Description: Of this series of preparations to the definite publication of the Burseraceae in \xe2\x80\x9cFlora Malesiana\xe2\x80\x9d, the present part is giving an additional note on VI. Garuga and dealing with the genera VII. Triomma, VIII. Dacryodes and IX. Santiria (and a new combination in Protium).\nThe present paper gives only additions to and alterations of Lam\xe2\x80\x99s monograph (H. J. Lam, Bull. Jard. Bot. Buitenz., S\xc3\xa9r. 3, 12, 1932, 281\xe2\x80\x94 561); descriptions, synonyms, litterature, specimens cited, ecological and other notes are only mentioned insofar as they are not given by Lam.

Description: The following new species of Terminalia will be included in the forthcoming account of the Combretaceae for the Flora Malesiana where their respective positions in the key will indicate more clearly their relationship to already described species.\nTerminalia capitulata Exell, sp. nov.

Description: Exbucklandia R. W. Brown ( Bucklandia R. Br. non Pr. ex Sternb., Symingtonia Steen.) In an article on \xe2\x80\x9cAlterations in some fossil and living floras\xe2\x80\x9d (J. Wash. Ac. Sc. 36: 348. Oct. 1946) R. W. Brown proposed the new generic name Exbucklandia for the Hamamelidaceous genus Bucklandia R. Br., non Pr. ex Sternb., while describing a new fossil species from the United States. He also transferred B. populnea to the new genus. Unfortunately I had overlooked this publication when proposing Symingtonia to replace Bucklandia R. Br. (Acta Bot. Neerl. 1: 443\xe2\x80\x94444. 1952). Exbucklandia will have to be accepted for it in future. The Indo-Chinese species B. tonkinensis Lecomte should be referred to as Exbucklandia tonkinensis (Lecomte) Steen. comb. nov. I have to thank Dr E. H. Walker for pointing my attention to R. W. Brown\xe2\x80\x99s paper.

Description: The first result of this survey of the wide genera which have endemic species in New Caledonia is certainly to confirm the impression that there is indeed a noteworthy geographical association between Madagascar and that island, even if it is only a particular aspect of a more general relationship between Madagascar and Australasia as a whole.\nBut the survey gives prominence also to another point, namely the unexpectedly small part that tropical Africa plays in the distribution of the genera reviewed. It almost seems as if there is some factor of exclusion affecting that great region, and there is no indication of any corresponding degree of relation between tropical Africa and New Caledonia such as has been detected between the latter and Madagascar.

Description: In the course of my study on the wood-anatomy of Javan woods (Mikrographie des Holzes der auf Java vorkommenden Baumarten), I examined also many woods from mangrove-trees.\nMangrove has been the subject of much investigation; the community is usually described as xeromorphic. Mangrove woods proved to be different from woods belonging to species growing in other stations even if those species belonged to the same family or even genus. The data may be traced in my \xe2\x80\x9cMikrographie\xe2\x80\x9d but it seems more convenient to review them here.

Description: In January 1949 Professor H. J. Lam, director of the Rijksherbarium, Leyden, on his way to the 7th Pacific Science Congress in New Zealand, spending some time in Fiji, was shown by Mr B. E. V. Parham, Department of Agriculture, Suva, Viti Levu, Fiji Islands, a slender tree, cultivated in the Agricultural Experimental Garden Naduruloulou. The tree was unidentified and of unknown origin. Some flowering material was collected and at our request Mr Parham was good enough to send some ripe fruits in liquid for an investigation I was entrusted with.\nAdditional material was studied from the herbaria at Brisbane, Kew, Leiden, Melbourne and Paris. It is my pleasant duty to tender my best thanks to the directors of these institutes for the loan of this valuable material, among which the type.

Description: Up till now the lower deposits of peat (in Dutch: veen-op-groterediepte = peat at greater depth) have been investigated in the Netherlands mainly in the Western part of the country, viz. in the provinces of Noord-Holland, Zuid-Holland and Zeeland. The analyses have shown that the development of this, now comparatively well known peat layer must have begun either in the second half of the boreal period or else in the beginning of the atlantic one, and that it must have come to an end in the first half of the latter. Among the earlier investigators the botanist Mrs VERNEER-LOUMAN and some geologists had arrived at the conclusion that the sudden transgression of the North sea which made an end to the formation of peat, took place in the boreal period, and hat the whole lower deposit of peat, therefore, was of boreal age (lit. 7). This opinion, however, was sufficiently disproved by FLORSCH\xc3\x9cTZ, and all subsequent analyses have confirmed the view that the peat formation must have stopped early in the atlantic period (lit. 2, 3, 4). The same conclusion was arrived at by GODWIN as a result of his investigations of the lower peat found in SE England (lit. 5, 6) and by several German investigators as a result of their analyses of the lower peat, found in NW Germany.\nOnly one analyses of the lower peat in the province of Friesland, in the Northern part of the Netherlands, has sofar been published. The geologist VAN ANDEL found near Kiesterzijl, at a depth of only 3.50 m a thin layer of peat. He identified it with the lower peat from the W part of the Netherlands which occurs several meters deeper. His two diagrams show a boreal age for the basal layers and an atlantic age for the top ones and they confirm therefore the conclusions,obtained in the W part of the country (lit. 1).
