The fossil record indicates that tricolpate pollen originated
The tricolpate pollen of some Saxifragaceae, as well as that of Gunnera, suggests that they occupy a basal position among eudicots in light of evidence for the monophyletic origin of tricolpate pollen (Doyle & Hotton, 1991; Chase et al.
by its large size, its short, wide, tricolpate aperture, and its solid
