Evolution and Systematics

Evolution

Phylogeny of Oleaceae were assessed by a cladistic analysis of DNA sequences from two noncoding chloroplast loci, the rps16 intron and the trnL-F region (Wallander and Albert, 2000). Results indicated that the Tribe Jasmineae is monophyletic, but Jasminum is paraphyletic with Menodora nested within it, as Kim and Jansen (1993) and Rohwer (1996) have suggested.
