Morphology
Symmetry and Form
Monad, radial_symmetry, isopolar, 3-colpate, syncolpate, ellipsoidal in equatorial_view, (sub)circular (3-ap.) or subquadrangular (4-ap.) (angulaperturate) in polar_view
Dimensions
Polar_Axis = 43-47 µm; Equatorial_Axis = 30-34 µm
Apertures
Three syncolpi, joined at two poles bordered by a thick and projecting margo broader at poles, colpus broadly elliptic in equatorial_view; aperture_membrane faintly granular; costae_colpi absent
Exine
Micro-reticulate (lumina <1.0 µm), tectate, tectum thick, infratectum columellate, exine thickness at the mid-point of the intercolpium ±2.5-3.0 µm
Remark
A stenopalynous genus classifiable under the Planchonia type (see Erdtman, G. 1952)
