They are putative \u0000members of the Aspleniifolia/Hookeriana Subgroup of the Grevillea Pteridifolia Group. Grevillea gilmourii is \u0000separated from G. macleayana (McGill) Olde & Marriott where it had previously been treated as the ‘Deua \u0000form’, a geographically disjunct, divided-leaf variant. The separate formal recognition of G. gilmourii here \u0000necessitates a revised delineation of G. macleayana to restrict it to populations with undivided leaves only, \u0000incorporating recent clarification to terminology in relation to leaf lobing. Grevillea milleriana is a recent \u0000discovery from the Maddens Plains area, south of Sydney. Known from a single plant, its recognition as a \u0000biological species rather than as a self-sown hybrid is discussed. All three species are linked morphologically \u0000and historically to the Victorian species G. barklyana F.Muell. ex Benth., which remains taxonomically \u0000unaltered from recent treatments. For the sake of convenience, all four species (G. barklyana, G. macleayana, \u0000G. gilmourii and G. milleriana) are grouped informally into an alliance, the Grevillea barklyana alliance, for \u0000which diagnostic characters are outlined and two identification keys are given. Both newly described species \u0000have divided leaves and are known from only small populations. Conservation recommendations are provided \u0000for both new species.","PeriodicalId":49440,"journal":{"name":"Telopea","volume":"110 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81643789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite several workers inspecting both the site and the trees growing there over this period, little consensus has been achieved on its taxonomic status. Various suggestions have been made that the entity was a new species with affinities to Eucalyptus dalrympleana, E. viminalis or E. bridgesiana, and at one time the unpublished manuscript name E. ‘wollemiensis’ was used. Because of the perceived small population size and threats posed by wildfire and other factors, the entity phrase name E. sp. Howes Swamp Creek (M.Doherty 26) was listed as an endangered taxon in both Commonwealth and State threatened species legislation. Our investigations over the last few years, involving field, seedling, and herbarium studies, have determined the original reference specimen designated for the phrase name is E. bridgesiana, and that the population from which the specimen was gathered comprises a hybrid swarm of E. bridgesiana × E. viminalis. Both parent species are present at the site, although the former species is seemingly very rare there. We recommend that E. sp. Howes Swamp Creek be removed from threatened species legislation, and that the names E. sp. Howes Swamp Creek (M.Doherty 26) and E. ‘wollemiensis’ ms be considered nomenclatural synonyms of E. bridgesiana.","PeriodicalId":49440,"journal":{"name":"Telopea","volume":"117 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79390155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Briggs, Carolyn L Connelly","doi":"10.7751/telopea15543","DOIUrl":"https://doi.org/10.7751/telopea15543","url":null,"abstract":"The diaspores of Anarthriaceae and Australian Restionaceae are seeds or small nuts and are illustrated by scanning electron microscopy or multifocus microscopy and considered in relation to a previously published phylogeny based on plastid genes. Loculicidal trilocular capsular fruits are the basal condition in the restiid clade, but indehiscent fruits have evolved many times. In the Australasian members, indehiscent fruits are found in Anarthriaceae (Hopkinsia); Restionaceae: Centrolepidoideae (Aphelia); Sporadanthoideae (Calorophus); Leptocarpoideae (Empodisma, Winifredia and the whole of the Leptocarpus and Desmocladus clades). Seeds of dehiscent fruits show a diversity of surface ornamentation with distinctive surface patterns characterising genera such as Lyginia, Chordifex and Loxocarya. Pericarps are membranous in subfam. Centrolepidoideae but in the Leptocarpus clade range from hyaline in much of Leptocarpus to hard and woody in Alexgeorgea and Hypolaena. Pericarps are parenchymatous in most of the Desmocladus clade, but woody in Catacolea. Indehiscent fruits are mostly shed with tepals and floral bracts attached or, in Baloskion and some Lepidobolus species, also with the subtending glume. Seed weights were not comprehensively sampled but vary from 0.08 mg in Centrolepis to >600 mg in Alexgeorgea, with most in the range 0.3–3 mg [dry weight]. The smaller weights are mostly either in perennials of habitats with more reliable rainfall or in ephemeral annuals that avoid drought by their brief growing season, but the association between seed type and habitat has not been investigated. We see no convincing evidence to link to Restionaceae the fossil taxon Restiocarpum and the Milfordia pollen that occurs with it in Eocene–Oligocene sediments of Queensland.","PeriodicalId":49440,"journal":{"name":"Telopea","volume":"94 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80662835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
