How does one differentiate between these two hybrids of P. hirtzii and P. longifolium? P. x roethianum occurs naturally, so does that mean only plants descending from wild populations can be called P. x roethianum? And plants with a P. hirtzii parent and a P. longifolium parent bred in captivity would be P. Rio Mira, as well as all subsequent (F2, F3, etc) generations?
