Pollen Description

Shape, Size and Aperture

pollen unit: monad,  dispersal unit and peculiarities: monad,  size (pollen unit): large (51-100 µm),  size of hydrated pollen (LM): -,  shortest polar axis in equatorial view (LM): -,  longest polar axis in equatorial view (LM): -,  shortest diameter in equatorial or polar view (LM): -,  longest diameter in equatorial or polar view (LM): -,  pollen class: colporate, inaperturate,  polarity: isopolar,  P/E-ratio: -,  shape: spheroidal,  outline in polar view: circular,  dominant orientation (LM): -,  P/E-ratio (dry pollen): -,  shape (dry pollen): spheroidal,  outline in polar view (dry pollen): circular,  infoldings (dry pollen): not infolded,  aperture number: >6,  aperture type: porus,  aperture condition: porate, pantoporate,  aperture peculiarities: pantoaperturate

Ornamentation and Structure

LMornamentation LM: -,  nexine: -,  sexine: -,  SEMornamentation SEM: echinate, granulate,  suprasculpture SEM: -,  TEMtectum: -,  infratectum: -,  foot layer: -,  endexine: -,  intine: -,  wall peculiarities: -,  supratectal element: -

Miscellaneous

pollen coatings: -,  reserves in cytoplasm: -,  cell number: -,  Ubisch bodies: absent

Annotations: exine ruptures easily especially near the pores though the pollen grains seem to be pantocolpate
