Doreen Smith reports:”Vernon (he took the pictures) and I visited the sunny S. slopes of Mt. Burdell today to prepare for my next Sunday’s scheduled Marin CNPS outing. I just hope the weather will be kind to the flowers and to anyone who turns up for the walk. We saw the best display of purple mouse-ears, Mimulus douglasii, I’ve ever seen there – plus 23 other species of natives already in bloom. The genus Camissonia has been split-examples of the new interpretation are the genera given to the two Suncups pictured.”
