Revision of the Sapotaceae of the Malaysian area in a wider sense. VII. Planchonella Pierre

This study includes the whole genus Planchonella, contrary to some other publications in this series, which refer only to species found in the area covered by the Flora Malesiana. This seemed desirable both on account of the fact that only a small number of species is found outside that area, and of the doubted generic status of Planchonella versus Pouteria sensu Baehni. Our conclusion is that Pouteria and Planchonella represent two separate genera. Pouteria has its main centre of development in South America, Planchonella in New Guinea, Australia and New Caledonia. The last-named arc has thus so far rather been underestimated as a centre of speciation in Planchonella.
