Description Of The Tree
Botanical Description
The trees are reported to reach heights of 36 m, with trunk diameters of 35 to 55 cm. They develop well-formed and cylindrical boles that are up to 15 or 20 m long. T. impetiginosa presents medium to small sized buttresses.
Natural Habitat
Tabebuia impetiginosa is a widespread tree found in diverse habitats, from pasturelands to rainforests, developing well in the tropical dry forests. It prefers sandy and humid soils.
Natural Distribution
T. impetiginosa is distributed from the north of Argentina until Mexico.
Non Timber Uses
The pores are filled with greenish yellow deposits of lapachol. The dust may cause dermatitis.
