aStamens are heteromorphic and make the androecium zygomorphic; the corolla is zygomorphic, but much less so than either S. vespertilio subspecies. bPercentage in long anther. cSize (diameter in mm) from Bramwell and Bramwell (1990), except for SVD which is our data. dAll counts from field-collected fruits.
