Pollen Description

Shape, Size and Aperture

pollen unit: monad,  dispersal unit and peculiarities: monad,  size (pollen unit): medium-sized (26-50 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: -,  polarity: isopolar,  P/E-ratio: -,  shape: spheroidal,  outline in polar view: circular,  dominant orientation (LM): -,  P/E-ratio (dry pollen): prolate,  shape (dry pollen): -,  outline in polar view (dry pollen): lobate,  infoldings (dry pollen): aperture(s) sunken,  aperture number: 3,  aperture type: -,  aperture condition: colpate,  aperture peculiarities: aperture membrane ornamented

Ornamentation and Structure

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

Miscellaneous

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

Annotations: The difference between the pollen grains of the two morphs short-styled (SS) and long-styled (LS) is only in kind of ornamentation. SS: baculate LS: clavate
