Good Question

This is what Joe Ammirati told me. When I get back to Vancouver in a couple of weeks, I could try doing what you suggest as I have sequences from both species in the UBC herbarium. The fluorescence is retained in dried specimens. I suppose the ultimate test would be to sequence them, but you can’t do that in the field.

How do we know that’s the ultimate test?
I’m not doubting it out of hand, but has UV data ever been compared with genetic data from the same specimens?

In my own personal experience…

Mature specimens of C. semisanguineus can look like C. smithii. The ultimate test is to put them under UV light. C. semisanguineus will fluoresce while C. smithii will not.
