{"title":"Phylogeny and reclassification of Lampranthus (Ruschieae, Aizoaceae) in southern Africa","authors":"Cornelia Klak, Pavel Hanáček, Peter V. Bruyns","doi":"10.1002/tax.13166","DOIUrl":"https://doi.org/10.1002/tax.13166","url":null,"abstract":"<jats:italic>Lampranthus</jats:italic> consists of 85 species of succulent perennials which are all endemic to southern Africa. Most of its species are restricted to <jats:italic>fynbos</jats:italic> and regenerate in large numbers after fires. We use nine chloroplast markers to generate a phylogeny with a dense sampling of <jats:italic>Lampranthus</jats:italic> and some taxa which may be closely related to it. While we found that most of the species belong to one strongly supported “core” clade, we also found three minor clades of <jats:italic>Lampranthus</jats:italic> that fall outside this core. For <jats:italic>Lampranthus</jats:italic> we set up a new classification of three subgenera. The clades forming <jats:italic>L.</jats:italic> subg. <jats:italic>Adunci</jats:italic> (3 spp.) and subg. <jats:italic>Calcarati</jats:italic> (1 sp.) are unresolved within the Ruschieae and we treat them as subgenera until their relationships are clarified. Three sections are proposed for <jats:italic>L.</jats:italic> subg. <jats:italic>Lampranthus</jats:italic> and we also suggest new synonymy for several species in <jats:italic>L.</jats:italic> sect. <jats:italic>Lampranthus</jats:italic> (65 spp.) and sect. <jats:italic>Blandi</jats:italic> (15 spp.). <jats:italic>Roosia</jats:italic> and the type species for <jats:italic>Esterhuysenia</jats:italic> are nested in <jats:italic>L.</jats:italic> sect. <jats:italic>Blandi</jats:italic> and so these genera are subsumed under <jats:italic>Lampranthus</jats:italic>. <jats:italic>Esterhuysenia stokoei</jats:italic> forms part of <jats:italic>Lampranthus</jats:italic> and is the sole member of a new section within <jats:italic>L.</jats:italic> subg. <jats:italic>Lampranthus.</jats:italic> The two larger sections of <jats:italic>L.</jats:italic> subg. <jats:italic>Lampranthus</jats:italic> show different evolutionary trends and distributions: <jats:italic>Lampranthus</jats:italic> sect. <jats:italic>Lampranthus</jats:italic> contains more species, they are mostly in the winter rainfall region of the Western Cape and they have a greater range of floral shapes and colours. <jats:italic>Lampranthus</jats:italic> sect. <jats:italic>Blandi</jats:italic> contains a single species in the Kamiesberg, in the Northern Cape, while most of its species occur along the southern coast of southern Africa eastwards to southern Natal. These species are florally less diverse. Two species of <jats:italic>Lampranthus</jats:italic> are moved to a new genus, <jats:italic>Malephoropsis</jats:italic> gen. nov. These are unrelated to the rest of <jats:italic>Lampranthus</jats:italic> and they fall among species of <jats:italic>Malephora</jats:italic>, <jats:italic>Disphyma</jats:italic> and <jats:italic>Gibbaeum</jats:italic> with which they share softly corky branches, mesomorphic leaves and only slightly woody fruits with false septa.

However, a widely accepted tribal classification for Papaveraceae remains lacking. In this study, we used a sampling covering all 48 of the currently recognized genera of Papaveraceae. Our study is to employ broad morphological data in combination with sequence data from two nuclear and seven plastid DNA regions to reconstruct phylogenetic relationships within the family. Our analyses indicate that Pteridophylloideae is sister to the clade containing Hypecooideae and Fumarioideae, and these three lineages are in turn sister to Papaveroideae. The alternative topologies constraining Pteridophylloideae as sister to the other poppy species, to Papaveroideae or to Hypecooideae, as recovered in previous studies, are all rejected. Fumarioideae contains nine main clades, and Fumarieae is nested in traditional Corydaleae. Within Papaveroideae, three main clades are recovered and Platystemoneae is embedded within traditional Papavereae. Both topologies constraining traditional Corydaleae or Papavereae as monophyletic are significantly rejected. Within this phylogenetic framework, the evolution of selected characters is inferred and diagnostic morphological characters at different taxonomic levels are identified and discussed. Based on morphological and molecular evidence, a new tribal classification of Papaveraceae is presented, in which 4 subfamilies, 14 tribes (including 7 newly described tribes), and 43 genera are recognized.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"337 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140941258","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}
