Inflorescences lax, axillary, 1-4-flowered cymes; bracts 1 or 2, opposite. Calyx actinomorphic, 5-sect from base; segments equal. Corolla purplish, zygomorphic, inside sparsely puberulent toward apex of tube; tube nearly salverform, cylindric below, not swollen, slightly shorter than to nearly equalling limb, ca. 1.2 mm in diam.; limb 2-lipped; adaxial lip 2-sect from near base, slightly shorter than abaxial lip; abaxial lip 3-sect from near base, lobes equal, apex acute. Stamens 2, adnate to abaxial side of corolla tube above middle, included; anthers dorsifixed, coherent by adaxial surfaces, thecae divaricate, confluent at apex, dehiscing longitudinally; connective not projecting; staminodes 2, adnate to adaxial side of corolla tube. Disc ringlike. Ovary narrowly ovoid, 1-loculed; placentas 2, parietal, slightly projecting inward, 2-cleft. Stigma 1, terminal, disclike, undivided. Capsule straight in relation to pedicel, narrowly ellipsoid, nearly as long as calyx, dehiscing loculicidally to base; valves 4, straight, not twisted. Seeds unappendaged.
