Pycnandra Benth., a member of subfamily Chrysophylloideae (Sapotaceae), is the largest endemic genus in New Caledonia and is subdivided into six subgenera. It circumscribes 59 species, plus an additional three described here, and nine additional species that remain undescribed for various reasons. We here use nrDNA data of ETS, ITS, and RPB2, analyse it within a Bayesian framework using BEAST, and place the new species in their respective subgenera. Pycnandra perplexa Swenson & Gâteblé is placed in subgenus Achradotypus and given a preliminary IUCN Red List assessment of Near Threatened (NT). It is confined to the ultramafic massif of southern Grande Terre and separated from the similar species P. griseosepala Vink, which is confined to non-ultramafic mountains north of the large southern ultramafic plateau. Pycnandra kopetoensis Munzinger & Swenson and P. margueriteae Munzinger & Swenson are two new micro-endemic species known only from their type localities, where habitats have been destroyed by deforestation, deliberate fires and mining activities. Pycnandra kopetoensis is named after Mount Kopéto, placed in subgenus Leptostylis, and given a preliminary assessment as Critically Endangered (CR). Pycnandra margueriteae is from a small remnant forest near Bourail and categorised as Critically Endangered (CR). Revised identification keys for subgenus Achradotypus, Leptostylis and Pycnandra are provided.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"34 1","pages":"510 - 525"},"PeriodicalIF":1.6,"publicationDate":"2021-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43371267","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}

Nicotiana is found predominantly in the Americas and Australia, but also has representatives in Africa and the Pacific Islands. All native Australian Nicotiana species belong to section Suaveolentes. The number of species in this section is uncertain and subject to revision. An example of this uncertainty is the taxonomic status of a South Australian Nicotiana accession colloquially termed ‘Corunna’. Here, we report sequences for nuclear and plastid markers for N. sp. Corunna (D.E.Symon 17088) and accessions of two other Australian species, N. burbidgeae and N. benthamiana. Phylogenetic comparison of these sequences with those of other members of Nicotiana places all three taxa in N. section Suaveolentes and shows that ‘Corunna’ represents a distinct phylogenetic lineage in a well supported clade along with N. goodspeedii, N. maritima, N. amplexicaulis and N. suaveolentes. Phenetic analysis of floral characters also supports recognition of N. sp. Corunna (D.E.Symon 17088) as a distinct species, which we describe here as Nicotiana paulineana Newbigin & P.M.Waterh., sp. nov.

The diagnostic characteristics and distinctiveness of plant taxa have traditionally been based on a combination of geographic and morphological discontinuity. Implicit within these concepts is the notion that morphological variation is fixed and that gene flow among taxa is limited. However, species complexes that comprise a range of more-or-less continuous morphotypes often confound such assumptions and resist formal taxonomic treatment. A range of independent data sources, namely, nucleotide sequences, volatile oils and traditional morphology, were used in an integrative approach to resolve the taxonomic structure within the geographically widespread species complex of Prostanthera lasianthos Labill. We concluded that no dataset has primacy in defining segregate taxa, and that a combination of morphological and molecular data was required to determine the taxa within. As a result, we amended the description of P. lasianthos sens. strict. and recognise the following five new segregate species: Prostanthera largiflorens B.J.Conn & K.Proft, P. lasiangustata J.Carrick ex B.J.Conn & K.Proft, P. rupicola B.J.Conn & K.Proft, P. subalpina B.J.Conn & K.Proft, and P. williamsii B.J.Conn & K.Proft.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"34 1","pages":"438 - 476"},"PeriodicalIF":1.6,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46244567","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 Acrotylaceae (Gigartinales) has been an obscure, puzzling red-algal family composed of six genera (Acrotylus, Amphiplexia, Antrocentrum, Claviclonium, Hennedya and Ranavalona) that have virtually no habit and vegetative features remotely in common. Excepting Amphiplexia, with two species, all are monotypic and, save for Ranavalona, endemic to the southern half of Australia, Ranavalona being known only by a single collection from southern Madagascar. The most noteworthy unifying feature of the genera is the cystocarps, in which carposporangial filaments grow into a hollow cavity from inner hull layers. In almost all other respects, apart from zonate tetrasporangia, there are no anatomical features that appear uniformly throughout the complex. Molecular studies indicate that the family is composed of the Acrotylaceae sensu stricto (for Acrotylus, Hennedya and Ranavalona) and the newly proposed Clavicloniaceae (for Claviclonium, Amphiplexia and Antrocentrum). We recognise a new species of Acrotylus (A. cryptographicus) and transfer Rhabdonia mollis Harvey and R. hamata Zanardini to Antrocentrum. Closest affinities of both families lie with the Dicranemataceae, Mychodeaceae and Mychodeophyllaceae of the Gigartinales. The South African genus Reinboldia, which is based on a single 19th century collection, has been questionably included in the Acrotylaceae previously but should, in our opinion, be excluded.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"34 1","pages":"305 - 326"},"PeriodicalIF":1.6,"publicationDate":"2021-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46802626","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}

Macro-morphological data were analysed to assess the distinctiveness and revise the taxonomy of 14 species, varieties and tag-named taxa in five informal species groups of ebracteate-erect forget-me-nots endemic to New Zealand.

Three species have two allopatric subspecies each in the South Island, distinguished by few, minor morphological characters, including Myosotis brockiei subsp. brockiei and M. brockiei subsp. dysis Courtney & Meudt subsp. nov., M. goyenii subsp. goyenii and M. goyenii subsp. infima Meudt & Heenan, and M. traversii subsp. cantabrica (L.B.Moore) Meudt comb. et stat. nov. and M. traversii subsp. traversii. Myosotis × cinerascens Petrie is hypothesised to be a rare natural hybrid involving M. traversii subsp. cantabrica and another species, possibly M. colensoi. Several vegetative and floral characteristics can distinguish the study taxa from one another and from other ebracteate-erect species. The nine species plus M. × cinerascens are included in the taxonomic treatment, and the key also includes other recently revised ebracteate-erect species.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"34 1","pages":"252 - 304"},"PeriodicalIF":1.6,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46251122","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}
