Annual herb, stems 1 to several tufted from the base, 70-150 mm long (possibly up to 200 mm in fruit), erect or decumbent, simple to sparingly branched at the base, lower part glandular-puberulous, hairs up to 0.4-0.5 mm long, mixed with balloon-tipped hairs upwards, these up to 0.3 mm long, apical cell c. 0.05 mm in diameter, gland-tipped hairs up to 0.2 mm long, leafy particularly near the base, branches or incipient branches in the axil of a reduced leaf. Leaves opposite, bases connate, blade (of principal leaves) c. 15-26 x 6-13 mm, broadly to narrowly elliptic in outline tapering to a long flat petiolar part c. 7-15 mm long (about equalling to 1/3 as long as the blade), apex ± obtuse, margins serrate to lyrate, these lobes toothed again, both surfaces glandular-puberulous, hairs up to 0.4-0.6 mm long. Flowers many in a long lax terminal raceme, usually solitary or sometimes paired in the axil of each bract. Bracts (lowermost) 1.5-6 x 0.4-0.7 mm, lanceolate or oblong-lanceolate, or occasionally lowermost flower subtended by a much reduced leaf. Pedicels (lowermost) 1-5 mm long. Calyx very obscurely bilabiate, tube 0.3-0.4 mm long, lobes 2.2-2.7 x 0.4-0.6 mm, lanceolate, acute, puberulous all over with mainly balloon-tipped hairs up to 0.25-0.5 mm long (apical cell up to c. 0.05 mm diam.) mixed with glandular hairs up to 0.3 mm long. Corolla tube 3.5-3.75 x 0.8-0.9 mm in throat, cylindric, expanded near apex, limb bilabiate, 6.5-8.5 mm across the lateral lobes, which ascend, leaving the anticous lobe somewhat isolated, posticous lobes 4-5 x 0.6-0.8 mm, anticous lobe 2.6-3.5 x 0.5-0.6 mm, all lobes long-lanceolate, margins revolute, lobes subulate to eye, orange, back of tube also orange, tube and backs of lobes puberulous with balloon-tipped hairs up to 0.1-0.2 mm long, inside with 3 longitudinal bands of clavate hairs on posticous side, lesser band on anticous side. Stamens 4, anticous anthers 0.25-0.3 mm long, tips just visible in mouth, posticous anthers 0.6-0.7 mm long, included; posticous filaments bearded. Stigma 0.7-0.9 mm long, included, tip sometimes bifid. Style 0.3-0.5 mm long. Ovary 0.9-1 x 0.7-0.8 mm. Capsules not seen.
