chloroplast DNA sequence%Dioscorea sect. Stenophora%maximum likelihood%maximum parsimony%molecular phylogeny.
Seventeen species, one subspecies and one variety of Dioscorea sect. Stenophora Uline were investigated for their phylogenetic relationships based on a sequence analysis of chloroplast matK and rbcL genes and trnL-F intergenic spacer by maximum parsimony and maximum likelihood methods. The results showed that: (a) sect. Stenophora was a strongly supported monophyletic group; (b) D. rockii, D. membranacea, D. banzhuana, and D. simulans formed a moderately supported monophyletic group, and D. prazeri was weakly supported to be sister to this group; (c) D. althaeoides and D. nipponica ssp. nipponica formed a moderately supported clade, and D. nipponica ssp. rosthornii was not a member of this clade; (d) D. zingiberensis and D. sinoparviflora showed a moderate to strong sister relationship; and (e) D. collettii var. hypoglauca and D. collettii var. collettii were sister to each other, but with only weak support.
