The scope of the present paper is primarily to give a taxonomical revision of the genus Canarium. Furthermore, attention has been paid to some subjects of a more general nature, mainly regarding morphology and geography, without, however, claiming completeness. The last complete revision of the genus was published by Engler in 1883 (in DC. Mon. Phan. 4, 101—151). Of course this is now for the greater part out of date. The later revisions by the same author in E. & P., Nat. Pfl. Fam. ed. 1, 34, 1896, 238—242, and ed. 2, 19a, 1931, 443—450, are not really monographs; moreover, they lost in value by the introduction of a subdivision which was mainly based upon unessential characters.
