This genus is characterised by inaperturate and spinose pollen grains that are united in loose tetrahedral tetrads (groups of four). The grains are prolate, striate, and tricolpate. The colpi are slender and long, whereas the striae are very fine, densely packed, and situated parallel to the polar axis.[6]
