This tree, belonging to the Rutacca, is found in China and Japan, where its bark is largely employed in dyeing and in medicine. It was formerly described by Loureiro as Ptero-carpus flavus, but this error was eventually corrected by P. W. Squire (Pharm. J., (3), 1888, 18, 785), who showed it to be really Evodia glauca, which is synonymous with E. meliaefolia. By qualitative tests, Martin, Tokio (Arch. Pharm., 1878, 13, 337) and Squire (loc. cit.) suspected the presence of berberine, and this colouring matter was subsequently isolated by Perkin and Hummel (Chem. Soc. Trans., 67, 415).
