- Diagnosis
- Fruit elongate ellipsoidal in outline, incomplete length of fruit 62 mm, width 15 mm. One end rounded, the other end broken, lateral margins smoothly convex, outer surface smooth. Texture inferred to have been leathery. Fruit apparently dehiscing in two valves, with two dense rows of subopposite seeds exposed (more than 8 per row, complete number unknown), seeds attached to a thickened axial structure (placental strand). Seeds borne on short stout funicles arising from the central placental strand. Placentation apparently axile. Inner surface of dehisced valve with striate margin (1.3– 2.1 mm broad) otherwise smooth; width of locular area 12 mm. Seeds obovate, smooth, with a distal elliptical structure (most probably chalaza) about 1.5–2 mm in diameter. No wings observed.
