Grevillea gilmourii Olde and G. milleriana Olde, two species new to science, are described. They are putative members of the Aspleniifolia/Hookeriana Subgroup of the Grevillea Pteridifolia Group. Grevillea gilmourii is separated from G. macleayana (McGill) Olde & Marriott where it had previously been treated as the ‘Deua form’, a geographically disjunct, divided-leaf variant. The separate formal recognition of G. gilmourii here necessitates a revised delineation of G. macleayana to restrict it to populations with undivided leaves only, incorporating recent clarification to terminology in relation to leaf lobing. Grevillea milleriana is a recent discovery from the Maddens Plains area, south of Sydney. Known from a single plant, its recognition as a biological species rather than as a self-sown hybrid is discussed. All three species are linked morphologically and historically to the Victorian species G. barklyana F.Muell. ex Benth., which remains taxonomically unaltered from recent treatments. For the sake of convenience, all four species (G. barklyana, G. macleayana, G. gilmourii and G. milleriana) are grouped informally into an alliance, the Grevillea barklyana alliance, for which diagnostic characters are outlined and two identification keys are given. Both newly described species have divided leaves and are known from only small populations. Conservation recommendations are provided for both new species.
描述了两种科学上的新物种——格列维尔(Grevillea gilmourii Olde)和千年虫(G. milleniana Olde)。它们被认为是灰拟蕨类植物组的Aspleniifolia/Hookeriana亚组的成员。Grevillea gilmourii是从G. macleayana (McGill) Olde & Marriott分离出来的,在那里它以前被视为“Deua形式”,一种地理上不相交的分叶变体。这里对G. gilmourii的单独正式承认需要修订G. macleayana的描述,以将其限制为仅具有未分裂叶片的种群,并结合最近对与叶片分叶有关的术语的澄清。千年虫是最近在悉尼南部马登斯平原地区发现的。从一个单一的植物,它的识别作为一个生物物种,而不是作为自种杂交讨论。这三个物种在形态和历史上都与维多利亚时代的物种G. barklyana F.Muell有联系。Benth交货。它在分类学上与最近的治疗方法保持不变。为了方便起见,所有四个物种(G. barklyana, G. macleayana, G. gilmourii和G. milleriana)被非正式地归为一个联盟,即Grevillea barklyana联盟,概述了该联盟的诊断特征并给出了两个识别关键。这两种新发现的物种都有分裂的叶子,而且只在很小的种群中被发现。对这两个新物种提出了保护建议。

We here describe Machaerina ascendens R.L.Barrett & K.L.Wilson as a new species from swamps within forests in the far south-west of Western Australia. The new species is readily identifiable by its scrambling habit and compressed, multi-noded culms, features which separate it from all other Australian species. The clearly distichous glumes, few hypogynous scales fused at the base into a ring and prominently stipitate nutlets are also unusual features in Machaerina Vahl. Machaerina ascendens is highly range-restricted by its specific habitat and appears to qualify for listing as Endangered. Study of all names applicable to the current concept of Machaerina revealed an earlier name for the eastern Australian species Machaerina nuda (Steud.) J.Kern, and a new combination is provided here for Schoenus abbreviatus Nees as Machaerina abbreviata (Nees) R.L.Barrett & K.L.Wilson.
在这里,我们将Machaerina ascendens R.L.Barrett和K.L.Wilson描述为来自西澳大利亚西南部森林内沼泽的新物种。这个新物种很容易通过它的攀援习性和压缩的多节秆来识别,这些特征使它与所有其他澳大利亚物种分开。明显的二列颖片,在基部融合成环形的少数下位鳞片和显著的具柄小坚果也是在mahaerina Vahl中不寻常的特征。由于其特定的栖息地,其活动范围受到高度限制,似乎有资格被列为濒危物种。对所有适用于当前Machaerina概念的名称的研究揭示了澳大利亚东部物种Machaerina nuda (Steud)的早期名称。本文将Schoenus缩写词Nees与R.L.Barrett和K.L.Wilson的缩写词(Nees)进行了新的组合。

Resolution of a 35-year taxonomic dilemma: Eucalyptus sp. Howes Swamp Creek (Myrtaceae) from eastern Wollemi National Park, New South Wales 一个长达35年的分类困境的解决:来自新南威尔士州沃勒米国家公园东部的桉树sp. Howes Swamp Creek(金桃科)

The identity of a population of eucalypts from Howes Swamp Creek in the eastern part of Wollemi National Park in New South Wales has remained unresolved for over 35 years. 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.
来自新南威尔士州沃勒米国家公园东部豪斯沼泽溪的桉树种群的身份在过去35年里一直没有得到解决。尽管有几名工作人员在这段时间里检查了遗址和生长在那里的树木,但对其分类地位几乎没有达成共识。人们提出了各种各样的建议,认为该实体是一个与dalrympleana, E. viminalis或E. bridgesiana有亲缘关系的新种,并且一度使用了未发表的手稿名称E. ' wollemiensis '。由于种群规模较小,受到野火和其他因素的威胁,实体短语E. sp. Howes Swamp Creek (M.Doherty 26)在联邦和州的濒危物种立法中被列为濒危分类群。在过去的几年里,我们通过田间、苗木和植物标本室的研究,确定了最初的参考标本是E. bridgesiana,而收集标本的种群是E. bridgesiana和E. viminalis的杂交群体。这两个亲本物种都存在于该地点,尽管前者在那里似乎非常罕见。我们建议将E. sp. Howes Swamp Creek从濒危物种立法中删除,并将E. sp. Howes Swamp Creek (M.Doherty 26)和E. ' wollemiensis ' ms作为E. bridgesiana的命名同义词。

Lepidosperma prospectum G.T.Plunkett & R.L.Barrett (Cyperaceae tribe Schoeneae) is here described as a new species in the Sydney region of New South Wales. It is highly restricted in distribution, occurring at Manly (Sydney Harbour National Park), Kamay Botany Bay National Park and Royal National Park in dense coastal shrublands behind coastal cliffs. These locations are within the traditional lands of the Gamaragal, Gweagal and Dharawal people respectively. Joseph Banks and Daniel Solander were the first Europeans to explore the flora of New South Wales in 1770 around Botany Bay but they did not collect this species. Lepidosperma prospectum is superficially similar to L. sieberi Kunth, which occurs in adjacent habitats, but molecular data have shown that it is more closely allied to Western Australian species. A brief review of recorded indigenous and European knowledge and utilisation of the genus Lepidosperma Labill. is presented to highlight the varied uses of the genus.
Lepidosperma prospectum G.T.Plunkett & R.L.Barrett是新南威尔士州悉尼地区的一个新种。它在分布上受到高度限制,发生在曼利(悉尼港国家公园),卡迈植物湾国家公园和皇家国家公园,在沿海悬崖后面密集的沿海灌木丛中。这些地点分别位于Gamaragal、Gweagal和Dharawal人的传统土地内。1770年,约瑟夫·班克斯和丹尼尔·索兰德是第一批探索新南威尔士州植物学湾周围植物群的欧洲人,但他们并没有收集到这种植物。Lepidosperma prospectum表面上类似于l . sieberi肯,这发生在相邻的栖息地,但分子数据表明,它是西澳大利亚的物种更加一致。乡土和欧洲对鳞片属植物的认识和利用综述。是为了突出该属的各种用途。

Seeds and indehiscent fruit of Anarthriaceae and Australian Restionaceae: a gallery of micromorphology 茴香科和茴香科的种子和不裂的果实:显微形态学的一个画廊

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.
aniconaceae和australrestionaceae的多孢子虫是种子或小坚果,通过扫描电子显微镜或多焦点显微镜显示,并考虑与先前发表的基于质体基因的系统发育有关。房裂型三眼蒴果是昆虫支系的基础,但不裂型果实经过多次进化。在澳大利亚的成员中,不开裂的果实在茴香科(Hopkinsia)中发现;石竹科:石竹科;Sporadanthoideae (Calorophus);细腕足亚科(Empodisma, Winifredia和整个细腕足和链足分支)。开裂果实的种子具有不同的表面纹饰,具有不同的表面图案,如Lyginia, Chordifex和Loxocarya等属。果皮在膜下呈膜质。在细爪猴支系中,从细爪猴支系的大部分是透明的,到亚历克乔吉亚和下坡木属的坚硬木质。在大多数桥枝属枝中,果皮是薄壁的,但在Catacolea中,果皮是木质的。不裂的果实大多脱落具花被片和花苞片附着或,在Baloskion和一些鳞翅目植物种,也具对生的颖片。种子重量取样不全面,从百松的0.08 mg到亚历克乔吉的>600 mg不等,大多数在0.3-3 mg[干重]范围内。种子重量较小的种子主要分布在降水较为可靠的多年生植物或因生长季节短而避免干旱的短命一年生植物中,但种子类型与生境之间的关系尚未得到研究。在昆士兰始新世-渐新世沉积物中,没有令人信服的证据表明化石分类群Restiocarpum和Milfordia花粉与Restionaceae有关。

Diagnostic features are illustrated, and distribution, habitat, and conservation status are discussed.","PeriodicalId":49440,"journal":{"name":"Telopea","volume":"12 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83584798","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}

Grevillea manglesii (Proteaceae: Grevilleoideae: Hakeinae) revisited 格雷维利亚manglesii (Proteaceae: Grevilleoideae: Hakeinae) revisited

The correct citation for Grevillea manglesii (Proteaceae) is G. manglesii Pépin (1838). A neotype is here selected from among historic collections, now at Paris (P). Should the minimal description provided by Pépin be successfully challenged as inadequate, the name would not change but the revised authority would be Grevillea manglesii (Graham) A.Baumann and N.Baumann (1843). The origins and complex taxonomic and horticultural history of G. manglesii and its synonyms Manglesia glabrata Lindl., Anadenia manglesii Graham, Grevillea manglesii Hort., Manglesia trilobata Hort. ex Ettingsh., and Manglesia cuneata Endl. are outlined and discussed, together with new insights discerned from James Mangles’ unpublished Letter Books. The important role of Captain James Mangles R.N. to the botany and horticulture of Grevillea manglesii is reviewed and historical errors are corrected. Manglesia glabrata Lindl. is lectotypified. G. ornithopoda Meisn. is reinstated at specific rank and G. dissectifolia (McGill.) Olde is published as a new combination. Both are phenetically diagnosable without intergrades and occur in discrete populations that sometimes overlap the distribution of related species.

A new rainforest tree species of the myrtle family (Myrtaceae), Syzygium nusatenggaraense Sunarti & Y.W.Low is described here based on two collections from the Lesser Sunda Islands. This species is superficially similar to Syzygium arcanum P.S.Ashton, a Bornean endemic tree species, but differs in a suite of morphological characters and geographic distribution. The new species is illustrated, and description is here given. Satu spesies pohon hutan hujan baru dari suku jambu-jambuan atau Myrtaceae, Syzygium nusatenggaraense Sunarti & Y.W.Low diterbitkan disini berdasarkan kepada dua koleksi dari Kepulauan Nusa Tenggara. Spesies ini mirip dengan satu spesies pohon endemik Borneo Syzygium arcanum P.S.Ashton, tetapi berbeda dalam rangkaian karakter morfologi dan distribusi geografisnya. Spesies baru tersebut diilustrasikan dan deskripsi diberikan di sini.
