The new generic name Diplosophyllum Doweld is proposed to replace a later homonym, Diplophyllum Velenovský & Viniklář (non Dumortier nec Lehmann). The generic names Cussoniophyllum Doweld gen. nov., Hederago Doweld gen. nov., and Priscophyllum Doweld gen. nov. are validated replacing the invalidly published Cussoniphyllum, Hederophyllum and Grevilleophyllum, respectively. The new combinations Cussoniophyllum partitum (Velen.) Doweld, Diplosophyllum cottae (Ettingsh.) Doweld, D. cretaceum (Velen. & Viniklář) Doweld, D. elongatum (Velen.) Doweld, D. inaequale (Velen.) Doweld, D. primigenium (Saporta) Doweld, Hederago credneriifolia (Velen.) Doweld, H. primordialis (Saporta) Doweld, and Priscophyllum constans (Velen.) Doweld are proposed. The names Diplophyllum cretaceum Velen. & Viniklář, Hymenaea elongata Velen., H. inaequalis Velen., H. primigenia Saporta, Hedera credneriifolia Velen, and Grevillea constans Velen. are lectotypified and Hedera primordialis (Saporta) is neotypified.
