The First Genome from the Basal Monocot Family Has Been Misnamed: Taxonomic Identity of Acorus tatarinowii (Acoraceae), a Source of Numerous Chemical Compounds of Pharmaceutical Importance

The basalmost monocot genus Acorus is well-known for its use in traditional oriental medicine. It comprises the groups of A. calamus and gramineus. A recent study recognized three species latter group, gramineus, macrospadiceus, tatarinowii. material currently known as tatarinowii has been extensively studied a source various chemical compounds producing first published genome Acorus, which important understanding origin evolution monocots. Using data from morphology, anatomy, biogeography, we argue that type does not match interpretation name adopted current literature herbarium collections (to taxon gramineus group Southeast Asia) but rather belongs to group. Moreover, macrospadiceus also cannot be used because it was invalidly published. Under narrow concept, other appropriate names should found or proposed plants named macrospadiceus. However, discourage concept insufficiently justified suggest recognizing single polymorphic species, s.l., at least until comprehensive taxonomic revision available.
