The phylogenetic relationships among some Randia (Rubiaceae) taxa.

Phylogenetic relationships among some Randia (Rubiaceae, Gardenieae) taxa were estimated based on sequence variation in the nuclear ribosomal internal transcribed spacers (ITS) and rps 16 intron (cpDNA). During the investigation of rpsl6 intron of 9 studied Central American Randia species, two well supported subclades were separated. Analysis of ITS data of 16 Randia species shows 3 major clades.
