| A revision of the Malesian species in the genus Cleidion is presented. Cleidion javanicum is shown to be the correct name for the widespread type species (instead of the name C. spiciflorum). A new species, C. luziae, resembling C. javanicum, is described from the Moluccas, New Guinea and the Solomon Islands. In addition, C. salomonis is synonymised with C. papuanum and C. lanceolatum is treated as a variety of C. ramosii. In total 7 Malesian Cleidion species are recognized. Cleidion megistophyllum from the Philippines cannot reliably be confirmed to belong to the genus due to lack of information and specimens and is treated as a doubtful species. |

| Mallotus concinnus Airy Shaw, M. havilandii Airy Shaw, M. insularum (Airy Shaw) Slik, and M. miquelianus (Scheff.) Boerl. are very similar in appearance, with opposite leaves of which one large and elliptic, and the other reduced and more or less obcordate. However, a detailed look revealed enough differences to regard them as distinct species. |

| Based on phylogenetic studies with DNA sequence data, the formerly monotypic genus Cordemoya was recently expanded with 16 additional species previously assigned to Mallotus. However, the earliest legitimate generic name available is Hancea, and, therefore, Cordemoya is here reduced to Hancea (20 new combinations are proposed). Subsequently, the subgenus and section Diplochlamys from Asia are renamed to Hancea. Additionally, the genus Adisca is lectotypified with Adisca floribundus (= Mallotus floribundus). |

| The range of diagnostic morphological features in the whole genus Mallotus is reviewed as background to the taxonomic treatment of section Rottleropsis s.l. Special emphasis is given to the indumentum, habit, stipules, leaves, extrafloral nectaries, domatia, inflorescences, flowers, pollen and fruits. Notes on the geographical distribution, ecology, pollinators, fruit and seed dispersal, and uses of the genus are also presented. The section Axenfeldia is reduced to sect. Rottleropsis on account of the absence of suitable morphological characters to distinguish them. A taxonomic revision of 38 species of sect. Rottleropsis s.l. from Malesia, Thailand and Africa is presented, together with regional and synoptical identification keys, distribution maps and... |

| A recent molecular phylogenetic study of Mallotus and related genera showed that three small Asiatic genera are clearly part of a strongly supported main Mallotus clade (Mallotus s.s. clade), rendering the genus paraphyletic. In this paper these genera, Neotrewia, Octospermum and Trewia, are merged with Mallotus. The monotypic Neotrewia and Octospermum were originally described within Mallotus and are now transferred back to it. Trewia was never included in Mallotus; it has two distinct species, for which new combinations within Mallotus are made. A full taxonomic treatment with descriptions, distribution maps and drawings is given for the species transferred, and a new generic description for Mallotus is provided. The morphology of the newly transferred... |
