Wood anatomy of Exostyles venusta (Swartzieae, Papilionoideae, Leguminosae)

Abstract

The genus Exostyles consists of two to three species from Brazil. This paper describes the wood of E. venusta Schott, completing generic coverage of the wood anatomy of the tribe Swartzieae as defined by Cowan (1981). Small twigs from herbarium sheets of E. glabra and E. amazonica (labelled E. venusta) were also examined. Exostyles wood anatomy is compared with that of the other genera in the tribes Swartzieae (Gasson 1996) and Sophoreae (Gasson 1994; Fujii et al. 1994), and is very similar to three closely related genera of Swartzieae, Zollernia, Harleyodendron and Lecointea.
