Pollen Description

Shape, Size and Aperture

pollen unit: monad,  dispersal unit and peculiarities: monad,  size (pollen unit): small (10-25 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,  polarity: isopolar,  P/E-ratio: isodiametric,  shape: spheroidal,  outline in polar view: circular,  dominant orientation (LM): -,  P/E-ratio (dry pollen): oblate,  shape (dry pollen): -,  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: aperture membrane psilate

Ornamentation and Structure

LM  ornamentation LM: -,  nexine: -,  sexine: -,  SEM  ornamentation SEM: reticulate,  suprasculpture SEM: -,  TEM  tectum: -,  infratectum: -,  foot layer: -,  endexine: -,  intine: -,  wall peculiarities: -,  supratectal element: -

Miscellaneous

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

Annotations: The colpi are long with distinct margin. The pori are almost as big as the colpi and can be clearly seen in dry condition. In hydrated condition, pollen may therefore be misinterpreted as colpate.
