Abstract
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. A group of mainly lowland, South American Randia species is moderate supported (75%). Species from Mexico form a strongly supported (97%) clade, but the Central American and Mexican Randia species are low supported (58%). However the last two groups are well supported together (95%). The molecular delimination is well in line with the size of leaves combined with the texture of exocarp.
