Pollen Description

Shape, Size and Aperture

pollen unit: monad,  dispersal unit and peculiarities: monad,  size (pollen unit): medium-sized (26-50 µm),  pollen class: inaperturate,  polarity: isopolar,  shape: spheroidal,  outline in polar view: circular,  shape (dry pollen): irregular,  outline in polar view (dry pollen): irregular,  infoldings (dry pollen): irregularly infolded,  aperture number: none,  aperture type: no aperture,  aperture condition: inaperturate,  aperture peculiarities: -

Ornamentation and Structure

LMornamentation LM: granulate,  nexine: present,  sexine: present,  SEMornamentation SEM: no suitable term,  TEMtectum: -,  infratectum: columellate,  foot layer: -,  endexine: compact-continuous,  intine: monolayered,  wall peculiarities: -

Miscellaneous

pollen coatings: absent,  reserves in cytoplasm: lipids,  cell number: 2-celled,  Ubisch bodies: present

Annotations

Young microspores with lamellar endexine, mature pollen with compact endexines. Infratectum often absent, if present columellate. Identification of footlayer and tectum not possible.
