Pollen grains in Ruellieae, particularly in Strobilanthinae (including Strobilanthes s.l.) exhibit great diversity and are most eurypalynous in the family. In light of the aperture types and exine ornamentation patterns, pollen grains of the genera examined fall into three major types: 1. 3-porate pollen, which includes, (1) pollen with reticulate exine ornamentation (Pararuellia); (2) pollen with gemmate exine ornamentation (Championella); (3) pollen with echinate exine ornamentation (Paragutzlaffia, Diflugossa and Pteroptychia). 2. 3-colporate pollen or 3-colporate pollen with pseudocolpi, which includes, (1) 3-colporate pollen with reticulate exine ornamentation (Eranthemum and Barleria); (2) 3-colporate pollen with pseudocolpi and ribbed or banded, and septate exine ornamentation, the lumina rounded, finely reticulate inside and arranged in longitudinal rows (Perilepta, Pteracanthus, Goldfussia, Sympagis an
