Phylogeny of Corydalis (Papaveraceae:Fumarioideae) inferred from chloroplast DNA sequences: implications for classification and historical biogeography.
Corydalis is a large genus (465 spp) of mainly N Temperate herbs that is particularly diverse in China (357 spp, 262 endemic). We constructed a molecular phylogeny of 202 species of Corydalis using the cpDNA markers rps16, matK, trnTL, and trnLF. Taxon sampling was broad across subgeneric taxa and geographic areas and included representatives of several outgroups. Our results yielded a phylogeny with many well-supported clades (inferred by bootstrap analysis using RaxML) that largely confirm traditionally recognized taxonomic groups within Corydalis. We are presently using the phylogeny to investigate patterns of heterogeneous diversification in light of morphological trait evolution and historical biogeography.
