Seed description Seeds compressed, 5.0 mm long, 2.9 mm wide and 1.4 mm thick, oblong. The surface is reticulate-foveolate and light cream, with 6.12 reticulations per mm 2 . The reticulations have an average diameter of 458 µm and a depth of 173 µm. The margin is entire with a very pronounced fold. The apex lacks a prominent appendage. The base is acute, with a mucro. The palisade seed coat is 221 µm thick.
