Passiflora emarginata Bonpland (1808: 23) ( Fig. 3B–C )

Pollen grains large, oblate spheroidal ( Table 1), polar area large ( Table 2), amb subcircular, colpi long, narrow, endoaperture lalongate, pontoperculum ( Table 3) reduce the width of the apocolpium; sexine reticulate, heterobrochate; muri simplecolumellate, sinuous, continuous, with perforations, without high columellae, not apparent, tectum surface mostly curved, lumina ornamented; there is no difference in the diameter of the lumina of the apocolpium and the mesocolpium; sexine thicker than nexine ( Table 4).
