Vernacular name

Piperales is a botanical name for an order of flowering plants. It necessarily includes the family Piperaceae but otherwise has been treated variously over time. Well-known plants which may be included in this order include black pepper, kava, lizard's tail, birthwort, and wild ginger.


Classification

APG system

In the APG II system, of 2003, this order is placed in the clade magnoliids

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

Lactoridaceae is now no longer maintained; its sole genus Lactoris is placed in Aristolochiaceae.

Earlier systems

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
