Leaf blades about 14-18 x 4.5-6 cm, petioles very short or nil. Lateral veins about 8-12, forming loops inside the blade margin.
Calyx densely clothed in prostrate hairs on the outer surface, calyx lobes about 1 mm long. Corolla tube dilated in the upper half, about 15-20 mm long, lobes about 30 mm long. Anthers about 7 mm long; anthers included in the corolla tube.
Fruit ovoid, about 55-70 x 40-45 mm, circular in transverse section. Calyx lobes persistent at the apex. Seeds patelliform, about 6-8 x 6 mm. Embryo about 2 mm long. Cotyledons +/- orbicular, about 1.5 mm diam., much wider than the radicle.
Cotyledons cordate or orbicular, about 10-11 mm diam. First pair of leaves opposite. At the tenth leaf stage: leaf blade spathulate, +/- sessile, hairs on the outer surface at least along the midrib. Lateral veins forming loops inside the blade margin. Stipules interpetiolar, about 7 mm long, +/- encircling the twigs.
