Taxonomy
BUCHANAN (), in his "Description of the tree called, by the Burmese, Launzan", gave a detailed Latin description for the plant and stated: "I believe it will be found to constitute a new genus; but I do not venture to give it a name, till the European botanists have ascertained, whether or not it be reducible to any known genus of plants". Launzan was evaluated two years later by SPRENGEL l.c. who based himself on BUCHANAN'S description and named this tree Buchanania lanzan.
The vernacular name launzan was listed by Index Kewensis in the synonymy of Buchanania. BARKLEY () proposed to conserve the generic name Buchanania over Launzan, but this is clearly unnecessary; cf. .
