| Miscellaneous | -- Sub-genus Quercus, Section
Quercus, Series Albae; -- Leaves resembling those of Q.montana; -- André Michaux was a French botanist; -- For today's Authors ( in Flora of North America North of Mexico 1998), Q.michauxii and Q.prinus are synonyms, but this is ambiguous because, on one hand, the "true" Q.prinus L. (= Q.montana Willd.) has often been confused with Q.michauxii, and, on other hand, the name " Q.prinus [auct. not L]." has been often applied to Q.michauxii... that's why it is necessary to name Q.prinus L. "Q.montana Willd." in order to avoid any confusion. |
