(Hydrangeaceae), a favorite among gardeners, comprises more than 80 species that are important understory plants in natural temperate and subtropical forests of the Northern Hemisphere. These species are hypervariable in morphology, especially in indumentum and floral characters, warranting a thorough exploration of the complex evolutionary history of morphological characters of the genus. Ideally, this is done within a robust phylogenetic framework with extensive taxon sampling. In this study, we propose a comprehensive taxonomic reassessment of <jats:italic>Hydrangea</jats:italic> based on a reconstruction of its molecular phylogeny based mainly on the chloroplast genome (plastome) and the most representative taxon sampling reported to date. Phylogenomic reconstruction yielded five well‐resolved major clades and three newly recognized subclades. Inspection of the 28 characters employed in traditional taxonomic revisions revealed homoplasy in many of these traits. Our results show that characters such as growth habit, woody stem type, number of enlarged marginal sepals, style and stamen number, fruit shape, and ovary position are useful for circumscribing infrageneric divisions. Unique synapomorphies are limited. For example, herb and subshrub growth habits are associated with all the species in <jats:italic>H.</jats:italic> sect. <jats:italic>Deinanthe</jats:italic> and sect. <jats:italic>Cardiandra</jats:italic>, respectively. Character state combinations are proposed for distinguishing infrageneric taxa. Based on a robust phylogenetic framework, our findings suggest a complex evolutionary history of <jats:italic>Hydrangea</jats:italic> morphological characters. Following the criterion of monophyly and considering the morphological consistency and synapomorphy of single and combined characters to diagnose relevant lineages, we update the classification of <jats:italic>Hydrangea</jats:italic> into 5 subgenera and 19 sections. Our proposed taxonomic scheme, based on a robust phylogenetic framework and in‐depth character study, provides an updated perspective on the infrageneric subdivision of <jats:italic>Hydrangea</jats:italic> s.l.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"44 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140202425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, Figueiredo &amp; Smith (in Phytotaxa 456: 299–300. 2020) proposed nomenclatural changes for the generic names &lt;i&gt;Brochoneura&lt;/i&gt; and &lt;i&gt;Cephalosphaera&lt;/i&gt;. Prior to their proposal, the name &lt;i&gt;Brochoneura&lt;/i&gt; had been applied to a group of three species in Madagascar (Sauquet in Bot. J. Linn. Soc. 146: 351–368. 2004) whereas &lt;i&gt;Cephalosphaera&lt;/i&gt; was exclusively applied to a single East African species. The proposed changes would have the name &lt;i&gt;Brochoneura&lt;/i&gt; instead applied to the East African species while the Malagasy group would be renamed &lt;i&gt;Neobrochoneura&lt;/i&gt; Figueiredo &amp; Gideon F. Sm. This proposed name swap by Figueiredo &amp; Smith followed their discovery of what may have been an unintentional name swap made by Otto Warburg, who originally published the name &lt;i&gt;Brochoneura&lt;/i&gt; for the East African species (Warburg in Engler, Pflanzenw. Ost-Afrikas C: 180. 1895) and subsequently expanded the genus to incorporate three Malagasy species originally included in &lt;i&gt;Myristica&lt;/i&gt; (Warburg in Nova Acta Acad. Caes. Leop.-Carol. German. Nat. Cur. 68: 237. 1897). Later, he published the monotypic East African genus &lt;i&gt;Cephalosphaera&lt;/i&gt; (Warburg in Bot. Jahrb. Syst. 33: 383. 1903) for &lt;i&gt;B. usambarensis&lt;/i&gt;, the original type of &lt;i&gt;Brochoneura&lt;/i&gt;, while restricting &lt;i&gt;Brochoneura&lt;/i&gt; to the Malagasy group. To rectify this centuries-old error by Warburg, the authors proposed to have &lt;i&gt;Brochoneura&lt;/i&gt; reinstated for the monotypic East African genus and give the Malagasy group a new name, &lt;i&gt;Neobrochoneura&lt;/i&gt;.&lt;/p&gt;\u0000&lt;p&gt;Although the name switch only affects a handful of species, it is nonetheless not helpful and may result in confusion, especially since the names in their pre-2020 sense have become well-established in the taxonomic and floristic literature. The name &lt;i&gt;Brochoneura&lt;/i&gt; has been applied to the Malagasy group for well over a century whereas it had only been applied to the East African taxon for a mere eight years, namely from 1895 to 1903. Both genera also have important economic uses.&lt;/p&gt;\u0000&lt;p&gt;The East African &lt;i&gt;Cephalosphaera&lt;/i&gt; (vernacular: mtambao) has historically been regarded as an economically valuable timber species, having been selectively logged since at least the mid-20th century (Waser &amp; al. in Tanzania J.

List: 151, no. 4317. 1831) listed “&lt;i&gt;C&lt;/i&gt;[&lt;i&gt;elastrus&lt;/i&gt;]. &lt;i&gt;Royleana&lt;/i&gt; Wall.”, based on a Royle collection. Subsequently, Royle (Ill. Bot. Himal. Mts.: 167. 1835) recorded “&lt;i&gt;C. spinosus&lt;/i&gt; nob. &lt;i&gt;Ic. ined&lt;/i&gt;. t. 73”. Both, being nomina nuda, are not validly published names. However, &lt;i&gt;Celastrus spinosus&lt;/i&gt; was later validated by Boissier (Fl. Orient. 2: 11. 1872).&lt;/p&gt;\u0000&lt;p&gt;Lawson (in Hooker, Fl. Brit. India 1: 620. 1875), while revising the family &lt;i&gt;Celastraceae&lt;/i&gt;, transferred a few members of &lt;i&gt;Celastrus&lt;/i&gt; to &lt;i&gt;Gymnosporia&lt;/i&gt;. He thus inadvertently validly published &lt;i&gt;Gymnosporia royleana&lt;/i&gt; seemingly based on the invalid “&lt;i&gt;C. royleanus&lt;/i&gt; Wall.” Lawson (l.c.) also included &lt;i&gt;C. spinosus&lt;/i&gt; Royle ex Boiss. as a synonym. His choice in accepting &lt;i&gt;G. royleana&lt;/i&gt; was seemingly purely based on what he considered to be priority of publication. This nomenclatural error under current rules made &lt;i&gt;G. royleana&lt;/i&gt; a superfluous illegitimate name under Art. 52.1 of the &lt;i&gt;ICN&lt;/i&gt; (Turland &amp; al. in Regnum Veg. 2018) as Lawson (l.c.) should have adopted the then-available epithet “&lt;i&gt;spinosa&lt;/i&gt;”. It is thus automatically typified by the type of &lt;i&gt;C. spinosus&lt;/i&gt; Boiss. (Art. 7.5). Boissier (l.c.) cited two gatherings from Afghanistan (“Griffith pl. exs. 1245! et Herb. East lnd. Comp. n&lt;sup&gt;o&lt;/sup&gt; 1991!”). During our search for type specimens, we traced eight specimens, six at K [barcodes K001325915, K001325916, K001325917, K001325918, K001325919, K001325920] and one each at CAL [No. 86591] and DD [No. 1991]. The sheet K001325915 is well preserved, precisely matching with the protologue, bearing one flowering and a fruiting twig of a single gathering [1245] without any confusing and illegible labels. Hence, it is selected above as the lectotype; the specimen K001325917 appears to be a duplicate of it.&lt;/p&gt;\u0000&lt;p&gt;Cufodontis (in Senckenberg. Biol. 43: 313. 1962) transferred &lt;i&gt;Gymnosporia royleana&lt;/i&gt; to &lt;i&gt;Maytenus&lt;/i&gt; as &lt;i&gt;M. royleana&lt;/i&gt; Cufod., which is a legitimate name, as the existence of &lt;i&gt;M. spinosa&lt;/i&gt; (Griseb.) Lourteig &amp; O'Donell (in Natura (Buenos Aires) 1: 188. 1955) precluded the adoption of Boissier's epithet ‘&lt;i&gt;spinosa&lt;/i&gt;’ in &lt;i&gt;Maytenus&lt;/i&gt;. Raju &amp; Babu (in Bull.

Staude (Schwämme Mitteldeutschl.: xxviii, 122. 1857) is a genus of the family &lt;i&gt;Clitocybaceae&lt;/i&gt; Vizzini &amp; al. (in Index Fungorum 462: 1. 2020), characterized by the clitocyboid basidiome typically with a depressed pileus and decurrent lamellae. The genus currently encompasses approximately 500 species, according to the Index Fungorum database (www.indexfungorum.org, accessed on 1 Oct 2023). A substantial proportion of these species is included in specific monographs of Harmaja (in Karstenia 10: 5–168. 1969) and Bigelow (N. Amer. Sp. Clitocybe 1. 1982; 2. 1985). The genus exhibits a wide global distribution, and has also been extensively documented in various comprehensive monographs, journals or field guides from Africa (e.g., Pegler in Persoonia 4: 73–124. 1966), Asia (e.g., Li &amp; al., Atlas Chinese Macrofungal Resources. 2015), Europe (e.g., Bas &amp; al., Fl. Agaricina Neerl. 3. 1995), North America (e.g., Phillips, Mushrooms Other Fungi N. Amer. 2005), South America (e.g., Dennis, Fungus Fl. Venezuela. 1970), Australia (Grgurinovic, Larger Fungi S. Australia. 1997), and New Zealand (e.g., Cooper, New Zealand Clitocybaceae. 2016). The genus has been demonstrated to serve as a valuable reservoir of edible and medicinal resources (Wu &amp; al. in Fungal Diversity 98: 1–76. 2019). Meanwhile, the genus has also been found to contain numerous muscarine-producing poisonous mushrooms (Genest &amp; al. in J. Pharmacol. Sci. 57: 331–333. 1968; He &amp; al. in Fungal Diversity 123: 1–47. 2023).&lt;/p&gt;\u0000&lt;p&gt;Recent multi-locus phylogenetic and phylogenomic analyses of &lt;i&gt;Clitocybaceae&lt;/i&gt;, conducted by He &amp; al. (l.c.), revealed the presence of six generic clades based on comprehensive assessments of genetic distance and divergence time. In the phylograms, the genera &lt;i&gt;Dendrocollybia&lt;/i&gt;, &lt;i&gt;Lepista&lt;/i&gt; s.str., &lt;i&gt;Pseudolyophyllum&lt;/i&gt;, and &lt;i&gt;Singerocybe&lt;/i&gt; each formed a distinct clade, whereas &lt;i&gt;Clitocybe&lt;/i&gt; fell into the remaining two generic clades. The first clade exhibited robustness, encompassing the majority of traditional &lt;i&gt;Clitocybe&lt;/i&gt;, &lt;i&gt;Collybia&lt;/i&gt;, and &lt;i&gt;Lepista&lt;/i&gt; species, while the second clade comprised only a few &lt;i&gt;Clitocybe&lt;/i&gt; species.&lt;/p&gt;\u0000&lt;p&gt;The first generic clade can be divided into four subclades, including species previously classified under (1) &lt;i&gt;Clitocybe&lt;/i&gt; sect. &lt;i&gt;Candicantes&lt;/i&gt; (Quél.)

In spite of this, its use has been most discontinuous for over two centuries and its interpretation remains unstable and still seriously varying among authors.&lt;/p&gt;\u0000&lt;p&gt;Description of &lt;i&gt;Cheiranthus armeniacus&lt;/i&gt; was based on cultivated plants grown from seeds collected on Mount Ararat in eastern Anatolia. No relevant herbarium material seems to be extant, as suggested by Davis &amp; al. (Fl. Turkey 10: 55. 1988; the author's search in K and elsewhere also failed), and trichome morphology, critically important in the taxonomy of &lt;i&gt;Erysimum&lt;/i&gt;, was not described in the protologue. However, the original illustration, designated above as lectotype, showing the characteristic habit along with some mentioned details (e.g., stout sulcate stem, big and profoundly bilobed stigmas, erect young fruits) allows for defining its affinity. Bieberstein (Fl. Taur.-Caucas. 2: 118. 1808) was the first to consider &lt;i&gt;C. armeniacus&lt;/i&gt; conspecific with &lt;i&gt;C. ibericus&lt;/i&gt; Adams (in Beitr.

Nat. 2: 498. 1821) for the species. This synonymy was included in early synoptic accounts (Sprengel, Syst. Veg. 2: 907. 1825; Steudel, Nomencl. Bot., ed. 2, 1: 346. 1840; Jackson in Index Kew. 1: 508, 892. 1893) and in a few floras (Ledebour, Fl. Ross. 1: 187. 1841 [“1842”]; Boissier, Fl.

The first genus comprises approximately 360 species from almost all parts of the world, while the second contains a total of 8 species from tropical Africa and the Arabian Peninsula. Since 1977, the relationships between <i>Verbascum</i> and <i>Rhabdotosperma</i> continue to be contested. The present study aims to present the phylogenetic relationships and status among <i>Verbascum</i> species in the Arabian Peninsula. For phylogenetic analyses, maximum parsimony and Bayesian inference were performed. In total, 236 DNA sequences from 59 specimens of Arabian <i>Verbascum</i> were analysed. The phylogenetic analysis of one nuclear (ITS) and three chloroplastic (<i>rbcL</i>, <i>matK</i>, <i>trnL</i>) markers confirmed the monophyly of <i>Verbascum</i>, including the genus <i>Rhabdotosperma</i>. In addition to presenting novel phylogenetic relationships among the different <i>Verbascum</i> species in the Arabian Peninsula, our study reduced the species count of Arabian <i>Verbascum</i> to 16. Moreover, the phylogenetic analysis strongly supports the reinstatement of the genus <i>Rhabdotosperma</i> into <i>Verbascum</i> based on the Bayesian and maximum parsimony analyses.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"32 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140073020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to make this variation comprehensible, the species was divided into five forms, which remain distinct in cultivation (Robson in Plantsman 1: 193–200. 1980, in Phytotaxa 4: 26. 2010). Moreover, there are several ornamental cultivars of &lt;i&gt;H&lt;/i&gt;. &lt;i&gt;olympicum&lt;/i&gt; (e.g., ‘Citrinum’, ‘Sulphureum’, ‘Variegatum’) (see https://ecuador.inaturalist.org/taxa/567176-Hypericum-olympicum#cite_note-30).&lt;/p&gt;\u0000&lt;p&gt;Aerial parts of the plant are used in folk medicine for stomach ache, inflamed wounds and cuts (Tuzlacı &amp; al. in Fitoterapia 72: 323–343. 2001), thus its essential oil composition (Gudžić &amp; al. in Flavour Fragr.
