| Two decades ago the senior author was urged by the West New Guinea Forest Service to name a rather common canopy tree of New Guinea and the Moluccas. Among two dozen collections there was only one in flower, from the island of Ceram. Though the species was certainly new for Malesia, the absence of fruit explained his hesitation to refer it to one of the genera of the Tristania-Xanthostemon-Metrosideros complex to which it clearly belonged. It was finally described as Metrosideros nigroviridis Steen., the specific epithet alluding to the sepia-coloured twigs and conspicuously green-drying leaves. Finally, about 1960 a fruiting specimen collected by Chr. Versteegh came to hand (BW 4702) which showed by its indehiscent nature and fleshy pericarp that it could... |

| Periomphale Baill. (incl. Pachydiscus Gilg & Schltr. and Memecylanthus Gilg & Schltr.) from New Caledonia is reduced to Wittsteinia F.v.M. from New South Wales. This genus occurs also in New Guinea. Three transfers are made. A new monotypic genus of the group Crispiloba is described from Queensland, based on Randia disperma S. Moore. A general discussion is held on the features of the group and the affinities within it. It has become clear that it has no alliance to the Caprifoliaceae but must be regarded as allied to Saxifragaceae sensu lato, either as a distinct family or as a subfamily. A key is given to the three genera: Alseuosmia from “New Zealand, Wittsteinia from New South Wales, New Caledonia and New Guinea, and Crispiloba from Queensland. |

| In our revision of Caprifoliaceae in Fl. Mal. I, 4 (1951) 175 seq. we omitted to mention Weigelia fallax described by Miquel from Lembang, West Java, collected by Korthals. The specimen was concealed among cultivated specimens and turned up recently. There is no doubt that this specimen is derived from an ornamental in the Javanese hills. We have sent this material to Prof. Hara who found it conspecific with Weigela coraeensis Thunb. It is often cultivated in Japan, especially as a hedge plant. |

| Blume, C. L, Bijdragen tot de kennis van de Flora van Nederlandsch Indië. Reprint of part 4 ( 1850). Dr M. A. DONK draws attention to the fact that part 4 of BLUME’ s Bijdragen was reprinted in 1850, at Batavia. The printers were VAN LANGE & Co, not the Landsdrukkerij this time. A copy of this second edition is in the Bibliotheca at Bogor. The letterprint is different from that of the original and the paper is of inferior quality. The numbering of the pages is kept as much as possible in agreement with the original edition. At Bogor there is an other copy of the Bijdragen in which part 4 is in MS,; this indicates that at some time no stock was available of the original edition. |

| 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... |

| This remarkable rheophytic fern which is often massed in cracks of rocks in or near cascades in streams subject to sudden overflows had a peculiar distribution, being rather common in such habitats in Sumatra, Malaya, and Borneo, but also found on Mt. Salhutu in Ambon (Moluccas). It has recently also turned up in East New Guinea. EAST NEW GUINEA. Territory of New Guinea: West Sepik Dist., Telefomin Subdist., in Prospect Creek near Frieda R., 4°42' S, 14i°48' E, at 450 m, on large rocks in streambed (PH Creek), NGF 42540 E. E. Henty & D.

| In 19491 pointed attention to the fact that the annonaceous generic name Oxymitra (Bl.) Hook. f. & Th., Fl. Ind. (1855) 145, is a later homonym of the ricciaceous genus Oxymitra Bischoff ex Lindenb., Syn. Hepat. Eur. (1829) 124. Cf. Bull. Bot. Gard. Buitenzorg ser. III, 17: 458. As the name of the hepatic genus is still in use it seemed to me impossible to suppress it and consequently I proposed a new generic name for the annonaceous genus, viz. Friesodielsia, without making any new combinations under that name. |

| The enumeration of about 760 species and 140 varieties and forms of marine algae growing along the eastern coasts of the tropical and subtropical parts of America, and belonging to the Phacophyceae, Chlorophyceae, Xanthophyceae, Cryptophyceae, Chrysophyceae, and Rhodophyceae, is preceded by an historical review of collecting and knowledge of those algae. One new family, Wurdemanniaceae, eight new species of the genera Caulerpa, Dictyota, Dictyopteris, Padina (by Thivy), Cryptonemia and Ceramium, and four new varieties belonging to the genera Dictyota, Galaxaura, Rhodymenia, and Herposiphonia, have been described. Several formae are only marked as such, but not given a name. A number of new combinations are found all through the systematical part of the... |

| This volume covers entries from the letters Ph—Re of this Cyclopaedia, which next to entries on plants (457 in all) contains also entries on minerals and animal products. Plants are arranged alphabetically under generic names. The impression is that plants are more lavishly treated in detail than the two other categories which together cover only 28 pp. The other 7 volumes also contain mainly botanical information; 90 % of the total entries being botanical. The series is essentially a modem treatment of George Watt’s ‘A Dictionary of the Economic Products of India’, 1889—1893, 6 vols.; a very large amount of information from an enormous literature is digested in this modern account. General information is given on a fairly large number of genera which are... |

| The taxonomic position and rank of the only genus Sphenostemon has a chequered history. In the course of time it has, under various names, been attributed to the Aquifoliaceae (by BAILLON, as Sphenostemon, 1875), to the Icacinaceae (as a species of Phlebocalymna, by F. VON MUELLER, 1875), to the Guttiferae (as Nouhuysia, by LAUTERBACH, 1912), and to the Trimeniaceae (by GIBBS, as Idenburgia, 1917). BAILEY & SWAMY (1953) and BAILEY (1956) examined the anatomy and concluded that the genus could not belong to either Guttiferae or Trimeniaceae cq. Monimiaceae, but they gave no clear alternative. When I summarised the complete generic synonymy (1955), I found it likely to retain Sphenostemon in Aquifoliaceae. |
