Pollen Description
Shape, Size and Aperture
pollen unit: monad, dispersal unit and peculiarities: monad, size (pollen unit): large (51-100 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: sulcate, polarity: isopolar, P/E-ratio: -, 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): no suitable term, infoldings (dry pollen): aperture(s) sunken, aperture number: 2, aperture type: sulcus, aperture condition: disulcate, sulcate, aperture peculiarities: -
Ornamentation and Structure
LM ornamentation LM: -, nexine: -, sexine: -, SEM ornamentation SEM: microbaculate, echinate, suprasculpture SEM: -, TEM tectum: -, infratectum: -, foot layer: -, endexine: -, intine: -, wall peculiarities: -, supratectal element: -
Miscellaneous
pollen coatings: -, reserves in cytoplasm: -, cell number: -, Ubisch bodies: present
Annotations: the 2 apertures are situated in the equator and parallel to the equator; therefore the aperture condition is disulcate and not dicolpate; shape in hydrated conditiion oblate to spheroidal
