Vieira, Gerardo A. Salazar, Cássio van den Berg","doi":"10.1002/tax.13124","DOIUrl":"https://doi.org/10.1002/tax.13124","url":null,"abstract":"After a confused taxonomic history, <i>Prosthechea</i> (Laeliinae, Orchidaceae) has been circumscribed in a broad sense to include species previously placed in <i>Encyclia</i> subg. <i>Osmophytum</i>. However, recent alternative classifications resurrecting old names such as <i>Anacheilium</i> and <i>Hormidium</i>, and proposing new genera such as <i>Euchile</i>, <i>Panarica</i>, <i>Pollardia</i>, and <i>Pseudencyclia</i> were presented, splitting <i>Prosthechea</i> into narrower genera. In this study, we provide a molecular phylogeny of <i>Prosthechea</i> to reassess alternative generic classifications and shed light on evolutionary aspects of this highly diverse Neotropical lineage. Eighty species of <i>Prosthechea</i> s.l. and 12 species of related genera were sampled. Bayesian and maximum parsimony analyses of sequences from three plastid regions (<i>rpl32-trnL</i>, <i>trnD-trnT</i>, <i>ycf1</i>) and nrITS were included. Possible conflicts between nuclear and plastid data were assessed with partitioned Bremer support. Ancestral state reconstructions of morphological characters relevant to the genus taxonomy are provided. Our results reinforce the monophyly of the lineage corresponding to a broad circumscription of <i>Prosthechea</i>. The small lineages corresponding to <i>Euchile</i>, <i>Panarica</i>, and <i>Hormidium</i> are monophyletic, whereas the larger <i>Anacheilium</i>, <i>Pollardia</i>, and <i>Pseudencyclia</i> are not monophyletic. Splitting <i>Prosthechea</i> into smaller genera is not supported by our phylogeny, and nonmonophyly also hinders the proposal of a comprehensive infrageneric classification. The phylogenetic relationships recovered reflect better the biogeographic patterns than the previously proposed morphological affinities, pointing to the existence of homoplastic floral traits within the genus. Conflicts between nuclear and plastid partitions were detected, suggesting a possible scenario of reticulate evolution.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"204 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139517393","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 Roemer &amp; Schultes, Syst. Veg. 7: 1350. 1830). The identity of <i>Arundo multiplex</i> Lour. has been questioned, with some authors preferring to use <i>Bambusa glaucescens</i> (Willd.) Siebold ex Merr. (in Philipp. J. Sci., C 7: 230. 1912). However, <i>Bambusa multiplex</i> is currently the more often used name for the species (e.g., Dransfield &amp; Widjaja, Pl. Resources SE Asia. 7, Bamboos: 65. 1995; Ohrnberger, Bamboos World: 266. 1999; Mabberley, Mabberley's Pl.-Book, ed. 4: 97. 2017; Vorontsova &amp; al., World Checkl.

This presents a problem because Loureiro cited “Arundarbor tenuis” of Rumphius (Herb. Amboin. 4: 1, t. 1. 1743) in the protologue of <i>Arundo multiplex</i>. “Arundarbor tenuis” is not <i>Bambusa multiplex</i>, but <i>Neololeba atra</i> (Lindl.) Widjaja (in Reinwardtia 11: 114. 1997). But in the absence of any Loureiro specimens or illustrations of <i>Arundo donax</i>, the Rumphian element must be considered in typifying the name, and Rumphius's plate seems to be the obligate lectotype as no indisputable Rumphius specimens are known (Van Steenis-Kruseman in Van Steenis, Fl. Males., ser. I, 1: 452 1950). This would make <i>Arundo multiplex</i> the earliest name for <i>Neololeba atra</i>, requiring a new combination in <i>Neololeba</i>. <i>Bambusa glaucescens</i> would become the correct name for what is now generally called <i>Bambusa multiplex</i>.</p>\u0000<p>This means that two established bamboo names, <i>Bambusa multiplex</i> and <i>Neololeba atra</i>, are currently under threat if nomenclatural rules are followed. The solution proposed here is to conserve <i>Arundo multiplex</i> with a conserved type to maintain the current usage of the names.

Nat., ed. 12: 263. 1767) was described by Carolus Linnaeus with a brief diagnosis indicating its resemblance to &lt;i&gt;O&lt;/i&gt;. &lt;i&gt;parviflora&lt;/i&gt; L. (Syst. Nat., ed. 10: 998. 1759), but differing by having non-emarginated teeth of the capsule apex and red-coloured papillae covering the stem (“fol. lanceolatis planis, caule purpurascente muricato. &lt;i&gt;Similis parviflorae, sed Fructus os non 8-fidus. Caulis puncta rubra sparsa&lt;/i&gt;.”). In addition, the origin of the species was stated to be Canada; however, no specimens or illustrations were cited in the protologue. In 1775, Johan A. Murray (in Novi Comment. Soc. Regiae Sci. Gott. 6: 24–26. 1775) provided a more detailed description and the first illustration of &lt;i&gt;O&lt;/i&gt;. &lt;i&gt;muricata&lt;/i&gt;. Murray's illustration (l.c.: t. 1; available at https://babel.hathitrust.org/cgi/pt?id=uc1.d0001408673&amp;view=1up&amp;seq=53&amp;seq=53) shows a plant similar to &lt;i&gt;O&lt;/i&gt;. &lt;i&gt;parviflora&lt;/i&gt;, with numerous side branches within the inflorescence area, divergent sepal tips and a straight tip of the inflorescence axis, and therefore it seems to be consistent with the protologue. Moreover, the illustration was cited in &lt;i&gt;Systema vegetabilium&lt;/i&gt; (Syst. Veg., ed. 14: 358. 1784) and in the subsequent edition of &lt;i&gt;Systema naturae&lt;/i&gt; by Johann F. Gmelin (Syst. Nat., ed. 13: 607. 1796).&lt;/p&gt;\u0000&lt;p&gt;Over the last 200 years, the name &lt;i&gt;Oenothera muricata&lt;/i&gt; has been interpreted differently by many taxonomists and geneticists, making its application very confusing. One of the main sources of confusion appeared with the illustration of &lt;i&gt;O. muricata&lt;/i&gt; in &lt;i&gt;Flora Danica&lt;/i&gt; (Oeder, Fl. Dan. 10(30): t. 1752. 1823, also available at http://www5.kb.dk/images/billed/2010/okt/billeder/object317208/da/). This illustration is significantly different from Murray's illustration and shows a plant with no flowering nor basal side branches, narrow leaves and, what is the most confusing, an explicitly curved top of the inflorescence axis. Such features point to &lt;i&gt;O&lt;/i&gt;. &lt;i&gt;oakesiana&lt;/i&gt; (A. Gray) J.W. Robbins ex S. Watson &amp; J.M. Coult. (in Gray, Manual, ed. 6: 190. 1890) or &lt;i&gt;O&lt;/i&gt;. &lt;i&gt;ammophila&lt;/i&gt; Focke (in Abh. Naturwiss. Vereins Bremen 18: 182. 1904) but not to &lt;i&gt;O&lt;/i&gt;. &lt;i&gt;parviflora&lt;/i&gt; nor any of its closest allies. Following the illustration in &lt;i&gt;Flora Danica&lt;/i&gt;, Hugo de Vries (Gruppenw.

(Phycol. Germ.: 203. 1845), nom. cons. in the order &lt;i&gt;Cladophorales&lt;/i&gt; is a widely distributed taxon with a total of 77 currently recognized species (Guiry &amp; Guiry, AlgaeBase. https://www.algaebase.org/search/species/?name=Chaetomorpha). Silva (in Hydrobiologia 2: 254. 1950) proposed that the name &lt;i&gt;Chaetomorpha&lt;/i&gt; be conserved against &lt;i&gt;Chloronitum&lt;/i&gt; Gaillon (in Cuvier, Dict. Sci. Nat. 53: 389. 1828) and &lt;i&gt;Spongopsis&lt;/i&gt; Kütz. (Phycol. General.: 261. 1843) because “neither &lt;i&gt;Chloronitum&lt;/i&gt; nor &lt;i&gt;Spongopsis&lt;/i&gt; had received recognition”, and that proposal was accepted. Silva (l.c.) also proposed &lt;i&gt;Chaetomorpha melagonium&lt;/i&gt; (Weber &amp; Mohr) Kütz. as the type of &lt;i&gt;Chaetomorpha&lt;/i&gt;, which was also accepted. With a current total of 372 entries in GenBank for &lt;i&gt;Chaetomorpha&lt;/i&gt;, including entries for the generitype and more than 30 other species currently assigned to the genus, with sequence data from several genes, it has become apparent that the generitype &lt;i&gt;C. melagonium&lt;/i&gt; does not group with any of the other species placed in the genus (Boedeker &amp; al. in J. Phycol. 52: 905. 2016, 54: 616. 2018). This difference is substantial, essentially at the level of genus. There appear to be two options to treat this untenable situation. The first would be to leave the genus intact with only the generitype &lt;i&gt;C&lt;/i&gt;. &lt;i&gt;melagonium&lt;/i&gt; left in the genus, on the basis of what is currently known, and to transfer the many other species demonstrated to be genetically different to a possible new genus or to a reinstated genus that is now treated as congeneric, such as &lt;i&gt;Spongopsis&lt;/i&gt;, typified by &lt;i&gt;S&lt;/i&gt;. &lt;i&gt;mediterranea&lt;/i&gt; Kütz. (l.c. 1843), although that genus was discounted in Silva's (l.c.) proposal to conserve &lt;i&gt;Chaetomorpha&lt;/i&gt;. The alternative option would be to propose to conserve &lt;i&gt;Chaetomorpha&lt;/i&gt; with a new conserved type, which would impact only on &lt;i&gt;C&lt;/i&gt;. &lt;i&gt;melagonium&lt;/i&gt;. In our opinion, a possible candidate to serve as the new conserved type is &lt;i&gt;Chaetomorpha linum&lt;/i&gt; (O.F. Müll.) Kütz. (l.c. 1845: 204), based on &lt;i&gt;Conferva linum&lt;/i&gt; O.F. Müll. (Fl. Dan. 5(13): 7, t. DCCLXXI. 1777), which is well recognized and widely occurring. It was one of the 15 species originally assigned to &lt;i&gt;Chaetomorpha&lt;/i&gt; by Kützing (l.c. 1845). &lt;i&gt;Chaetomorpha linum&lt;/i&gt; is one of the group of species that are not affiliated with &lt;i&gt;C. melagonium&lt;/i","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"10 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139065375","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}
