RESUMO
Thirty-three species of Clerodendrum s.l. and five outgroup genera were included in a sequence analysis of internal transcribed spacers of the nuclear ribosomal DNA. The results of the cladistic analysis were compared to and combined with cpDNA restriction site data from a previous study. All molecular data identified four major clades within Clerodendrum s.l. and showed the genus to be polyphyletic. Clerodendrum s.s., minus Konocalyx and Cyclonema, is monophyletic and the genus should be restricted to this group. Cyclonema and Konocalyx form a clade distinct from Clerodendrum s.s., which has been recognized as Rotheca Raf.
