Piperales is an order of flowering plants (4,170 recognized species). It necessarily includes the family Piperaceae but other taxa have been included or disincluded variously over time. Well-known plants which may be included in this order include black pepper, kava, the many Peperomias, pepper elder, lizard's tail, birthwort, and wild ginger.[4] The two perianthless families Piperaceae and Saururaceae are mainly herbaceous plants possessing highly reduced flowers.[5][6]
Classification
[edit]APG system
[edit]In the APG IV system, of 2016, this order is placed in the clade magnoliids and is circumscribed as follows:[7]
- order Piperales
- family Aristolochiaceae (including Asaraceae, Hydnoraceae and Lactoridaceae)
- family Piperaceae
- family Saururaceae
| The current composition and phylogeny of the Piperales.[7][3] | |
This is an expansion from the APG system, of 1998, which used the same placement (in the magnoliids) but used this circumscription:
- order Piperales
- family Aristolochiaceae
- family Lactoridaceae
- family Piperaceae
- family Saururaceae
Earlier systems
[edit]The Cronquist system, of 1981, placed the order in the subclass Magnoliidae of class Magnoliopsida [=dicotyledons] and used this circumscription:
- order Piperales
- family Chloranthaceae
- family Piperaceae
- family Saururaceae
The Engler system, in its update of 1964, placed the order in subclassis Archichlamydeae in class Dicotyledoneae [=dicotyledons] and used this circumscription:
- order Piperales
- family Chloranthaceae
- family Lactoridaceae
- family Piperaceae
- family Saururaceae
The Wettstein system, latest version published in 1935, assigned the order to the Monochlamydeae in subclass Choripetalae of class Dicotyledones. It used the circumscription:
- order Piperales
- family Piperaceae
