Delphinieae Chromosome Database

 An updated on-line database of chromosome data of tribe Delphinieae (Ranunculaceae)

The tribe Delphinieae Warming is a large group within the Ranunculaceae, traditionally including four genera: Aconitum L., Delphinium L., Consolida (DC.) S. F. Gray, and Aconitella Spach. Recent advances in phylogeny proposed a new arrangement of previously recognized groups (Aconitella and Consolida nested within Delphinium, and Staphisagria J. Hill restated as an independent genus, Gymnaconitum (Stapf) Wei Wang & Z. D. Chen separated from Aconitum). More recently, the whole tribe Delphinieae has been confirmed as monophyletic.

The Delphinieae Chromosome Database (DCDB) provides the most complete current available information on published chromosome numbers, ploidy-level estimates and other karyological data of Delphinieae, periodically updated to be useful for general building of cytotaxonomical databases and for specific research ongoing projects of systematics and evolution of Ranunculaceae.
