Botanical Description

Dialium guianense (Aubl.) Sandwith (Fabaceae, Dialioideae), ironwood, paque or tamarindo de monte, is a large evergreen canopy tree of moist and seasonally dry lowland forests of the Neotropics, ranging from southern Mexico and the Caribbean lowlands of Central America through the Guianas and Amazon basin to Bolivia and southern Brazil. Mature trees reach 25-40 m tall with a long straight cylindrical trunk up to 1 m in diameter, often slightly buttressed at the base, supporting a dense, dark green crown. The bark is grey-brown, smooth to slightly scaly and exudes a reddish sap. Leaves are alternate, imparipinnate, 10-20 cm long, with five to seven alternate, asymmetrically ovate to oblong leaflets 4-9 cm long. Terminal and axillary panicles bear many small fragrant whitish flowers with reduced petals and conspicuous stamens. The fruit is a small subglobose indehiscent pod 1.5-2.5 cm across with a brittle black velvety shell enclosing a sweet brown pulp and one or two flat hard seeds.

Cultural & Historical Context

Traditional American Uses

In southern Mexico, Belize, Guatemala and Honduras the bark of Dialium guianense (locally known as paque, tamarindo de monte or guapaque) is occasionally used in domestic decoctions for diarrhoea, dysentery and as an astringent wash for skin complaints, and the sweetish fruit pulp is eaten and given to convalescents; reported by Maya and Mestizo informants in ethnobotanical surveys of the Yucatán and Petén regions (Arellano-Rodríguez et al., 2003; Comerford, 1996).
