- Diagnosis
- Fruit obovate, 30–32 mm long, 19–24 mm wide, 5.5 mm thick, unilocular. Longitudinally ridged; with 7–10 main ridges per face, ridges from 2–7 mm wide. Ridge prominence diminishing towards the rounded, funicular end. Ridges anastomosing about halfway from the narrowed end, having fewer anastomoses and more elongate meshes at the opposite end; frequent anastomoses delimiting more isodiametric, polygonal meshes. Longitudinally aligned fibers occur only on the ridges. Other surface cells within the meshes black and shiny, some longitudinally elongate, others isodiametric, ca. 20–60 μm in length. Asymmetrical bulge with a horizontally elongate mouthlike scar near the apex. Fruit wall uniform, ca. 1 mm thick composed of dense “parenchymatous” tissue (not fibrous). Locule filled with tissue of isodiametric cells larger than those of the surrounding fruit wall.
