The Utricularia dichotoma Labill. complex is a morphologically and ecologically variable group of closely related taxa with a mostly temperate distribution across New Zealand, New Caledonia and Australia. Taxonomic boundaries within the complex have been the subject of speculation, with several previously recognised species being synonymised after a nomenclatural revision. We sampled 296 populations representing all known taxa; 223 accessions were used in the full phylogenetic analysis based on two non-coding chloroplast regions (rps16, trnD–T) and two nuclear ribosomal spacers (external transcribed spacer, ETS; internal transcribed spacer-1, ITS-1), whereas the remaining accessions were identified by using ITS-1 barcodes. We found strong support for a paraphyletic U. dichotoma, with accessions matching the type material of that name grouped within a polytomy that includes clades containing accessions of U. monanthos Hook.f and U. novae-zelandiae Hook.f. Specific statuses for five recently described species previously included in U. dichotoma s.l. do not fall within this polytomy, nor do the two species U. oppositiflora R.Br. and U. speciosa R.Br. resurrected from synonymy of U. dichotoma. All sampled accessions from New Zealand form a single clade within U. dichotoma as recognised here. We here propose that seven clades recovered here be recognised as subspecies, and describe eight new subspecies, including two new combinations. We also propose that the monophyletic clade sister to U. beaugleholei Gassin be assigned to subspecies rank under that name.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2020-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43209828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relevant type material is illustrated in detail. A list of 79 morphoanatomical characters and character states used by previous authors (since 1928) to delimit or identify species of Jania was compiled. Of these, nine were useful for delimiting species occurring in south-eastern Australia. Most can be delimited using a single diagnostic character, but Jania pedunculata J.V.Lamour. is highly variable and is distinguished from J. crassa J.V.Lamour. by using several overlapping characters. Twelve additional names have been recorded for south-eastern Australia. The types of seven of these were examined during the present study or in recent publications. Types of five entities could not be examined, because type material had not been designated or was not available for examination or the name was not validly published.

The taxonomic limits of Styphelia (Ericaceae, Epacridoideae, Styphelieae) have been contentious since the genus was first described. At one extreme, it has been circumscribed so broadly as to include most epacrids with drupaceous fruit, at the other, to include only those species that also have long-exserted anthers and styles. Recent molecular phylogenetic analyses have indicated that while all previous circumscriptions of Styphelia are non-monophyletic, a large clade (the Astroloma–Styphelia clade) is consistently well supported. This clade comprises Astroloma, in part (i.e. section Stomarrhena sensu Bentham), Coleanthera, Croninia, Leucopogon, in part (i.e. section Pleuranthus sensu Bentham) and Styphelia sensu Bentham. On the basis of those analyses, we here recircumscribe Styphelia phylogenetically to include all species belonging to the Styphelia–Astroloma clade. The 146 taxa occur mostly in Australia, with smaller numbers in New Zealand, New Caledonia (1 species extends to Fiji and Vanuatu) and Malesia. An additional 74 phrase-named taxa belong to this clade, including 70 from Western Australia and 4 from eastern Australia (all other Australian states and territories). The Styphelia floras of Western Australia, eastern Australia, New Caledonia and Malesia are each endemic or nearly so; 1 species (S. nesophila (DC.) Sleumer) is shared between New Zealand and eastern Australia, and 2 species (S. cordifolia (Lindl.) F.Muell. and S. woodsii (F.Muell.) F.Muell.) are shared between Western Australia and eastern Australia. An amended diagnosis of Styphelia is provided, new combinations are made for 25 taxa, and new names published for another 9.

The genus Philodendron Schott comprises the following three currently accepted subgenenera: P. subg. Philodendron, P. subg. Pteromischum and P. subg.

In the present study, we examined anatomically samples of adventitious roots in species of the group, so as to establish aspects relevant for taxonomic purposes. The anatomical analyses emphasised the characteristics of the steles in cross-sections of the root samples from regions near the apex to the most mature zones. A species of a closely related genus Adelonema, namely A. crinipes, was included in the study to clarify the results. Our results indicated notable differences in the species of the subgenus Meconostigma, mainly in terms of the presence (and variations) of a lobed stele, whereas the cylindrical stele stood out among the common characteristics in P. subg. Philodendron, P. subg. Pteromischum and the related species A. crinipes. Moreover, the characteristics shared by P. subg. Philodendron and P. subg. Pteromischum corroborated the phylogenetic hypothesis that these two taxa were more closely related to one another than to P. subg.

The Capparaceae are a family of plants associated mainly with dry areas, which have produced climatic constraints and a limited geographic distribution. This family is considered endemic in the Neotropical seasonally dry forest (NSDF) and, therefore, a model to analyse the NSDF biogeography. We conducted a track analysis of Neotropical species of Capparaceae to identify generalised tracks that recover ancestral biotas of NSDF nuclei, employing 7602 data points for 104 species. Individual tracks were obtained using Prim’s algorithm and generalised tracks were identified using parsimony analysis of endemicity with progressive character elimination. We found six generalised tracks and four panbiogeographic nodes mainly located in the NSDF. Generalised tracks recovered the ancestral biotas of NSDF distributed among the central Andean coast, central inter-Andean valleys (Ecuador), Tarapoto–Quillabamba, Apurimac–Mantaro (Peru) and Piedmont (Bolivia) NSDF nuclei. Also, the pattern of distribution of Capparaceae recovered old connections between northern South America and the inter-Andean valleys. However, we also found generalised tracks located over the Isthmus of Panama and Amazonian–Magdalena valley moist forest, suggesting that the distribution pattern in this family was influenced not only by NSDF climatic constraints, but also by geological events such as the emergence of the Isthmus and Andean uplift.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2020-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB18058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49135114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The genus Vachellia Wight & Arn. has a pantropical distribution, with species being distributed through Africa, the Americas, Asia and Australia. The relationships among the lineages from Africa and America are well understood, but the phylogenetic placement and evolutionary origins of the Australian species of Vachellia are not known. We, therefore, sequenced four plastid genes from representatives of each of the nine Australian species of Vachellia, and used Bayesian inference to assess the phylogenetic placement of these lineages, and a relaxed molecular clock to assess the timing of diversification. The Australian species of Vachellia form a well-supported monophyletic clade, with molecular-dating analysis suggesting a single dispersal into Australia 6.5 million years ago (95% range 13.9–2.7 million years ago). Diversification of the Australian clade commenced more recently, c. 3.1 million years ago (95% range 9.2–1.2 million years ago), perhaps driven by the increased aridification of Australia at this time. The closest relatives to the Australian Vachellia were not from the Malesian bioregion, suggesting either a long-distance dispersal from Africa, or two separate migrations through Asia. These results not only improve our understanding of the biogeography of Vachellia species, but also have significant implications for the biological control of invasive Vachellia species in Australia.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48594972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
