Palynology after Y2K—understanding the source area of pollen in sediments. The groups are mentioned as N1 to N7. Fertilized seeds grow into adult plants, not intermediate gametophytes. Hemsley: Heterospory: cul-de-sac or pathway to the seed? Jarvis: Underwater pollination, three-dimensional search, and pollen morphology: predictions from a supercomputer analysis.

Katifori, E. The character groups of pollen and spore are seven and they are mentioned as C0 to C6. Google Scholar Gordon, A. The group C5 comprises colporate pollen. Developmental bases for key innovations in the seed-plant microgametophyte. The characters of stamen were the basis of classification.

References Bakker, S. Pollen grains having one leptoma are termed as monlept. As for example the family Gramineae seems to be closely related to Restionaceae, Centrolepidaceae and Flagellariaceae, because pollen grains of above taxa are monoporate. NPC characterizes those pollen grains that are polytreme pantoporate, which are also described as pantoporate or polyporate.
