I have 3 populations of Utrics that really do look alike. One came to me as U. calcyfida and one as U. tricolor. The third lost its ID sometime during the winter, but looks like the other two. What I want to do is send a pinch to someone who knows thier Utrics and provide a positive ID. A flower from the one called U. tricolor, with light purple / white / yellow coloration is dubious. Can anybody help me out?
