Full Name: - Quercus infectoria subsp. veneris

Quercus infectoria subsp. veneris (A. Kern.) Meikle (1985)
Infrageneric Classification
Subgenus Quercus, Section Quercus
Nomenclature Note
Basionym: Q. veneris A. Kern. (1904). Often incorrectly referred to as Q. infectoria subsp. boissieri (Reut.) O. Schwarz (1934), but with the inclusion of Q. veneris A. Kern. (1904) at subspecific rank within this taxon, the name has to be Q. infectoria subsp. veneris due to its priority at that rank being established by Q. lusitanica subsp. veneris (A. Kern.) Holmboe (1914). See ICBN Art 11.4 and its Ex. 15. [Some authors refer to Q. infectoria subsp. boissieri (Reut.) Gürke, but Gürke in K. Richter, Plantae. Europaea 2: 69 (1897) was unclear as to at which rank he applied the epithet, so his combination cannot be taken into account for purposes of priority. See ICBN Art. 35.3.]
Some regard this taxon at species level being tree-like with larger, distinctly petiolate leaves, and large acorns, whereas Q. infectoria subsp. infectoria is shrub-like with small leaves, short petioles and smallish acorns.
