Shape, Size and Aperture

pollen unit: monad,  dispersal unit and peculiarities: monad,  size (pollen unit): small (10-25 µm),  pollen class: colporate,  polarity: isopolar,  shape: spheroidal,  outline in polar view: circular,  shape (dry pollen): prolate,  outline in polar view (dry pollen): lobate,  infoldings (dry pollen): aperture(s) sunken,  aperture number: 3,  aperture type: colporus,  aperture condition: colporate, tricolporate,  aperture peculiarities: -

Ornamentation and Structure

LMornamentation LM: -,  nexine: -,  sexine: -,  SEMornamentation SEM: perforate,  TEMtectum: eutectate,  infratectum: columellate,  foot layer: continuous,  endexine: compact-continuous,  intine: monolayered,  wall peculiarities: -

Miscellaneous

Annotations

endexine thin and sometimes discontinuous;

the crumpled exine surface is probably an artefact
