Pterodon Vogel

Note

The earlier affinities of this group of genera are discussed by Polhill (1981c). The analysis of Pennington et al. (2001) confirms that the three genera of Dipterygeae form a monophyletic group which is sister to elements within Swartzieae sens. lat. and Sophoreae sens. lat. (Fig. 30). The Amazonian genus Monopteryx (treated here in tribe Sophoreae) may belong with this group (Lima, pers. comm.). Two of the three genera in Dipterygeae are essentially Amazonian wet forest in distribution (Dipteryx also occurring in Central America with a single species to drier areas in central Brazil, Bolivia and Paraguay), while Pterodon inhabits the drier areas of east and central Brazil and east Bolivia. Wood anatomy has proved diagnostic, particularly in distinguishing between Dipteryx and Taralea (Gasson, 1999), and this has underpinned the conclusions of Lewis & Gasson (2000). The tribe as treated here comprises c. 22 species.

Habit

Trees

Ecology

Seasonally dry tropical forest, woodland (cerrado) and thorn shrubland (caatinga), often associated with rocky outcrops

Distribution

S America (EC states of Brazil and E Bolivia)

Use

The very hard wood is suitable for items requiring durability; also used for medicine, firewood, fodder, as ornamentals and for reforestation
