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: 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.
