Resumen:
In its current circumscription, the herbaceous tribe Spermacoceae s.l. (Rubiaceae, Rubioideae) unites the former tribes Spermacoceae s. str., Maneltieae, and the Hedyotis-Oldenlandia group. Within Spermacoceae, an(] particularly within the Hedyotis-Oldenlandia group, the generic delimitations tire problematic. Up until now, molecular studies have focused on specific taxonomic problems within the tribe. This study is the first to address phylogenetic relationships within Spermacoceae front a tribal perspective. Sequences of three plastid markers (atpB-rhcL, rps16, and trnL-trnF) were analyzed separately as well as Combined using parsimony and Bayesian approaches. Our results support the expanded tribe Spermacoceae its monophyletic. The former tribe Spermacoceae s. sir. forms it monophyletic clade nested within the Hedyotis-Oldenlandia grcup. Several genera formerly recognized within the Hedyotis-Oldenlandia group are supported as monophyletic (Amphiasma Bremek., Acrytophyllum Willd. ex
