| Evergreen shrubs or trees, rarely lianes. Leaves decussate, or rarely in whorls of three, exstipulate, simple, entire or dentate, with spherical oil cells in the lamina, bearing simple or stellate hairs or glabrous. Inflorescence terminal or axillary (when in axils of reduced bracts appearing supra-axillary), sometimes cauliflorous, cymose, paniculate, fasciculate or pleiochasial. Flowers unisexual or bisexual, actinomorphic or very rarely (extra-Mal.) oblique, receptacle usually well developed (perigynous), rarely reduced (hypogynous), ± globose or urceolate to widely campanulate; tepals usually inconspicuous, sometimes larger and petaloid, rarely distinct sepals and petals (extra-Mal.), decussate, radial or spiral. — Male flowers with few to many stamens... |

| The six genera Gastonia, Tetraplasandra, Reynoldsia, Munroidendron, Peekeliopanax, and Indokingia form a natural complex distributed from East Africa to the Marquesas and the Hawaiian Islands. The characters which have been thought useful in distinguishing these genera are re-examined. The distinction between Gastonia and Tetraplasandra is redefined, emphasis being placed on the radiating stigmatic arms in the fruit rather than on pleiomery of the stamens. On this basis Tetraplasandra is confined to the Hawaiian group. The monotypic genera Peekeliopanax and Indokingia are reduced to synonymy under Gastonia, which thus comprises all species of the complex west of Samoa. |

| Thirty-nine species are recognized of which twenty-four are described as new ( K. bullata, K. carrii, K. chimbuensis, K. ferox, K. flagelliformis, K. fragrans, K. fugax, K. hartleyi, K. karengana, K. katikii, K. kostermansii, K. latifolia, K. leachii, K. macrantha, K. nitens, K. novobritanica, K. oblongata, K. rosselensis, K. royenii, K. shungolensis, K. sleumeri, K. streimannii, K. sudestensis, and K. versteeghii) ). One new combination is made: K. oligocarpella (Kaneh. & Hatus.) Philipson, and several species are reduced to synonymy. Thirty-six species occur in New Guinea, all but three of these being endemic to that island group. A key to the species is provided and their geographical ranges are given. |

| A synopsis is given of the genus Osmoxylon, Araliaceae, in Malesia and the Bismarck Archipelago, including also one species of the Solomon Islands. In the introduction arguments are given why the genus Boerlagiodendron is merged with Osmoxylon. In all 41 species are recognized and are keyed out. Of each species the synonymy is given, as well as the distribution and collections examined; sometimes critical notes on affinity and variability are added. Two names of which the types are apparently lost and which could not be satisfactorily placed are added as insufficiently known. Nine new species have been described and 20 new combinations appeared to be necessary. Full descriptions of all species will appear in the Flora Malesiana treatment of Araliaceae to... |

| There has been considerable confusion over the name Verbesina pseudoacmella and V. acmella published by Linnaeus in the Species Plantarum (1753, p. 901). He applied these names to definitions taken from his earlier work, Flora Zeylanica (1748, p. 144, 145, nos. 308 and 309), with only one unimportant alteration. The title page of the Flora Zeylanica shows that the book is intended as an account of Hermann’s plants, and this is confirmed for the two species concerned by the close agreement between the descriptions published and the specimens in Hermann’s Herbarium preserved in the Department of Botany of the British Museum. These two Linnean species must, therefore, be interpreted by reference to Hermann’s specimens, regardless of the fact that figures... |

| Four specimens of an Araliaceous species collected in the Vogelkop Peninsula and a neighbouring area of SW. New Guinea are so distinctive as to require a new genus. The large, simple, oblanceolate leaves clustered at the ends of the branches recall the habit of Meryta, but the flowers do not share the highly distinctive features of that genus: in particular, they are hermaphrodite, the calyx is well-defined, and a distinct articulation occurs below the ovary. The technical floral and fruit characters are not unlike those of Polyscias (e.g. there is an articulation below the flower, the style arms are free, and the endosperm is smooth), but their general facies is unlike that genus, and this, together with the distinctive inflorescence and leaf, makes the... |

| Harmsiopanax is a small structurally isolated genus confined to the Malesian Archipelago. The three species here recognized are uniform both in their vegetative and their reproductive features. It has long been recognized that some of the characters of this genus are anomalous within the Araliaceae and a return to its earlier position within the Umbelliferae would have something in its favour. The monocarpic habit is unknown elsewhere in the Araliaceae, but is not uncommon in the Umbelliferae. The character of the fruit, which splits into two dry mericarps, closely approaches the fruit of the Umbelliferae, and the vascularization of the gynoecium (Philipson, 1970) is also characteristic of that family. However, the structure of the leaf-base, the tree... |

| Trimenia was first described by SEEMANN as a genus related to the Ternstroemiaceae. BENTHAM & HOOKER ƒ. (1880) regarded it as more closely related to the Monimiaceae without definitely placing it there. This was done by PERKINS & GILG (1901) who formed the tribe Trimenieae of that family. GIBBS (1917) created the family Trimeniaceae without stating grounds for the separation. GILG & SCHLECHTER (1923) disagreed, thinking the differences between Trimenia and other Monimiaceae too slight. However, a more complete study by MONEY, BAILEY & SWAMY (1950) firmly established the family which is now generally accepted. The work of ENDRESS & SAMPSON (1983) strengthened this conclusion and demonstrated the isolated position of the family by drawing... |

| The type species of tie genus Polyscias (P. pinnata J. R. & G. Forst.) is closely related to a small number of Pacific and Indo-Malayan species, several of which have long been in cultivation. This group of species have a distinctive facies but can be defined most readily by the elongated sheathing leaf-base. The genus has usually been extended beyond this group to include other pinnate-leaved members of sub-family Schefflereae in which the pedicel is articulated below the flower. There has been uncertainty whether to restrict the genus to species in which the style arms are free or also to include species with connate styles. In his treatment of the New Guinea species, Harms (Bot. Jahrb. 56,1920: 374—414) does include some species with connate styles... |

| Trees, shrubs, lianas, woody epiphytes or (extra-Mai.) more rarely herbs. Branches usually stout with leaves clustered at their ends; armed or unarmed; glabrous or with a tomentum of stellate or simple hairs; buds either covered by the stipular sheaths of leaves or by cataphylls. Leaves spiral or rarely opposite or in whorls; petiole usually clasping the stem; stipules either distinct or united into a ligule or absent (in Osmoxylon the petiole bears ± elaborate crests around its base); lamina digitately compound or pinnate, sometimes to the second or third degree, or simple, when either entire or pinnately or palmately lobed, margin entire or dentate. Inflorescence terminal or more rarely lateral; either simple or compound racemes or spikes, or more... |

| Twelve species are recognized of which five (P. womersleyi, P. brassii, P. hooglandii, P. schoddei. and P. clemensae) are described as new. Nine species are reduced to synonymy (P. warburgii, P. puberula, P. myriantha, P. paniculata, P. parvifolia, P. acuminata, P. habbamensis, P. pulchra and P. dallmannensis). All twelve species occur in New Guinea, only one (P. arfakiana) extending westwards into Sulawesi. P. incana, P. gracilis and P. hypargyrea may also occur in Queensland in addition to the three species already described from Australia. |

| Only two species of Gastonia occur in Malesia, but each has a complex taxonomie history. The species which became known first, G. papuana Miq., is evidently an uncommon plant of coastal and lowland forest, but with a very wide range. It has been collected only once, or at most a few times, from each of many islands of the Malayan Archipelago and once from the mainland of the Peninsula. Most of these collections were made in the nineteenth or early twentieth centuries. Only in western New Guinea has this species been collected in more recent times within our area. The distribution of this species shows several disjunctions, the most striking being that between West Irian and its only known locality in the extreme east of the Solomon Islands. It is... |
