↑Possibly a synonym of either A. kwangnanense or A. paxii
↑Often treated as a subspecies of A. campbellii: A. c. subsp. flabellatum (Rehder) E.Murray.
↑Whether this or A. barbatum is the proper name of this taxon is subject to contention, though Michaux's original material was a mix of A. saccharum and A. rubrum. It is often treated as a subspecies of A. saccharum: A. s. subsp. floridanum (Chapm.) Desmarais.
↑Now sometimes considered a subspecies of A. pectinatum: A. p. subsp. forrestii (Diels) E.Murray.
↑Now often considered a subspecies of A. sterculiaceum: A. s. subsp. franchetii (Pax) E.Murray.
↑Sometimes considered a subspecies of A. tataricum: A. t. subsp. ginnala (Maxim.) Wesm.
↑Sometimes considered a subspecies of A. opalus: A. o. subsp. hispanicus (Pourret) E.Murray)
↑Sometimes treated as a subspecies of A. saccharum: A. s. subsp. grandidentatum (Torr. & Gray) Desmarais.
↑Now often considered a subspecies of A. davidii: A. d. subsp. grosseri (Pax) De Jong.
↑Sometimes treated as a subspecies of A. cissifolium: A. c. subsp. henryi (Pax) E.Murray.
↑The relationship between this species and A. caudatifolium is not entirely clear.
↑Sometimes considered a subspecies of A. pectinatum: A. p. subsp. laxiflorum (Pax) E.Murray.
↑Often treated as a subspecies of A. saccharum: A. s. subsp. leucoderme (Small) Desmarais.
↑Sometimes treated as a subspecies of A. platanoides: A. p. subsp. lobelii (Ten.) Gams, or A. cappadocicum: A. c. subsp. lobelii (Ten.) De Jong.
↑Sometimes considered a subspecies of A. pectinatum: A. p. subsp. maximowiczii (Pax) E.Murray. Not to be confused with A. maximowiczianum Miq.
↑Sometimes considered a subspecies of A. miyabei: A. m. subsp. miaotaiense (P.C.Tsoong) E.Murray.
↑The homonyms A. montanum Garsault and A. montanum Daléchamps ex Lam. are synonyms of A. pseudoplatanus and A. opalus respectively.
↑Often treated as a subspecies of A. saccharum: A. s. subsp. nigrum (Michx.f.) Desmarais.
↑Sometimes treated as a subspecies of A. campbellii: A. c. subsp. oliverianum (Pax) E.Murray
↑Linnaeus apparently intended to apply the name to A. sempervirens, but later reused the name for A. obtusifolium, though this is an invalid homonym. In 1995, the name neotypified to A. sempervirens, ending the confusion (Turland 1995).
↑Also "Fulmoon Maple", which is also used for A.japonicum. This is made more complex by A. japonicum var. microphyllum being a synonym of A. shirasawanum.
↑Often treated as a subspecies of A. campbellii: A. c. subsp. sinense (Rehder) De Jong.
↑Sometimes treated as a subspecies of A. saccharum: A. s. subsp. skutchii (Rehder) E.Murray.
↑Sometimes considered a subspecies of A. heldreichii: A. h. subsp. trautvetteri (Medwed.) E.Murray.
↑Sometimes classified as a subspecies of A. caudatum: A. c. subsp. ukurunduense (Trautvetter & Meyer) E.Murray.
↑Often treated as a subspecies of A. campbellii: A. c. subsp. wilsonii (Rehder) De Jong.
↑van Gelderen (p. 245) concludes this is probably an aberrant A. platanoides closer to cultivar status.
↑The identity of the second parent is uncertain, with these two species cited by different authors.
