Papaveraceae or the poppy family, is cosmopolitan in temperate and sub-tropical climates. It consists of 25-30 and ~200 species, most of which are located in the Northern Hemisphere. Plants are hermaphroditic. Members are marked by a milky latex, which could range from white, to yellow, to red. The APG II system classified the families Fumariaceae and Pteridophyllaceae loosely within the Papaveraceae. Genera such as Papaver, Dendromecon, Meconopsis, Eschscholzia, and Platystemmon are members of this family. We feature the genus Sanguinaria with a species pictured below as a geophyte on the wiki.
