TRANSFER OF THE GENUS AULANDRA INTO PALAQUIUM (SAPOTACEAE) AND ASSOCIATED NOMENCLATURAL CHANGES

Abstract

Aulandra H.J.Lam (Sapotaceae) has hitherto been treated as a genus of tropical forest trees native to Borneo. To test whether the genus is distinct from Palaquium Blanco, phylogenetic analysis using maximum likelihood was performed on target capture of nuclear data, including all species currently recognised as belonging in Aulandra. The results confirm that Aulandra is nested within Palaquium and should be synonymised with it. One new combination, Palaquium longifolium (H.J.Lam) A.Phang, is made, and the application of the name P. beccarii discussed, resulting in the description of a new species, Palaquium aulandrum A.Phang.
