| Plants small, annual or perennial, densely tufted, often of moss-like habit, some species forming cushions. Leaves radical or densely distichous on short, branched stems, narrowly linear, canaliculate, provided with a broadly membranous, sometimes apically auricled, mostly 1-nerved sheath. Scape simple, accrescent, the base surrounded with 1 to 3 sheath-like, hyaline, reduced leaves. Inflorescences terminal, head- or spikelet-like, 2—3-bracteate (in some extra-Mal. genera ~-bracteate); bracts distichous, each enclosing 1 to 11 flowers. Flowers hermaphrodite or unisexual, usually subtended by 1 to 3 hyaline glumes; sometimes a few barren and reduced. Perianth none. Stamens 1 to 2; filament(s) filiform; anther(s) dorsifixed, versatile, oblong or linear, 1-... |

| 1. Germination of Scyphostegia borneensis is epigeal (or phanerocotylar). 2. The chromosome number has been found to be n = 9 and 2n = 18. 3. The somatic chromosomes are almost V-shaped, relatively symmetrical, each having a median or sub-median centromere. 4. Chromosomal information of Scyphostegia gives additional evidence for excluding this genus from the Monimiaceae. |

| 1. A simple technique for acetolysis of small quantities of polliniferous (herbarium) material is described and notes on pollen photomicrography are presented. 2. Pollen grains of Sarawakodendron and six related genera, consisting of twenty-nine mostly Malesian species, have been examined and recorded. 3. The result of pollen study on Kokoona and Lophopetalum agrees with the generic delimitation based on gross morphology. 4. At least four pollen types have been found in the genus Lophopetalum on examination of all the species involved. 5. The pollen of Sarawakodendron shows a great resemblance to that of the related genera Xylonymus and Kokoona. 6. The pollen of Hedraianthera and Brassiantha resembles that of Sarawakodendron, Kokoona, and Xylonymus in... |

| There are only two genera of the Aristolochiaceae, Aristolochia and Thottea, so far known to occur in Malesia. In the course of a revision of this family for the Flora Malesiana, some new species of both genera have been found. Eight new ones of Thottea were published in a precursor on that genus (Blumea 27, 1981, 301-332, f. 1-72). There are four new species of Aristolochia from Borneo and one more new Thottea from Sumatra to be described here. |

| During my trip to Malaysia in 1966, sponsored by the Netherlands Foundation for the Advancement of Tropical Research (WOTRO), for doing field work on Anacardiaceae, a new tree genus was found in Sarawak belonging to the family Celastraceae which I have revised for the Flora Malesiana series I, volume 6. While camping at the Nyabau Forest Reserve, Bintulu, Sarawak, with the field team of the Forest Department, I examined and collected a number of interesting plants. The area is quite near the sea coast and the type of forest is intermediate between kĕrangas (heath forest) and dipterocarpaceous forests. One day, the plant collector Mr Sibat ak Luang guided me to see a flowering tree of Anisophyllea ferruginea Ding Hou ( Rhizophorac.). On the way I picked up... |

| 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... |

| In his Numerical List Wallich inserted four specific epithets in the genus Kurrimia, viz 4334 K. pulcherrima Wall., 4335 K. calophylla Wall., 4336 K. paniculata Wall., and later 7200 K.? macrophylla Wall. The latter one was provided with a question mark; it was a new combination for Itea macrophylla Wall. No generic or specific descriptions were provided, merely the indication that the name Kurrimia was named in honour of Kurrim Khan who had faithfully served the Calcutta Botanic Garden as its curator for four decades. A few years later Walker-Arnott described a genus Bhesa Ham. ex Arn. (Edinb. New Phil. J. 16, 1834, 315) for which he provided a full generic description and brief but clear diagnoses of two species, viz B. moja Ham. and B. paniculata Arn.,... |

| There is a great diversity of opinion regarding the interpretation of the genera and some species in the former Hippocrateaceae. If one reads the comprehensive and detailed revision of the New World Hippocrateaceae by A. C. Smith (Brittonia 3, 1940, 341—555), one may have an impression of it. For example, A. C. Smith in his monotypic genus Hemiangium, under H. excelsum, has united species which were recognized as belonging to three different genera by Miers; he has also limited Hippocratea L. to a single species, H. volubilis L., and placed more than 40 names of species and varieties in the synonymy of it. A detailed review of the history and generic delimitation of the family Hippocrateaceae has already ably been summarized and discussed by A. C. Smith in... |

| Among the unnamed material of Celastraceae received from the Paris Herbarium for determination, there was one flowering specimen of Microtropis, collected by M. Schmid from South Vietnam in 1953. It was difficult to name it to species with certainty. In order to clarify its identity, I received kind help from the Herbaria of Kew and Paris by sending me specimens on loan for comparison. After studying the specimens concerned, I have concluded that the collection of Schmid represents an undescribed species. In the course of studying the new species and annotating the material of Celastraceae received recently by the Rijksherbarium, Leiden, I examined also other specimens of extra-Malesian Microtropis. Together with the description of the new species, the... |

| Trees, erect or scandent shrubs, or climbers, very rarely epiphytic shrubs; usually with acrid, often turpentine smelling sap becoming black when exposed to the air. Buttresses sometimes present. Stipules absent. Leaves often crowded at the (thickened) end of twigs, spiral or alternate (only opposite or decussate in Bouea), sometimes subverticillate; simple, uni- or tri-foliolate, imparipinnate, rarely paripinnate (Euroschinus) (bipinnate in extra-Mal. Spondias sp.); margin entire (rarely crenate-dentate in Rhus spp.); petioled (petiole often thickened at the basal part), rarely subsessile or sessile. Inflorescences terminal and/or axillary, rarely cauliflorous, paniculiform (panicles or thyrses), sometimes racemose or spiciform, rarely flowers solitary;... |

| The family Hippocrateaceae was established by A. L. DE JUSSIEU (Ann. Mus. Hist. Nat. Paris 18, 1811, 486, as Hippocraticeae) and three years later R. BROWN created the family Celastraceae (in Flinders, Voy. Terra Austr. 2, 1814, 554, as Celastrineae). BROWN was well aware that his new ‘order’ (family in our sense) closely approached Hippocrateaceae and hinted at the Possibility that they might be fused later. This was indeed effected by HOOKER f. (in B. & H. Gen. P1. 1, 1862, 358), who reduced Hippocrateaceae to a tribe of the Celastraceae. Still up till the present there has been no unanimity of opinion on this question. Disagreement with HOOKER’S vision started with MIERS (Trans. Linn. Soc. 38, 1873, 319-330) in his elaboration of the South American... |

| Ten new species have been proposed in the following genera: Gluta (5), Swintonia (1), and Melanochyla to- Seventeen new combinations have been made in the following genera: Gluta (11), Melanochyla (3), Semecarpus (1), Drimycarpus (1), and Nothopegia (1). Abaxial epidermal papillae of leaves occur in seven genera. Their patterns (as observed under low magnification), which can be used sometimes as diagnostic characters, are grouped and representative species listed. The genus Drimycarpus is newly recorded for the flora of Malesia. The generic delimitation of Gluta and Melanorrhoea has been reviewed, and reasons are given why the latter is merged with the former. Coalescent cotyledons, recorded until now only for Gluta renghas, have been found occurring also... |

| I have been asked by friends concerning the photographic equipment, especially for close-ups, which I took with me, my experience of photography in the tropics and the results. One can learn useful information from the concise pamphlet ”Photography in the Tropics” (Kodak Data Booklet GN-5). The present notes on practicing actual picture-taking in the humid and hot climate could serve as a reference to fellow botanists who for the first time make a trip to the tropics and would like to take photographs, especially close-ups. For travelling abroad, I have tried to keep my photographic equipment as simple and light as possible. Since I used Exakta as my work-horse, I took two bodies of it with interchangeable viewers. The lenses consist of one each of 35 mm,... |

| The flowering specimens of Glyptopetalum are very difficult to separate from those of Euonymus except by examining the number of ovules in each cell of the ovary. The ovules are mostly 2, rarely 3—12, per cell in Euonymus and there is only one in Glyptopetalum. However, the genus Glyptopetalum can be easily distinguished from Euonymus, or recognized, by the characteristic persistent columella of the fruit and the branched raphe of the seed (cf. also Fl. Mai. 1, 5, 1963, 256 and fig. 711). In preparing the Celastraceae for the Flora Malesiana, two additional extra-Malaysian species of Glyptopetalum have been found: a new one from Thailand and a new combination for the flora of China. The range of distribution of this genus is now extending to southwestern... |

| The publication of the supplement 1 of the well known and essential reference work of “A Bibliography of Eastern Asiatic Botany” is very welcome. It is a continuation of the original work, which closed with 1936, and extends through 1958. It covers the botanical literature on eastern Asia, as indicated by the title, which comprises China, Japan, Korea, Ryukyu, Mongolia and Soviet eastern Asia, as well as the major published papers appertaining to adjacent areas. It has been prepared on essentially the same pattern as the original volume while the subject index has been treated perhaps in a more thorough manner. The volume contains over 11,000 extensively and carefully annotated entries occupying 414 pages. The work is in English but the titles, papers and... |

| Through the efforts of Dr T. C. Whitmore and Mr G. F. C. Dennis large collections of trees from the Solomons have been accumulated in the past six years. Among them are some interesting collections of the genus Crossostylis, a truly oceanic-Pacific genus, ranging from the Tuamotos westwards as far as and including the Solomon Is. and New Caledonia. A map of its distribution has been given in ‘Pacific Plant Areas’ vol. I, map 23. Whitmore in his ‘Guide to the Forests of the British Solomon Islands’ 1966, p. 174, listed only C. cominsii Hemsl. from the Santa Cruz group. There appears, however, to be a second, undescribed species from the Solomons proper. |

| The generic delimitation of Thottea and Apama has been reviewed. Arguments are given for treating them as one genus, under the name of Thottea. Techniques used for clearing the leaves and for preparing reproductions of the venation have been described. There are two leaf venation patterns, i.e. pinnate and acrodromous, with intermediate forms showing gradual variation. The arrangement of stamens, chief character used for generic distinction, up until now known as occurring in one series (Apama) or two (Thottea), has now also been found existing in three or four series. One new type of seeds in this group has been found, which is rather smooth, flat and longitudinally curved. It resembles that of Saruma and some species of Aristolochia. Scanning... |
