| Trees or shrubs. Leaves spiral or in pseudo-whorls, sometimes subopposite, generally coriaceous, simple or pinnatisect, often dimorphous, entire or toothed, sometimes spiny. Stipules 0. Inflorescences mostly axillary or rami- or cauliflorous, or terminal. Bracts (potentially) present but mostly small, often minute and very early caducous or barely visible, sometimes large, accrescent and woody (in cone-like spikes). Bracteoles 0-2, small. Flowers in racemes, umbels or spikes, the latter sometimes cone-like, not rarely inserted in twos; pedicels of the pairs sometimes connate to various degree. Flowers choripetalous (though segments sometimes remain connate or partly so, sometimes with a spathaceous corolla), actinomorphous, sometimes zygomorphous (by... |

| Trees or erect, rarely scandent shrubs, sometimes hemi-, rarely autoparasitic. Leaves spirally arranged, rarely distichous, simple, entire, often with parchment-like and/or finely tuberculate surfaces, mostly penni-, rarely pli-nerved, petioled, exstipulate, not rarely of a greyish-yellowish-olivaceous colour and dull, especially in the dry state. Inflorescences axillary, rarely on old wood, short racemes and panicles, or elongate spikes, often fascicles or glomerules, these rarely reduced to a solitary flower. Flowers generally bisexual, rarely unisexual (monoecious or andro-dioecious), generally actinomorphic, cyclic, 3—7- merous, rarely heterostylous. Calyx small in anthesis, often very shortly 3—7- lobed, -dentate, or -crenulate, the cup-like base free... |

| Trees or shrubs, evergreen (Mal. spp.); leaf-scars large. Leaves crowded towards the end of the shoots, spiral, simple, exstipulate, serrate with glandular teeth, often with an apical gland, more rarely entire; nerves a little decurrent along the midrib, both midrib and nerves ± impressed above, ± prominent beneath. Indumentum of branchlets, leaves and inflorescences consisting of simple, and/or long, fascicled and ± patent, and/or minor, ± depressed stellate hairs. Flowers bisexual, regular, 5(-6)-merous. Inflorescences sometimes simple solitary terminal racemes, but mostly consisting of a terminal raceme and several lower approximate racemes, each of the latter from the axil of a ± reduced or caducous leaf, thus forming together a panicle-, fascicle- or... |

| The amount of both living and herbarium material of Ericaceae, which has become accessible to the author in and from Malaysia since his various precursory papers on the family have been published, are the reason for this supplement. In Borneo, collecting in the last years has increased considerably in its northern part. In Sarawak, J. A. R. Anderson and E. F. W. Brunig collected a large number of Ericaceae on various mountains, partly not yet previously visited both within the ‘kerangas’ and the mossy forest. In N. Borneo it was Mrs Sheila Collenette who in 1960 climbed Mt Trus Madi, with c. 2620 m altitude the highest peak there next to Mt Kinabalu, and found on it a new species of Rhododendron besides other species, described from and thought to be... |

| My revisional work in the Flacourtiaceae confronted me with the genus Homaliopsis Sp. Moore, J. Bot. 58 (1920) 187, from Madagascar, based on a Forbes collection without locality, and never recollected. The genus was placed in the Flacourtiaceae by Sp. Moore himself, and, with reservation, included in its tribe Homalieae by Gilg in E.-P., Nat. Pflfam. 2nd ed., 21 (1925) 424; it has remained there in Perrier's revision of the family for Madagascar (Fl. Madag. Fam. 140, 1946, 119) and still in Hutchinson, Gen. Fl. Pl. 2 (1967) 217. Already the study of the original description which speaks of leaves with pellucid dots and a simple (not partite) style raises doubts whether Homaliopsis really belongs to the Homalieae, or even, by the mention of stamens... |

Tomes 1-10, 1910-1922”, several publication dates of the parts of French works could be stated with more certainty.

| In the present work details are given in the first place for the Malesian Olacaceae, representing the basis of my forthcoming treatment of the family in ‘Flora Malesiana’, in which full descriptions of the Malesian genera and species will be given. As the Olacaceae of Malesia are connected with those of South and Southeast Asia on the one, and those of Australia and the Pacific on the other side, it has been necessary to study the respective materials too. A part of the Malesian genera is represented also in Africa inch Madagascar, and even in Central and South America; the appertaining species have been studied but are not mentioned in this paper. A critical elaboration of the family for Africa and America is urgently needed, but will, as far as can be... |

| Foxworthy and Symington published revisions of the dipterocarp family for the Philippines (11 genera, 52 species) and Malaya (14 genera, 168 species) in 1938 and 1943 respectively. From 1926 till 1961 van Slooten published revisions of several genera for Indonesia, but knowledge of the largest genera, Shorea and Hopea, and of the island with the greatest number of species, Borneo, remained defective. Plans were developed by the Forestry Departments of Sarawak, Brunei, and Sabah, to fill the gap in a coordinated effort, of which this book is the first substantial result. A first precursory paper with new species appeared in Gard. Bull. Sing. 19 (1962) 253—319, a second, with taxonomic and nomenclatural discussion in vol. 20 (1963) 229—284. A Manual for... |

| A taxonomic revision of the Flacourtiaceae of New Caledonia incl. the Loyalty Islands, based mainly on the recently very enriched materials deposited in the Paris Herbarium. This resulted in a total of 53 species, belonging to 4 genera: Casearia, Homalium, Xylosma, and the endemic genus Lasiochlamys; 21 species and 1 variety were described as new and 5 new combinations were made. |

| When revising the Icacinaceae from SE. Asia and Malesia recently, my interest was drawn again to the genus Lophopyxis Hook. f. Designated by its author (1887) tentatively as a member of the Euphorbiaceae, it was rejected from this family by Pax as early as 1890. Engler (1893) transferred Lophopyxis to the Icacinaceae as the type of a new subfamily Lophopyxidoideae. Hallier f. (1910) disputed Engler’s view and retained it in the Euphorbiaceae, from which it was excluded again by Pax & Hoffmann in 1931. A possible place in the Rhamnaceae and Flacourtiaceae was considered and rejected by Gilg in 1918; Bakhuizen van den Brink Jr. & van Steenis (1966) likewise rejected the former, though its alliance with the Rhamnaceae was firmly expressed by Airy Shaw... |

| Since the beginning of the printing of the author’s revision of ’The Genus Rhododendron in Malaysia’ in July 1959 (published in Reinwardtia 5, 2 (March 1960) 45-231), recently collected herbarium material especially from Borneo and New Guinea has amounted to such an extent, that a supplement becomes necessary. The numbers refer to those given in the author’s above cited work. |

| Trees, or whether or not climbing shrubs, or lianas. Leaves spirally arranged, rarely opposite, simple, entire or lobed (in Mal. never crenate or serrate), pennior palmatinerved, exstipulate. Inflorescences mostly axillary, sometimes terminal, rarely extra-axillary, or from old wood, in spikes or spike-like racemes, or often in cymes, both spikes and cymes not rarely collected to panicles or heads, very rarely reduced to few-flowered fascicles or to a solitary flower. Flowers bi- or unisexual, in the latter case at least functionally so, i.e. the plants dioecious, actinomorphic, (4-)5(-6)-, by reduction rarely in part 3-merous, cyclic (with sepals or calyx lobes and petals) or rarely spiral (with petals only in Pyrenacantha, or without petals in the ♀... |

| In 1948, W. B. R. Oliver described the new monotypic genus Plectomirtha, collected by G. T. S. Baylis in 1945 from a single tree on a small rocky islet of the Three King’s Islands off New Zealand. He placed it in the Anacardiaceae, a family hitherto absent from New Zealand. This aroused a certain curiosity both from a taxonomic and plantgeographic point of view, because it would be much intriguing if an endemic genus occurred there. This was the reason why Dr C. G. G. J. van Steenis asked Prof. G. T. S. Baylis from the University of Otago, Dunedin, N.Z., for original material to be able to elucidate this case. A fragment of the holotype, consisting of a few flowers and a leaf, conserved in the Auckland Institute and Museum, became available to our... |

| During a recent treatment of the Proteaceae for “Flora Malesiana” it has become evident that a revision of the generic status of all proteaceous taxa reported from S. Asia and Malaysia as well as from the adjacent regions of Micronesia, Melanesia, Polynesia and subtropical-tropical Australia had to be made to reach a satisfactory correlation of the genera and species concerned as a basis for the discussion of phytogeographical relations both within and outside the proper Malaysian area. During this work it appeared necessary to transfer some species to other genera. A revision of the genus Helicia showed that a group of species had to be segregated as a distinct new genus Heliciopsis. My studies are based on herbarium specimens borrowed from the following... |

| An exhaustive Flora of Delhi, compiled by J. K. Maheshwari, was published by C.S.I.R. in 1963 (for a review see Blumea 13, 1965, p. 174). During the compilation of that flora, 278 line-drawings, illustrating the habits and chief features of the plants found in Delhi, were prepared; they form a welcome addition. In general, the drawings are of a good quality and will be a help to all interested in the determination of Delhi plants. |
