Fumariaceae is the botanical name for a family of flowering plants. Such a family has been recognized by a fair number of taxonomists: it is sometimes called the "Fumitory family". The family includes some popular garden plants, such as
The APG II system, of 2003 (unchanged from the APG system, of 1998), does not recognize this family, not as such. However, it does allow it to be segregated from the family Papaveraceae, as an optional segregate. APG II, in as far as it accepts this family, places it in the order Ranunculales, in the clade eudicots. They distinguished 15 genera: Adlumia, Capnoides, Ceratocapnos, Corydalis, Cryptocapnos, Cysticapnos, Dactylicapnos, Dicentra, Discocapnos, Fumaria, Platycapnos, Pseudofumaria, Rupicapnos, Sarcocapnos, and Trigonocapnos
In this circumscription it includes the plants that sometimes have been treated as family Hypecoaceae and thus consists of a dozen-and-a-half genera, with several hundred species, from the Northern Hemisphere and South Africa.
