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): 21-25 µm,  shortest polar axis in equatorial view (LM): -,  longest polar axis in equatorial view (LM): -,  shortest diameter in equatorial or polar view (LM): 21-25 µm,  longest diameter in equatorial or polar view (LM): 21-25 µm,  pollen class: inaperturate,  polarity: isopolar,  P/E-ratio: -,  shape: spheroidal,  outline in polar view: circular,  dominant orientation (LM): oblique,  P/E-ratio (dry pollen): -,  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

LM  ornamentation LM: verrucate, gemmate, scabrate,  nexine: present,  sexine: present,  SEM  ornamentation SEM: no suitable term,  suprasculpture SEM: -,  TEM  tectum: -,  infratectum: columellate,  foot layer: -,  endexine: compact-continuous,  intine: monolayered,  wall peculiarities: -,  supratectal element: -

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.
