Comment:Hybrid between Brachychiton acerifolius F.Muell. & B. populneus (Schott & Endl.) R.Br. subsp. populneus.
Comment:G.P.Guymer, Austral. Syst. Bot. 1: 308 (1989) list the name "Brachychiton ×roseus nothosubsp. roseus", but this autonym is not established as no subspecific taxa had been published within "Brachychiton ×roseus" at the time.
APC Comment:A hybrid between Brachychiton acerifolius and B. populneus subsp. populneus known only from cultivation (see G.P.Guymer, Austral. Syst. Bot. 1(3): 308-309 (1988)).
