The apparent disjunction of Sterculia ceramica between SE Asia and Madagascar is noteworthy. The place of publication of S. ceramica is often given as R. Brown in Bennett, Pl. Jav. Rar. 233. 1844, which was published in November 1844 and was thus predated by Brown’s preprint published in June of the same year.
