The Arales are the sister group of the Alismatales, and are now included among them.
They are now included in the order Alismatales (see Update of the Angiosperm Phylogeny Group).
This former order includes the largest inflorescence, the titan arum, and the smallest flowering plant and smallest fruit, found in the duckweed, Wolffia.
It predominates in Alismatales and Zingiberales, and is a synapomorphy for some Liliales and Asparagales.
The first-branching monocotyledon, Acorus, has a secretory tapetum but among other early-braching taxa, most Alismatales (except Tofieldia) are plasmodial.
Successive microsporogenesis predominates in the monocotyledons although the simultaneous type is of systematic significance within some order s, e.g.
Order Alismatales contains the alismatids, a group of monocotyledons (Class Liliopsida).
At one point the alismatids were assigned to various distinct orders, but this approach produced polyphyletic groups, and so the whole group of families is now placed into a single order.
The alismatids as are the sister group of the Arales and the latter have sometimes been included here.

The monocots are considered to form a monophyletic group which evolved from an early
