Etymology
From peri- + colpate.
Meanings
-
(not-comparable, of a pollen grain) Having colpi located in a non-central position.
Erdman would call many of the "colpi" of a pericolpate grain sulculi, as they are not meridional, do not cross the equator, but are more-or-less parallel to it, or colpoids, if otherwise located.
