Original diagnosis/description

Seed broadly winged; main seed body (without wing) ovate to broadly ovate in outline, rounded to slightly concave at the chalazal end of the seed and gradually tapering into an acuminate micropylar area; raphe sinus lacking or only weakly developed. Outer surface of seed smooth with circular tubercles (secretory cells) irregularly scattered over the main seed body; heteropyle simple, wide, and more or less triangular in shape. Surface of wing with fingerprint-like pattern. Surface of endotesta with a faint striate pattern. Endotesta thin, with one layer of palisade-like sclerenchyma cells, each with imprints of cubic crystals.


From Lat. tenuis (thin, slender) referring to the thin testa of the seed wall.
