The surface is reticulate-foveolate or coarsely reticulate, with an average of 5.60 reticulations per mm 2 . The reticulations have an average diameter of 487 µm and a depth of 190 µm. The margin is striate or entire, sometimes with a lateral fold. The apex may have a prominent appendage. The base is obtuse or acute, sometimes truncate, and may have a mucro. The palisade seed coat is on average 230 µm thick. Remark The genus is represented by 12 species, 8 are studied here.
