Ornamentation and Structure

LMornamentation LM: psilate,  nexine: -,  sexine: -,  SEMornamentation SEM: granulate, perforate,  suprasculpture SEM: -,  TEMtectum: eutectate,  infratectum: columellate,  foot layer: discontinuous,  endexine: absent,  intine: monolayered,  wall peculiarities: -,  supratectal element: -

Miscellaneous

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

Annotations: crystalline inclusions in some vegetative nuclei of the Pollengrains. Colpus border without ornamentation. Change from apertural to interapertural region peculiar smooth.
