Sideroxylon Linnaeus. Subfamily: Sapotoideae. Tribe: Sideroxyleae.
As defined broadly by Pennington (1991), Sideroxylon includes about 75 species, widely distributed in the New World and Old World Tropics (our species are the northern tip of a "tropical iceberg"). Pennington (1991) found that no consistent set of characters could be used to separate Bumelia from other New World genera (such as Mastichodendron and Dipholis), and that the New World segregate genera were also not separable from several Old World genera. Stride, Nylinder, & Swenson (2014) produced a phylogeny that could be compatible with a broad Sideroxylon much like the circumscription of Pennington (1991) or could also be the basis of a more split generic taxonomy. If they are combined, as here and for now, the Linnaean Sideroxylon has nomenclatural priority over Bumelia.
