Very nice work. Can you tell me what kind of lens did you use?

I’m with those guys…

Well, well. I agree with the assessments of these photographs. It sure is an eye-catching species. For a world view of sect. Caesareae, I can’t resist pointing to a recent attempt at organizing the taxonomic knowledge. I hope it will prove useful. At the very least, you can see that the European caesarea and its ilk are easily distinguished microscopically from the group represented by jacksonii (which has a very wide distribution and rather high diversity):


Very best,
