Pollen Description

Shape, Size and Aperture

pollen unit: tetrad,  dispersal unit and peculiarities: tetrad,  size (pollen unit): medium-sized (26-50 µm),  pollen class: -,  polarity: heteropolar,  shape: spheroidal,  outline in polar view: circular,  shape (dry pollen): oblate,  outline in polar view (dry pollen): irregular,  infoldings (dry pollen): aperture(s) sunken,  aperture number: 1,  aperture type: -,  aperture condition: ulcerate,  aperture peculiarities: aperture membrane smooth

Ornamentation and Structure

LMornamentation LM: reticulate,  nexine: -,  sexine: -,  SEMornamentation SEM: reticulate,  TEMtectum: semitectate,  infratectum: -,  foot layer: -,  endexine: -,  intine: -,  wall peculiarities: -

Miscellaneous

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

Annotations

The tetrads are not strictly tetrahedric, also planar. The aperture are not exactly at the distal pole.

The tetrads are united to pollinaria which disintegrate.
