Ornamentation and Structure
LM ornamentation LM: -, nexine: -, sexine: -, SEM ornamentation SEM: perforate, suprasculpture SEM: -, TEM tectum: eutectate, infratectum: -, foot layer: -, endexine: -, intine: -, wall peculiarities: -, supratectal element: -
Miscellaneous
pollen coatings: absent, reserves in cytoplasm: -, cell number: -, Ubisch bodies: present
Annotations: disulcate oder diporate (längliche Poren). Wenn sulci, dann liegen sie atypisch und zwar dort wo colpen sind. Eigentlich könnte man in diesem Fall diporat sagen.
