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.

Target capture (aka Hyb-Seq) allows researchers to sequence hundreds of genomic regions (loci) of their choosing, at relatively low cost per sample, from which to derive phylogenetically informative data. Although this highly flexible and widely applicable method has rightly earned its place as the field's <i>de facto</i> standard, it does not come without its challenges. In particular, users have to specify which loci to sequence-a surprisingly difficult task, especially when working with non-model groups, as it requires pre-existing genomic resources in the form of assembled genomes and/or transcriptomes. In the absence of taxon-specific genomic resources, target sets exist that are designed to work across broad taxonomic scales. However, the highly conserved loci that they target may lack informativeness for difficult phylogenetic problems, such as that presented by the rapid radiation of <i>Erica</i> in southern Africa. We designed a target set for <i>Erica</i> phylogenomics intended to maximise informativeness and minimise paralogy while maintaining universality by including genes from the widely used Angiosperms353 set. Comprising just over 300 genes, the targets had excellent recovery rates in roughly 90 <i>Erica</i> species as well as outgroups from <i>Calluna</i>, <i>Daboecia</i>, and <i>Rhododendron</i>, and had high information content as measured by parsimony informative sites and Quartet Internode Resolution Probability (QIRP) at shallow nodes. Notably, QIRP was positively correlated with intron content, while including introns in targets-rather than recovering them via exon-flanking \"bycatch\"-substantially improved intron recovery.
