The first piece of the putative Equisetum x mideanum – see earlier post – that I sent to Heather McHaffie at RBGE last year produced the suggestion that is was probably just Field Horsetail (E. arvense). A second specimen elicited more doubt – both from Heather and from Chris Page.
Today I went to the site and found three fertile shoots of E. arvense.
So, I definitely have that at the site but will something else appear later in the season?
