(′pip·ə′rā·lēz)

(botany) An order of dicotyledonous herbaceous plants marked by ethereal oil cells, uniaperturate pollen, and reduced crowded flowers with orthotropous ovules.


A small order of flowering plants (3600 species) in the eumagnoliid group, which is composed of three anomalously woody vines (shrubs) or herbaceous families—the pipeworts (Aristolochiaceae), the black pepper family (Piperaceae), and the lizard's tail family (Saururaceae). The last two families have reduced flowers in dense spikelike flower stems, and the first has medium-sized to enormous flowers that often trap insects for a period before releasing them, covered with pollen.

Black pepper comes from Piper nigrum and betel nuts from P. betle. Several species of Aristolochia have medicinal properties, and some genera in each of these families are commonly grown ornamentals in the temperate zones or house plants, such as Asarum (wild ginger), Peperomia (pepper elders), and Houttuynia. See also Eumagnoliids; Laurales; Magnoliales; Monocotyledons.

Classification

APG system

In the APG II system, of 2003, this order is placed in the clade magnoliids and is circumscribed as follows:

order Piperales
family Aristolochiaceae
family Hydnoraceae
family Lactoridaceae
family Piperaceae
family Saururaceae
Magnoliidae


Canellales



Piperales


Aristolochiaceae



Hydnoraceae



Lactoridaceae





Piperaceae



Saururaceae








Laurales



Magnoliales




The current composition and phylogeny of the Piperales.[1][2]

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Lactoridaceae is now no longer maintained; its sole genus Lactoris is placed in Aristolochiaceae.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