In biology the “cf.” is usually placed in-between the

It’s list of Homotypic Synonym(s) is quite impressive with everything from: Navicula librile Sphinctocystis librilis Frustulia librilis Cymatopleura librile As you can see, and I hope you do more research on it, this diatom has been

For instance, Pediastrum duplex is separated out from other species by having very large and
