5 mm above base, glabrous, stigmas 2 mm. Capsule pilose with stiff coarse hairs; seeds strongly tuberculate.
