- Monad, circular–subtriangular amb,
stephanocolp(or)ate, 6 or more colpi, colpi syncolpate, colpi arranged
in pairs (geminicolpate); syncolpus formed by the merging
of 2 colpi that are opposite, not adjacent, to each other. This
arrangement creates a number of syncolpi that is half of the total
number of colpi. The area between two adjacent colpi forms a
pontoperculum. The mesocolpium around a syncolpus can detach
completely (forming a pseudoperculum) or remain attached
by a small exine bridge at the apocolpia. Exine semitectate, thick,
columellae distinct, reticulate, large mesh, lumina rounded, polygonal,
or curvimurate.
