Diagnosis
Fruit single-seeded, mature length 17.4– 25.8 mm, width 8.0–12.6 mm (n = 12), immature length 9.2 mm, width 4.0 mm (n = 1), frequently with persistent calyx, rarely seen in process of detachment of calyx, and commonly encountered lacking the calyx. Calyx of two whorls each of three segments, fibrous and longitudinally striate, covering one third to a quarter of the whole fruit, calyx length 6.1–7.7 mm, width 5.8–7.6 mm (n = 5). Outer whorl of calyx one third to one half the length of the inner whirl. Fruit usually elliptical, sometimes ovate, with persistent short conical style (2–4 mm) protruding from a rounded apex. Outer fruit wall fibrous, in some cases fibres spreading as a result of degradation (SM.B Me 2123, pl. 5f). Seed structure was revealed by dissection of three specimens (pl. 5j–l). At the stylar end, large (3–4 mm) diameter circular hilar/chalazal plug, raphe extending from central protrusion down the full length of the seed to the attachment end. Fibrous bands (seen as grooves) radiate from the raphe. A single specimen (pl. 5m) reveals the hilar/chalazal plug through the partially degraded fruit wall.
