A careful examination of historic taxonomic literature showed that the combination <i>T.clusii</i> was first proposed by Kerner and predates a currently used much younger isonym by Soják (1871 vs. 1971). One specimen, a karyovoucher from WU, is designated here as an epitype for the illegitimate name <i>Pyrethrumclusii</i>, upon which <i>Chrysanthemumclusii</i>, the basionym of <i>T.clusii</i>, is based. This designation aims to avoid ambiguity in the taxonomic interpretation of its previously selected lectotype. Based on examining the original material, a voucher from SIB is designated as a lectotype of the synonymic name <i>Chrysanthemumsubcorymbosum</i>, a basionym of Tanacetumcorymbosumsubsp.subcorymbosum. The last name is the only correct one in the rank of subspecies when <i>T.clusii</i> is alternatively treated as a separate subspecies within <i>T.corymbosum</i> s.l. In addition, one specimen from SAMU is designated here as a neotype of Pyrethrumcorymbosumf.macrocephalum, a newly discovered heterotypic synonym of <i>T.clusii</i>. The analysis of the current species distribution showed that <i>T.clusii</i> is native to Switzerland (confirmed!), Italy, Austria, Slovenia, Croatia, Bosnia and Herzegovina, Hungary (confirmed!), Slovakia, Poland, Ukraine, and Romania. Although currently not accepted for Switzerland in literature, <i>T.clusii</i> could be confirmed for the Swiss canton of the Grisons. The same applies for Hungary where, apart from the Bükk Mts in literature, new localities from the Kőszeg and Mátra Mts are presented here.

It was previously misidentified as <i>A.macrospadiceus</i> (Yamam.) F. N. Wei & Y. K. Li before. Through comparison of morphological characteristics, distribution locations, and type specimen, we determined that the elevation of A.gramineusvar.macrospadiceus Yamam to species status was incorrect. Therefore, we propose a formal description of a new species following nomenclature regulations. Based on morphological and plastid genomic data, this study formally describes and illustrates <i>Acorusshannai</i>, distributed in the Qiandongnan area of Guizhou Province and its surroundings, confirming it as a new species within the genus <i>Acorus</i>. This species is morphologically and phylogenetically distinct from other members of the <i>A.gramineus</i> group.
