- Alete bisaccate grain, corpus circular to elliptical with the longitudinal axis greater than the transverse axis. Corpus exine double-layered and tectate; sculpture infrareticulate. Sacci semi-circular, always smaller than the corpus, infrarugulate and diaphanous; breadth of sacci 1/2 to 2/3 diameter of the corpus. Sacci proximally attached subequatorially and distally pendent; distal saccus bases straight. A sharply delimited, prominent lens-shaped sulcus is present on the distal face of the corpus and extends the full height of the corpus; the greatest width being 1/8 to 1/3 of the corpus diameter.
Dimensions: Equatorial diameter (9 specimens) overall 28-39 um, corpus
20-27 um.
