This actual plant was sent to Mark Wilson in Colorado for his opinion on the ID. His email to me follows:



Bryon:

Yes, that is P. discoidea - very nice!!! Please could you preserve a few flowers for me in 70% ethanol (did I remember to say thanks for sending the P. aff. imperialis flowers - if I forgot that too, please accept my belated thanks). At some point I need to write something about distinguishing P. discoidea and P. isthmica and some related new species so flowers would be helpful since I don't grow that species.
