This species is widespread and variable The binomial has often been ascribed to Kudô & Masamune (Ann. Rep. Taihoku Bot. Gard. 2: 27. 1932.) but they mentioned only var. gerontogea and thus did not validate any new name as they ascribed the variety to a then non-existent binomial. The identity of Cudrania chinensis Loureiro, published simultaneously with Maclura cochinchinensis Loureiro, is uncertain as no type material has been found, but the most likely possibility is that it is a spineless form of this species.
