Juncales is an order of flowering plants. In the Engler system (update, of 1964) and in the Cronquist system (of 1981, which placed this order in subclass Commelinidae) it is circumscribed as:
family Juncaceae
family Thurniaceae
However, the Thorne system (1992) accepts it as consisting of :
family Prioniaceae
family Thurniaceae
family Juncaceae
family Cyperaceae
The APG II system, used here, assigns the plants involved to the order Poales.
