Wood Anatomy of the Neotropical Sapotaceae XVII. Gambeya

摘要

Gambeya is an African genus to which Aubreville added Gambeya excelsa (Huber) Aubr., based on the Amazonian Chrysophyllum excelsum Huber. Whether Gambeya is the appropriate taxon for the American species remains to be resolved. Wood specimens indicate that several species occur in the Americas ranging from Southern Mexico to the Peruvian Amazon. The woods of the neotropical Gambeya are an off-white color unique among the predominant browns and red browns so typical of the Sapotaceae. The wood is further distinguished by the radial arrangement of the pores, reticulate parenchyma, lack of silica, and the presence of microcrystals in the wood rays and axial parenchyma. A unique genus of the Sapotaceae. (Author)
