Is primroseleaf violet a species? If you cross Viola macloskeyi and V. lanceolata, you get plants like this. So one camp believes these are a hybrid. But your plants will be sterile. Wild populations of primroseleaf violets are not always sterile. If you subscribe to the rule that plants of hybrid origin should be sterile, then these wild populations are a species. Michigan Flora includes this as a species, but "with trepidation". Both sterile and fertile populations have been found here.
