Papaveraceae A.L. de Jussieu. Poppy Family.

Key to Papaveraceae

A family of 23 genera and about 230 species, mainly herbs (some shrubs and small trees), largely north temperate in distribution. APG IV (2016) treated Papaveraceae broadly, to include Fumariaceae and small splinter families Pteridophyllaceae and Hypecoaceae (sister to Fumariaceae+Papaveraceae). Phylogenetically, this is one option, but another option (followed here) results in smaller monophyletic families that are also morphologically easier to characterize and to use as practical tools in teaching and learning. Pteridophyllaceae is sister to Hypecoaceae+Fumariaceae.
