Passiflora lindeniana Planchon ex Triana & Planchon (1873: 182) ( Fig. 3F–H )

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