Monad, radial_symmetry, isopolar, 3-colporate and 3-pseudocolpate (“heterocolpate”), elliptic ( E > P ) to spheroidal in equatorial_view, 6-lobed in polar_view

Dimensions

Polar_Axis = 33-34 µm; Equatorial_Axis = 24-32 µm

Apertures

Three colpora, alternated with three pseudocolpi, both colpus and pseudocolpus elliptic and long colpus, apex acute, distance between the adjacent colpal apices 5.0-6.0 µm, margo undifferentiated, colpal and pseudocolpal membrane psilate, costae_colpi present; Os: bow-shaped, constricted medially, lateral ends curved, lalongate, oral_costae absent(?)

Exine
