Original diagnosis/description

Ovary and fruit narrowly elongate. Glandular trichomes restricted to the hypanthium, typically arranged in three longitudinal rows near the top of the ovary. Simple trichomes on the surface of ovary, calyx, filaments and styles. Dimensions: Flower bud with calyx completely covering corolla: total length: 0.85 mm; length of ovary: 0.35 mm; maximum breadth of the ovary: 0.3 mm. Flower buds with corolla extending beyond calyx: total length: 1.9–2.25 mm; length of ovary: 1.05–1.2 mm; maximum breadth of ovary: 0.35–0.4 mm. Larger specimens without corolla: length of ovary/fruit: 1.5(1.88)2.2 mm; breadth of ovary/fruit: 0.55(0.67)0.9 mm; length of sepals: 0.9–1.0 mm; breadth of sepals: 0.25–0.3 mm. 15 specimens were measured. Pollen: length about 13 μm; equatorial diameter about 10 μm.
