摘要
Phylogenies of the palm family based on DNA sequences from the trnL - trnF region of the chloroplast genome are presented. Although the region is highly conserved in palms and relatively few sites in the aligned data matrix are parsimony informative, a variety of relationships among members of the family are revealed by the analyses, some of which are congruent with the current classification of the palms, and others which are not. However, consensus trees contain high levels of ambiguosity, partly due to the inadequate numbers of informative characters in the dataset. Additional data are required before well resolved palm phylogenies can be generated.
