Systematics Section Ree, Richard [1], Wray, Brian [2], Lidén, Magnus [3]. Phylogenetic relationships and biogeographic patterns in Corydalis (Papaveraceae:Fumarioideae). Corydalis is an herbaceous angiosperm clade of ca. 465 species of annuals, biennials, and perennials, distributed mainly in the N Hemisphere, but richest in China (262 endemic species), especially in the mountains of the south-west: the Sino-Himalaya, one of the few biodiversity hotspots on Earth outside of the tropics. Monophyly of Corydalis, its three subgenera, and several sections is strongly supported. Preliminary analysis of historical biogeography reveals migration out of Central Asia and rapid diversification in the eastern Himalayan region, possibly associated with uplift of the Tibetan Plateau.
