| Shrubs, trees, or lianas, rarely undershrubs or herbs, with a very strongly developed and layered, fibrous, tough bast (“Seidenbast”, silky fibres). Leaves opposite or decussate, spiral or alternate, very rarely some ternate, simple, entire, exstipulate, articulated at the base, glandular-punctate in Gonystyloideae. Inflorescences terminal, axillary or extra-axillary, or on internodes, sometimes on brachyblasts, simple or rarely branched, sessile or peduncled, racemose, umbelliform, spicate, capitate, or fascicled, obviously basically racemose; flowers rarely solitary, sometimes cauliflorous and condensed into glomerules, bracteate (bracts sometimes forming an involucre) or ebracteate. Flowers bisexual (rarely unisexual by abortion and polygamodioecious or... |

| 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... |

| 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... |

| 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.,... |

| The species of the Atlantic Rhizophora have formerly been considered as belonging to one species, R. mangle L. In 1818 G. F. W. Meyer (11) described a second species, R. racemosa, from British Guiana. On working up the Rhizophoras of British Guiana Leechman (10) added a third species, R. harrisonii in 1908, and distinguished all these three species. Through the works of Salvoza (13), Savory (14), Keay (9), Stearn (15), and Jonker (8), it has become clear that these three species occur on the West African and East American shores as well as in some Caribbean islands. In the Old World, from the coast of East Africa to Malaysia, there are also three (other) distinct species as distinguished by many authors and by myself (7). |

| 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... |

| 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... |

| 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.

| 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... |

| 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. |

| One new species of Aristolochia, A. singalangensis, from Sumatra is described here. This is the only Malesian species to have the fruit dehiscing from the apex towards the base. Remarks are given for some Asiatic and Malesian species, all belonging to Aristolochia except one to Thottea, on their taxonomy, nomenclature, typification, characteristics for identification, relationship, distribution, etc. The phenomena and significance of aristolochiaceous plants-butterflies relationship have been discussed. Germinated pollen grains have been found in dehisced anthers of open flowers in both Aristolochia and Thottea. Pollination of the Aristolochiaceae has been concisely reviewed. |

| 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... |

| Evergreen trees or shrubs, mangrove species with various remarkable root formations. Branching (in the mangrove genera) mostly sympodial; branchlets swollen at the nodes, solid and pithy, hollow in Crossostylis, Gynotroches, and Pellacalyx. Innovation continuous, but flushwise in Anisophyllea. Leaves decussate and stipulate, rarely alternate and exstipulate ( Anisophyllea and Combretocarpus), usually isomorphic, rarely dimorphic ( Anisophyllea spp.), gland-like cork warts sometimes occurring as small black spots on the lower surface; young leaves involute or convolute. Nervation generally pinnate, more rarely curvinerved and with 1-2 intramarginal veins ( Anisophyllea). Stipules conspicuous, interpetiolar, caducous, opposite, except in Pellacalyx... |

| 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. |

| 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... |
