- Diagnosis
- Endocarp bilaterally symmetrical, unilocular, single-seeded, elliptical to ovate, with a reticulate pattern of sharp and sinuous idges, which delimit about 17 polygonal areoles on each face with few
or no freely ending ridgelets. A keel surrounds the endocarp in the plane
of symmetry with the thicker margin containing a vascular bundle
embedded in the endocarp wall. Endocarp possessing an apical outgrowth composed of the main ridge that runs from the base up to the
apex and a protuberance from the keel merged. Endocarp wall about 0.08–0.19 mm thick excluding ridges (0.18–0.39 mm including ridges).
Inner endocarp surface densely covered with regularly spaced more or
less punctuated and sessile rounded papillae. Length of endocarp
about 5.8–8.0 mm, width about 3.61–5.42 mm.
