Tabebuia heterophylla (DC.) Britton (Bignoniaceae) is a charismatic neotropical tree species known for its attractive flower sand economically valuable wood. The species is considered to have an extremely wide distribution throughout the Caribbean, where it thrives in a diverse range of habitats, soil conditions, and altitudes (Gentry,1992). In Puerto Rico, where it is very common, the species is found from dry to wet forest habitats, from sea level to high altitudes, and is morphologicaly highly variable (e.g.,leaf size and leaf let number variation). However, it is not known whether the variation is due to phenotypic plasticity or whether there are genetically distinct population sand evolutionary lineage. The purpose of the project is to study the phylogeography and genetic diversity of natural populations of Tabebuia heterophylla through the use of DNA equence and microsatellite data.
