A skeletal world revision of the genus is presented to accompany a family account for Flora Malesiana. 82 species are recognised, of which 74 occur in the Malesiana region. Six species are described as new, one species is raised from infraspecific status, and five species are restored from synonymy. Many names are typified for the first time. Three widespread, or locally abundant hybrids are also included. Full descriptions are given for new (6) or recircumscribed (7) species, and emended descriptions of species are given where necessary (9). Critical notes are given for all the species. Little known and excluded species are discussed. An index to all published species names and an index of exsiccatae is given.

W.J.J.O. De WildeFollowing the introductory sections, a general key, and regional keys, noteworthy observations are given for selected species of Myristica covering the whole distributional area of the genus west of New Guinea. New taxa, i.e. species (14), subspecies (10), and varieties (2) are fully described and annotated. All accepted names are arranged alphabetically, followed by an index.

The genus Parsonsia is revised in the Malesian region. Lyonsia, Helygia, Cudicia, Chaetosus, Delphyodon, and Grisseea are included in synonymy and 27 species are recognised, one of which has 7 varieties. There are 9 new species, 4 new varieties, 2 new combinations and 2 new statuses, one of which is also a new combination.

The genus Canavalia (LeguminosaeñPapilionoideae) is briefly introduced. Comments on several species are given. A key to the Malesian species is presented.

Three genera are recognised, Leptochilus, Microsorum, and Podosorus. Lepisorus probably also belongs here, but is left out because this work started as a precursor for Flora Malesiana, and most Lepisorus species occur outside the Malesian area. The following genera, recognised by Bosman (1991), are reduced: Colysis (to Leptochilus), Neocheiropteris and Phymatosorus (to Microsorum). Many new combinations have been made. Microsorum hainanense is newly described and an evaluation is given of the main characters important for recognising species, viz. the venation and the arrangement of the sori.

The variation within the widespread West Malesian species Cratoxylum arborescens (Vahl) Blume was analyzed and three distinctive variants were found. These are recognized formally as varieties, var. arborescens, var. miquelii King, and var. borneense A.C.Church & P.F.Stevens. A key and full descriptions are given. The characters employed to delimit the three taxa are discussed and the selection of varietal rank is justified.

In the framework of a revision of the genus Dictyota J.V. Lamour. in the Indian Ocean, all specimens from Indonesia present in the herbarium Weber-van Bosse (L) were re-examined. This resulted in a total of 9 species, one species including two different growth forms. Our identifications differ substantially from those of Weber-van Bosse (1913). Specimens recorded as D. apiculata J.Agardh were re-identified as D. crispata J.V. Lamour., which is the correct name for D. bartayresiana sensu Vickers; similarly was D. bartayresiana var. b re-identified as D. cervicornis Kütz., D. fasciola (Roth) J.V. Lamour. as D. ceylanica Kütz. and D. ceylanica Kütz. var. rotundata WeberBosse as D. friabilis Setch. Dictyota pardalis Kütz. considered as a distinct species by Weber-van Bosse (1913: 184), is treated as a synonym of D. cervicornis. In addition a new combination is made for a growth form of the latter, characterized by recurved branchlets: D. cervicornis f. pseudohamata (Cribb) De Clerck & Coppejans. Dictyota beccariana Zanardini is considered to be a synonym of D. ciliolata Sond. ex Kütz. A single specimen, previously assigned to D. beccariana, belongs to D. dumosa Børgesen. This is the first report of D. dumosa for the Malayan region. A new species, D. canaliculata De Clerck & Coppejans is described from preserved material, not reported in Weber-van Bosse (1913).

Omalanthus is revised for Malesia and the Solomon Islands. For this region, 13 species without subspecific taxa are accepted, namely O. arfakiensis, O. caloneurus, O. fastuosus, O. giganteus, O. grandifolius, O. longistylus, O. macradenius, O. nervosus, O. novoguineensis, O. populifolius, O. populneus, and O. trivalvis, and, as a new species, O. remotus. In addition to established synonyms, 17 species from Malesia are not accepted any more. The diagnostical importance of a peltate or non-peltate leaf base is especially doubted. Although detailed phylogenetic and biogeographical analyses were not made, the value of the established sections of Omalanthus is questioned. An alternative subdivision unites all Malesian taxa into four subgroups, each with a distinct distribution of probably historic causes. The subgroups are distributed in W and C Malesia, the Lesser Sunda Islands, the Philippines and the Bismarck Archipelago, and New Guinea and Australia, respectively. The radiation in montane and subalpine habitats may also have contributed to the actual diversity. In addition, O. gracilis from French Polynesia is proposed to be a synonym of O. stokesii.

As compared with the treatment in the Flora of Java (Backer in Backer & Bakhuizen van den Brink, 1963) with 8 species, a recent review of the genus Trichosanthes in Java resulted in the acceptance of 10 species for this island. Important changes are: the name T. trifolia has to be replaced by a later species name, T. wawrae Cogn.; T. anguina is a variety of T. cucumerina [T. cucumerina L. var. anguina (L.) Haines]; the name T. bracteata as used in the Flora of Java appeared to represent three other different species: T. tricuspidata Lour., T. quinquangulata A.Gray, and T. pubera Blume; and T. sumatrana Cogn., never recorded before, appeared to occur in Java.
