Phylogeny of the Southwest Asian Pimpinella and related genera based on nuclear and plastid sequences
Downie et al. (2010) provided a general phylogenetic framework within the subfamily Apioideae based on the phylogenetic analysis of nrDNA internal transcribed spacer (ITS) sequences. These analyses revealed the evolutionary relationships of many genera and clades of this subfamily more clearly compared to a pre-existing phylogenetic classification for the group based on the methods used by Downie et al. (2001).
