Per D.J. Mabberley ("The Plant Book")

Acorus is now Acoraceae.... "formerly included in Araceae but habit and
other morphological as well as molecular features exclude it; it has been
argued that the family is 'basal' to the Monocots in being intermediate
between several orders, having similarities with Araceae & Typhaceae but the
presence of oil idioblasts & absence of raphides reminiscent of
Zingiberaceae though it is outstanding in its well-developed perisperm
devoid of starch."

Acorus is now in Acoraceae (a family originally pblished in the early 19th
C) and is also removd entirely from the Alismatales (the order in which the
Araceae belongs) into its own order, the Acorales.

Acorus is widely considered to be the most primitive living Monocot.
