In his landmark "Flora Australiensis", English botanist George Bentham published the first key for the nine described species of "Brachychiton", and relegated them to a section of "Sterculia". Hence the Queensland bottle tree became "Sterculia rupestris". Von Mueller maintained his recognition of "Brachychiton" as a separate genus. German botanist Otto Kuntze challenged the generic name "Sterculia" in 1891, on the grounds that the name "Clompanus" took precedence. He republished the Queensland bottle tree as "Clompanus rupestris". German botanist Karl Moritz Schumann gave it its current binomial name in 1893, which was accepted by Achille Terraciano of the Orto botanico di Palermo and subsequent authorities, and remains current.
