The Calcarata species complex in Viola sect. Melanium (Violaceae) is a group of species from Italy and neighbouring islands. The complex is of considerable evolutionary interest because several hypotheses about hybrid speciation within the group have been previously proposed. Because the Calcarata complex is not well characterized morphologically, we used 142 samples representing 92 (of c. 120) species of V. sect. Melanium plus three outgroup species. Nuclear ITS and ETS and plastid trnS–trnG intergenic spacer sequences were analysed to test the monophyly of the Calcarata complex and to infer relationships among the constituent species. Both nuclear and plastid sequences resulted in very limited phylogenetic resolution. Based on the nuclear dataset, most species of the Calcarata complex were recovered in four clades that also contained species not previously associated with the complex. Results from the plastid dataset recovered most species of the complex in a large polytomy. However, one larger clade containing only Calcarata complex species could be recovered, and species of all four nuclear clades were part of this larger plastid clade. The Calcarata complex clearly could not be resolved as monophyletic. We hypothesize that the lack of phylogenetic resolution may result mainly from frequent hybridization and hybrid speciation, processes that are well documented for Viola and V. sect. Melanium.

Salix rhoophila C. K. Schneid. was originally described based on three collections. The specimens in these collections belong to two different taxa: S. rhoophila as currently recognized and a species that until now has usually been called S. alfredii Goerz ex Rehder & Kobuski. The original material of S. polyclona C. K. Schneid. and S. mictotricha C. K. Schneid. also represent the same two species.

A nomenclatural study of 12 names and designations published by C. L. Willdenow was carried out. Two designations, “Amaranthus incomptus” (nomen nudum) and “A. japonicus” (pro synonymo), are not validly published. The ten validly published names are not yet typified except for A. chlorostachys Willd. Eight of the nine untypified names (A. angustifolius M. Bieb. ex Willd., A. bicolor Nocca ex Willd., A. campestris Willd., A. inamoenus Willd., A. lateus Willd., A. polystachyus Willd., A. strictus Willd. and A. tenuifolius Willd.) are lectotypified here on specimens preserved in the Willdenow Herbarium in Berlin (B), while the other name (A. hecticus Willd.) is lectotypified here on an illustration in Willdenow's Historia Amaranthorum. All the names in Amaranthus published by Willdenow are considered here to be heterotypic synonyms of currently accepted species names. The results obtained highlight how many Amaranthus species, especially in the past, were described on the basis of characters that have low or no taxonomic value, whereas morphological characters of the flowers have a high taxonomic value.

Recent molecular phylogenetic studies have shown that Hoya is paraphyletic without Absolmsia, Clemensiella, Madangia, and Micholitzia. These genera have been placed in synonymy with Hoya, but the monophyly of Hoya sensu lato relative to other genera of the broader Hoya group (Dischidia, Anatropanthus and Oreosparte, the latter two never included in a molecular phylogenetic analysis) remained unclear. Furthermore, no analysis has included both a significant sample of the Hoya group and outgroup genera of Marsdenieae to test the monophyly of the Hoya group and its position within the tribe. To address these gaps, we assembled two data sets: (1) the chloroplast trnT-trnL-trnF locus from 110 species and (2) three chloroplast loci (trnT-trnL-trnF, atpB-psbA spacer and matK) and two nuclear loci (nrDNA ITS and ETS) from 54 species. The Hoya group is monophyletic and nested in an Asian/Australian clade of Marsdenia s.l. The genus Hoya is paraphyletic unless Anatropanthus, Dischidia and Oreosparte are included. However, current evidence is not sufficient to synonymize Dischidia and Oreosparte with Hoya. Support for synonymy of Anatropanthus with Hoya is strong and the new name H. insularis is proposed. A clade of three new species with Oreosparte-like morphology is sister to the rest of the Hoya group and is described as the new genus Papuahoya.Citation: Rodda M., Simonsson N., Ercole E., Khew G., Niissalo M., Rahayu S. & Livshultz T. 2020: Phylogenetic studies in the Hoya group (Apocynaceae, Marsdenieae): the position of Anatropanthus and Oreosparte. – Willdenowia 50: 119–138. doi: https://doi.org/10.3372/wi.50.50112Version of record first published online on 27 March 2020 ahead of inclusion in April 2020 issue.
最近的分子系统发育研究表明，Hoya是一种没有Absolmsia, Clemensiella, Madangia和micholitia的副葡萄球菌。这些属被认为与霍亚属同义，但霍亚属与霍亚属其他属(Dischidia, Anatropanthus和Oreosparte，后两者从未被纳入分子系统发育分析)的单系关系尚不清楚。此外，没有分析包括霍亚族和马氏外群属的重要样本来测试霍亚族的单系性及其在部落中的地位。为了解决这些空白，我们收集了两个数据集:(1)来自110个物种的叶绿体trnT-trnL-trnF位点;(2)来自54个物种的三个叶绿体位点(trnT-trnL-trnF、atpB-psbA间隔和matK)和两个核位点(nrDNA ITS和ETS)。Hoya属是单系的，巢居于Marsdenia s.l的亚洲/澳大利亚分支中。Hoya属是副系的，除非包括Anatropanthus、Dischidia和Oreosparte。然而，目前的证据不足以将Dischidia和Oreosparte与Hoya同义。Anatropanthus与Hoya同义的说法得到了强有力的支持，并提出了新名称H. insularis。具有Oreosparte-like形态学的三个新种的分支是其他Hoya组的姐妹，被描述为新属Papuahoya。引用本文:Rodda M.， Simonsson N.， Ercole E.， Khew G.， Niissalo M.， Rahayu S. & Livshultz T. 2020: Hoya类群(Apocynaceae, Marsdenieae)的系统发育研究:Anatropanthus和Oreosparte的位置。-野生动物学报50:119-138。doi: https://doi.org/10.3372/wi.50.50112Version of record于2020年3月27日首次在线发表，并将于2020年4月被收录。

Molecular phylogenetic results had shown that Tephroseris, a genus differentiated from its closest relatives by its pinnately veined leaves, also contains species with palmate leaf venation. This had led to the conclusion that leaf venation is a homoplasious character in the lineage containing Tephroseris. We here take a closer look at leaf venation in Tephroseris and other species of Asteraceae–Senecioneae. We found that leaf venation in Tephroseris is distinct from leaf venation in Jacobaea vulgaris and Senecio vulgaris, which both have pinnately veined leaves as typical for most species of their respective genera, and that description of the leaves of Tephroseris as pinnately veined is incorrect. Instead, leaf venation in Tephroseris is very similar to that of upper cauline leaves of Ligularia stenocephala, a species with clearly palmately veined basal and lower cauline leaves. Both L. stenocephala and Tephroseris are part of the Ligularia–Cremanthodium–Parasenecio (L–C–P) complex. We conclude that leaf venation in Tephroseris is best regarded as derived from palmate leaf venation found in the large majority of species in the L–C–P complex, and presents no morphological obstacle to the circumscription of the genus.Citation: Kadereit J.

Kadereit, Katharina Bohley","doi":"10.3372/wi.50.50111","DOIUrl":"https://doi.org/10.3372/wi.50.50111","url":null,"abstract":"Molecular phylogenetic results had shown that Tephroseris, a genus differentiated from its closest relatives by its pinnately veined leaves, also contains species with palmate leaf venation. This had led to the conclusion that leaf venation is a homoplasious character in the lineage containing Tephroseris. We here take a closer look at leaf venation in Tephroseris and other species of Asteraceae–Senecioneae. We found that leaf venation in Tephroseris is distinct from leaf venation in Jacobaea vulgaris and Senecio vulgaris, which both have pinnately veined leaves as typical for most species of their respective genera, and that description of the leaves of Tephroseris as pinnately veined is incorrect. Instead, leaf venation in Tephroseris is very similar to that of upper cauline leaves of Ligularia stenocephala, a species with clearly palmately veined basal and lower cauline leaves. Both L. stenocephala and Tephroseris are part of the Ligularia–Cremanthodium–Parasenecio (L–C–P) complex. We conclude that leaf venation in Tephroseris is best regarded as derived from palmate leaf venation found in the large majority of species in the L–C–P complex, and presents no morphological obstacle to the circumscription of the genus.Citation: Kadereit J.
