Passiflora jussieui Feuillet (2010: 611) ( Fig. 1E–G )

Pollen grains large, prolate spheroidal( Table 1), polar area large ( Table2), amb circular;colpi short, narrow,endoaperture lalongate, pontoperculum ( Table 3) does not reduce the width of the apocolpium; sexine partially tectate as small pieces of remnant muri can be observed; muri duplicolumellate, columellae high, apparent, without perforations and most of the tectum surface is curved or with spines (ca. 4.8 × 4.6 μm) ( Fig. 1G ), not forming lumina ( Table 3). A large part of the surface is ornamented with sparsely distributed bacula and conspicuous pila; sexine thicker than nexine ( Table 4).
