Ornamentation and Structure

LMornamentation LM: -,  nexine: -,  sexine: -,  SEMornamentation SEM: echinate, microbaculate,  TEMtectum: eutectate,  infratectum: -,  foot layer: -,  endexine: -,  intine: -,  wall peculiarities: -

Miscellaneous

Annotations

The 2 apertures are situated in the equator and parallel to it, therefore the aperture condition is disulcate and not dicolpate (in this case the apertures are orientated meridionally); the shape of hydrated pollen is oblate with elliptic outline to spheroidal
