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: inaperturate, polarity: isopolar, P/E-ratio: -, shape: spheroidal, outline in polar view: circular, dominant orientation (LM): -, 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: granulate, 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: In almost all anthers, pollen was degraded. In one anther pollen in different stages has been observed: from tetrads to young microspores and degraded pollen . Young microspores with lamellar endexine, mature microspores with compact endexines. Infratectum often absent, if present columellate. Identification of footlayer and tectum not possible.
