- Diagnosis
- Seed ovoid, length 3.5–8.4 mm, width 1.5– 3.6 mm, with length/breadth ratio from 1.5–2.3 (n = 14). Seed with one end more or less pointed, sometimes appearing beaked and opposite end more rounded and often faceted. Seed slightly laterally compressed, with a smooth, slightly shiny surface. Surface sculpture microscopic pattern of polygonal cells (especially near hilum) to elongated cells with inflated outer periclinal walls. Elongate cells forming longitudinally striate surface pattern, cells ranging up to 0.2 mm long by 0.04 mm wide. More truncate end of the seed with a recessed hilar scar (0.6–1 mm wide, n = 4), trough-like and ligulate-ovate passing slightly over the end of seed, where it reduces in width to a narrow slit (0.1 mm wide), but not descending down opposite side. Scar extending for one third to one half of the length of the seed. A slight facet is seen on the face opposite the hilar scar but the seed coat surface is not modified over the facet.
