Phylogeny and reclassification of Aconitum subgenus Lycoctonum (Ranunculaceae).

ABSTRACT: Phylogenetic analyses were performed using multiple nuclear (ITS and ETS) and chloroplast regions (ndhF-trnL, psbA-trnH, psbD-trnT, and trnT-trnL) to test the monophyly of Aconitum subgen. Lycoctonum (Ranunculaceae) and reconstruct the phylogenetic relationships within the subgenus. The subgenus as currently circumscribed is revealed to be polyphyletic. To achieve its monophyly, sect. Galeata and sect. Fletcherum, both being unispecific and each having a unique array of characters (the latter even having the aberrant base chromosome number of x = 6), must be removed from the subgenus. The subgenus Lycoctonum should thus be redefined to include only two sections, the unispecific sect. Alatospermum and the relatively species-rich sect. Lycoctonum. The section Alatospermum, which is both morp
