Flowers pedicellate. Calyx lobes linear-triangular, about 5-6 mm long, sparsely hairy. Corolla about 7-8.5 mm long, tube red-spotted and somewhat hairy on the inner surface. Stamens included in the corolla tube, anthers maroon, locules attached side by side, connective extending slightly beyond the anthers.
Cotyledons orbicular to reniform, about 7-10 x 8-10 mm, usually wider than long. First pair of leaves often with a slender spine in one of the axils. At the tenth leaf stage: leaves opposite but the leaves in each pair are very unequal in size, one always much larger and wider than the other. Axillary spines about 3-4 mm long, produced in the axil of the smaller leaf in each pair. Leaf blades with one or two coarse teeth on each side. Lateral veins forming loops well inside the blade margin. Stems +/- square in transverse section. Seed germination time 12 days.
