This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots. Some older studies indicated that it was placed in a lineage (the order Alismatales), that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots (e.g., Alismataceae, Posidoniaceae). However, modern phylogenetic studies demonstrate that Acorus is sister to all other monocots. Common names include calamus and sweet flag.
Although the family Acoraceae was originally described in 1820, since then Acorus has traditionally been included in Araceae in most classification systems, as in the Cronquist system. The family has recently been resurrected as molecular systematic studies have shown that Acorus is not closely related to Araceae or any other monocot family, leading plant systematists to place the genus and family in its own order. This placement currently lacks support from traditional plant morphology studies, and some taxonomists still place it as a subfamily of Araceae, in the order Alismatales. The APG III system recognizes order Acorales, distinct from the Alismatales, and as the sister group to all other monocots. This relationship is confirmed by more recent phylogenetic studies.
The whole sequences with one IR region of 42 taxa of angiosperms were aligned using MAFFT (Katoh and Standley 2013), then gaps were trimmed by trimAl (Capella-Gutiérrez et al. 2009) using the command ‘-gt 0.6 -cons 60’. For Maximum Likelihood analyses, we used RAxML (Stamatakis et al. 2008) using GTRGAMMAI model with 1000 bootstraps to reconstruct phylogeny of A. tatarinowii. Phylogenetic analysis showed that Acorales was the most basal order of monocots, and A. tatarinowii was sister to A. gramineus (Figure 1). DNA polymorphism analysis of four Acorus plastomes with one IR showed that there are 1302 variable and 601 parsimony-informative sites, respectively, and high variable and parsimony-informative regions occur at trnT (Source: www.tandfonline.com)
