Plant Diversity and Evolution

The first comprehensive phylogenetic study of the orchid genus Herminium and its allies is presented, based on seven molecular markers (nuclear internal transcribed spacer, Xdh, chloroplast matK, psaB, psbA-trnH, rbcL and trnL-F) and 37 morphological characters. Phylogenetic analyses indicate that Herminium as currently delimited is paraphyletic and that several genera are deeply nested within it. Based on parsimony analysis of total evidence, the generic circumscription of Herminium is expanded to include Androcorys, Bhutanthera, Frigidorchis and Porolabium. Apomorphic and plesiomorphic character states are identified for various clades recovered in this study. A few species currently wrongly assigned to Peristylus and Platanthera are here included in Herminium. All necessary new combinations are made.
