A number of S. E. Asian taxa of Acanthaceae are here recognized as belonging to the prevailingly African genus Isoglossa . The reasons for doing so are briefly outlined. The synonymy, as regards S. E. Asian Isoglossa, is worked out, generic as well as specific. The following new combinations are formally made: Isoglossa clemensorum (R. Benoist) comb. nov., I. collina (T. Anderson) comb. nov., I. geoffrayi (R. Benoist) comb. nov., I. glabra (Hand.‐Mazz.) comb. nov., I. inermis (R. Benoist) comb. nov., and I. subcordafa (C. B. Clarke) comb. nov. The distribution is outlined and mapped. I. dichotoma is shown to occur in Africa, where I. lactea , and I. strigosula are sunk into its synonymy.
