Albizia xerophytica was described from material from dry forest habitats in southern Honduras based on minor differences in leaf and fruit morphology, but we do not consider these to be significantly different from the range of variation that is observed in P. adinocephala and prefer the broader concept of the species as described in Barneby and Grimes (1996 : 218-220). The difference in habitat (i.e., lower rainfall regions) also appears to be minor, as some specimens from wetter sites have been identified as A. xerophytica (see map in Rico Arce et al. 2008 ) while specimens of P. adinocephala have been collected across the full range of drier and wetter sites. Finally, the distribution of A. xerophytica is entirely enclosed by the much wider range of P. adinocephala .
