… (those under discussion this morning), microscopy seems to be a critical element.

Despite a lot of genetic study effort put into the Validae (the relative stability of brunnescens, the apparent circumarctic distribution of porphyria, the segregation of lavendula from two genetically distinct look-a-likes, the recognition of multiple taxa within the North American rubescent group, etc.) there is a very large amount of work that needs to be done.

Very best,
