The Pollen Morphology of Moringaceae
Kew Bulletin, 1985The pollen morphology of 13 species of the genus Moringa has been studied. The pollen exine is rather distinctive and uniform in structure throughout the family. It is spheroidal, tricolporate with costate colpi, the ornamentation is psilate with sparse puncta, the endexine is very thick at the apertures but almost absent from the mesocolpial and polar

Pollen morphology of the Onagraceae
Review of Palaeobotany and Palynology, 1967Abstract This incomplete but comprehensive survey based upon the pollen of 21 genera and over 100 species of the Onagraceae shows the following pollen types: 1. ( 1 ) Pollen in tetrads and disarticulated tetrads. The single grains usually have a thicker ring at the base of the somewhat aspidote pore. This condition occurs in Epilobium (in part),
