Cysticapnos is a small genus of flowering plants in the family Papaveraceae (order Ranunculales, class Magnoliopsida), first published by Philip Miller in 1754 in the Gardeners Dictionary Abridged (4th edition). It is native to southern Africa, with occurrence records spanning South Africa's Cape Provinces, Free State, KwaZulu-Natal, and Northern Provinces, together with Lesotho and Namibia.
The genus comprises a small number of species, including Cysticapnos cracca, Cysticapnos pruinosa, and the type species Cysticapnos vesicaria — the last of which is the species recorded in Ploi's database. In English the genus is known by the common names "Wild Fumarias" and "Threerib Fumarias," and in Afrikaans as "Klappers," names it shares with its relatives in the broader fumitory group.
Taxonomically, Cysticapnos sits within Papaveraceae alongside other fumitory-type genera, and the name Phacocapnos Bernh. is recorded as a synonym, reflecting a history of reclassification among these South African fumitories before they were consolidated under Cysticapnos.
Distribution
Cysticapnos is native to southern Africa. GBIF distribution records place it in South Africa's Cape Provinces, Free State, KwaZulu-Natal, and Northern Provinces, as well as Lesotho and Namibia, matching Wikipedia's description of the genus's native range as "Southern Africa."
Taxonomy Notes
Cysticapnos was described by Philip Miller in 1754 (published in Gard. Dict. Abr., 4th ed.) and is accepted in family Papaveraceae, order Ranunculales. GBIF records Phacocapnos Bernh. as a synonym of Cysticapnos, indicating these South African fumitory genera have at times been treated separately before being merged.
