Flowers about 15-17 mm diam. Calyx and corolla pubescent on the outer surface. Sepals less than 0.5 mm long, densely hairy, fused into a cupule. Petals about 15-17 x 2 mm, hairy on the outer surface and shortly fused at the base. Anthers linear, about 7-8 mm long, filaments about 5-7 mm long, hairy. Style about 5-6 mm long.

Fruits spindle-shaped, 20 x 9-10 mm, puberulous. Seeds about 17 x 7 mm.

Cotyledons ovate or elliptic, about 25-35 x 15-22 mm, apex obtuse, base obtuse. First pair of leaves elliptic, upper and lower surfaces hairy, foveoles present along the midrib and major lateral veins close to the leaf blade margin. At the tenth leaf stage: leaves hairy on both the upper and lower surfaces, small foveoles present. Seed germination time 28 to 38 days.
