Included here is picture of what I consider one of the most beautiful of all silicoflagellates – and that is saying
something – Corbisema geometrica. This one was found this morning. The geometrica group is quite diverse, now split into several species. There is an almost round basal ring and three struts that rather than meet at a point support a plate. My heart quickens a little every time I see one.
Am back to counting slides in the Horton River section of north Canada, while making taxonomic notes for the systematics section of the resulting paper. I am in a sectio nwith few surprises, perhaps some 8 taxa altogether. My main interest as I do my counts is developing a better understanding of this geometrica group.
