Triuridales

From Wikipedia, the free encyclopedia

Triuridales is a botanical name of an order of flowering plants. A well-known system that used this name is the Cronquist system (1981), with this circumscription:

• order Triuridales

  family Petrosaviaceae

  family Triuridaceae

By habit, these plants were quite out of place in the subclass Alismatidae, where Cronquist placed this order. The APG II system, used here, leaves the first of these two families unassigned in the clade monocots while the second is moved to order Pandanales.
