Quercus petraea subsp. polycarpa (Schur) Soó

In 1851, Schur mentions the name Q. polycarpa, without a description, on page 170 of Verhandlungen und Mitteilungen des Siebenbürgischen Vereins für Naturwissenschaften zu Hermannstadt. On page 174, Fuss reports on a previous lecture by Schur that included a description of Q. polycarpa as a nova sp. Soó (1943) is the first to have used the rank of subspecies for this taxon under Q. petraea (Matt.) Liebl. as “c.n.”. He repeats this view in a key for oaks in Jávorka & Soó (1951), page 822.
