Passiflora chlorina Escobar (1989: 132) ( Figs. 2L , 3A )

Pollen grains medium-sized, oblate spheroidal ( Table 1), polar area small ( Table 2), amb subtriangular; colpi long, narrow, endoaperture lalongate, pontoperculum ( Table 3) reduce the width of the apocolpium; sexine reticulate, heterobrochate; muri simplecolumellate, straight to sinuous, continuous, with perforations, without high columellae, 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).
