Diascia alonsooides Benth.

Annual herb, main stem c. 150-400 mm long, up to c. 2 mm diam., branching from the base, erect or decumbent, glabrous, becoming glandular-puberulous on the inflorescence axis. Leaves in 3-4 pairs on each branch, c. 15-30 x 7-21 mm, ovate, apex subacute, base ± truncate to subcordate-cuneate, margins subentire to sharply serrate, glabrous, or with a few gland-tipped hairs below on the margins and veins near the base; petioles sparsely glandular-puberulous, up to 15 mm long, length rapidly decreasing upwards, uppermost leaves subsessile. Flowers many in terminal racemes, loosely panicled; lowermost bract leaf-like, c. 4 x 9 mm, the upper ones becoming smaller, ovate-lanceolate, shortly acuminate, base cordate-clasping, lower surfaces glandular-puberulous; pedicels up to c. 20 mm long, filiform, glandular-puberulous, often somewhat spreading, then tips upcurved in fruit. Calyx segments lanceolate, acute, anticous pair c. 2.5 x 0.75-1 mm, three posticous ones slightly smaller, a few small gland-tipped hairs near the base. Corolla subrotate, slightly bilabiate, without pouches or spurs, c. 12 mm diam., anticous lobe c. 4.5 x 5 mm, two lateral lobes c. 4 x 5 mm, two posticous lobes c. 5 x 4 mm, joined for half their length, all subrotund, probably rose-pink, glabrous and without dark sessile glands; “windows” two, one at the base of each posticous lobe, ± ovate in outline. Stamens projecting forward, filaments of the anticous pair 2 mm long, of posticous pair c. 4 mm, sharply bent c. 1 mm from the apex and strongly thickened there, all villous; anticous anthers c. 0.75 mm long, posticous ones a trifle smaller, all four cohering strongly. Ovary 1 x 0.75 mm, ovules many in each loculus, style 2 mm, stigma capitate, lying between the anthers. Capsule c. 7 x 2 mm, oblong-elliptic in outline; seeds c. 1 mm long, curved, ridged.
