Desmids associated with Sphagnum L. from terrestrial and aquatic habitats were investigated in the New England Tableland Bioregion. Descriptions and figures for 80 taxa are presented herein, nine of which are newly recorded for Australia, and a further seven are newly recorded for New South Wales. Two novel species of desmid, Micrasterias bicoronata A.Kenins and Cosmarium phymatodeum A.Kenins, are described. The floristic composition of desmids at Basket Swamp and Ebor Common, were compared to assess their conservation value based on an existing and modified scheme better suited to desmids from Australia. Basket Swamp received a relatively high score based on greater species richness and numerous endemics present. In contrast, Ebor Common scored lower due to less diversity and few regionally endemic species. This study also highlights that the desmid community found amongst Sphagnum in Australia is highly diverse (βSOR = 0.82) and can differ markedly among the four assessed sites due to spatial turnover (βRATIO = 0.15). While there are species in common with the much more extensively studied Sphagnum habitats in central and western Europe, Australia has its own distinctive desmid floral elements.
研究了新英格兰高原生物区水陆栖和陆生生境中与Sphagnum L.有亲缘关系的小鼠类。本文介绍了80个分类群的描述和数据,其中9个是澳大利亚新记录的,另外7个是新南威尔士州新记录的。本文报道了两种新种双冠小锥虫(Micrasterias bicoronata A.Kenins)和藻质小锥虫(Cosmarium phymatodeum A.Kenins)。采用一种更适合于澳大利亚地脉菊的改良方案,对篮子沼泽地脉菊和Ebor Common地脉菊的区系组成进行了比较,以评估其保护价值。篮子沼泽获得了相对较高的分数,基于更大的物种丰富度和大量的地方性植物。相比之下,Ebor Common由于多样性较少和区域特有物种较少而得分较低。该研究还强调了澳大利亚Sphagnum中发现的desmid群落具有高度多样性(β比值比= 0.82),并且由于空间转换(β比值比= 0.15),在四个评估地点之间可能存在显著差异。虽然在中欧和西欧有一些物种与广泛研究的泥鳅栖息地相似,但澳大利亚有自己独特的泥鳅花元素。

The Utricularia lasiocaulis F.Muell. complex (subg. Polypompholyx; sect. Lasiocaules) is a morphologically and ecologically variable group of closely related taxa with a mostly tropical distribution across northern Australia. A recent molecular phylogenetic study placed the recognised species U. kamienskii F.Muell. sister to a clade of accessions relegated to either U. leptorhyncha O. Schwarz or U. lasiocaulis, with the latter previously circumscribed as an assemblage of highly variable morphological forms. We have expanded the previous study to include populations representing the known distributions of all three species and have attempted to include all morphological variants; 55 ingroup accessions were used in the full phylogenetic analysis based on two non-coding chloroplast regions (rps16, trnD–T) and the nuclear ribosomal internal transcribed spacer (ITS). We found that the pink corolla form of the usually white flowered U. kamienskii is not sufficiently different, and we retain it under that species. We also found strong support for a paraphyletic U. leptorhyncha, with the smaller flowered accessions matching the type material placed sister to all other U. lasiocaulis forms, including a grouping previously assigned as a larger flowered U. leptorhyncha. Within the U. lasiocaulis clade we found that much of the variation sorts into well-supported clades that we find are sufficiently morphologically and genetically differentiated from the type clade for recognition at the specific rank, namely Utricularia brennanii R.W.Jobson & Baleeiro from Northern Territory and Queensland, Utricularia cowiei R.W.Jobson & Baleeiro from the Kimberley region of Western Australia, and U. disjuncta R.W.Jobson & Baleeiro restricted to the Darwin and Gulf region of the Northern Territory.
水蛭属植物。复杂(subg。Polypompholyx;是一个形态和生态变化密切相关的分类群,主要分布在澳大利亚北部的热带地区。最近的一项分子系统发育研究将公认的物种U. kamienskii F.Muell。隶属于U. leptorhyncha O. Schwarz或U. lasiocaulis的一个分支的姐妹,后者先前被限定为高度可变形态的组合。我们扩大了先前的研究,包括代表所有三种已知分布的种群,并试图包括所有形态变异;基于rps16、trnD-T两个非编码叶绿体区域和核糖体内部转录间隔区(ITS),对55个组内材料进行了系统发育分析。我们发现,通常开白色花的卡米恩斯基的粉红色花冠形态差异不大,我们将其保留在该物种下。此外,我们还发现了一个全葡萄型的leptorhyncha,其中较小的花品种与所有其他U. lasiocaulis的姊妹型材料相匹配,包括一个先前被指定为较大花的U. leptorhyncha的类群。在U. lasiocaulis分支中,我们发现许多变异分类为支持良好的分支,我们发现这些分支在形态和遗传上与类型分支有足够的区别,可以在特定的等级上识别,即北领地和昆士兰的Utricularia brennanii R.W.Jobson & Baleeiro,西澳大利亚金伯利地区的Utricularia cowiei R.W.Jobson & Baleeiro,和美国分离的r.w.约翰逊和巴莱罗仅限于北领地的达尔文和海湾地区。

Caloglossa fluviatilis is one of the least known freshwater algal species of its genus, having been reported from its type locality in Pedro Miguel, Republic of Panama, and Chalakkudy and Periyar Rivers in the State of Kerala, India. This study presents a new locality record of the species from Bataan province on the island of Luzon, Philippines. C. fluviatilis is characterised by having (1) a thallus having a width at the internode region narrower than 1.0 mm, (2) moderate development of adventitious secondary branches at the node, and (3) fewer than eight rhizoidal filaments arising from pericentral cells at the node. Indeed, this Philippine population of C. fluviatilis has helped fill the gaps and extended the distribution of the species to the western Pacific region. Further studies and reassessment of freshwater Caloglossa specimens will contribute to further understanding of these little-known genus members.        
Caloglossa fluviatilis是其属中最不为人所知的淡水藻类之一,据报道,在巴拿马共和国佩德罗米格尔河和印度喀拉拉邦的Chalakkudy河和Periyar河的模式地点发现了它。本文报道了一种来自菲律宾吕宋岛巴丹省的新的地方性记录。川菜的特点是:(1)节间区域的菌体宽度小于1.0毫米,(2)节处的不定次枝发育适中,(3)节处中心周围细胞产生的根状细丝少于8根。事实上,菲律宾的河豚C. fluviatilis种群帮助填补了空白,并将该物种的分布扩展到西太平洋地区。对淡水Caloglossa标本的进一步研究和重新评估将有助于进一步了解这些鲜为人知的属成员。

Four species are added to the Grevillea thelemanniana Group, the constituency of which is discussed in light of recent phylogenetic analyses. Two new species are described. Grevillea cooljarloo Keighery and Olde was previously included by some in Grevillea preissii Meisn. subsp. preissii or as G. pinaster divided-leaf form, and is presently known informally as Grevillea thelemanniana subsp. Cooljarloo (B.J. Keighery 28B) by the Western Australian Herbarium. Grevillea gillingarra Olde and Keighery has previously been confused with G. thelemanniana Hügel ex Endl. Grevillea preissii subsp. glabrilimba Olde and Marriott is here recognised at specific rank, as G. glabrilimba (Olde and Marriott) Olde. Grevillea preissii is more narrowly circumscribed, in line with the original concept sensu Meisner (1845), without subspecies. A photo of the Blaschka glass model of Grevillea preissii is included with permission. The historical confusion between G. thelemanniana and G. preissii is revisited. Grevillea variifolia subsp. bundera Keighery is recognised at species-level as G. bundera (Keighery) Olde and Keighery. A conservation assessment for all taxa is provided and a key to the revised Thelemanniana Group, as currently accepted, is supplied.

Grevillea tesselata Olde is described here as a new species from south-west Western Australia, known only from a small population in a fragmented roadside landscape, and previously recognised under the phrase name Grevillea sp. Trayning (W. Johnston WJ 071). Following the Flora of Australia, the new species keys to the Grevillea Acacioides Group which comprises only three species, G. endlicheriana Meisn., G. acacioides C.A.Gardner ex McGill. and G. gordoniana C.A.Gardner. A binary assessment of 50 morphological characters presented here supports the view that G. acacioides and G. endlicheriana are sister species. A key to the new species is provided and its distribution updated. Grevillea tesselata has a Priority One Conservation Code according to the Western Australian Herbarium.

We describe two new species of Prasophyllinae from New South Wales, in the genus Genoplesium R.Br. following the generic classification currently in use at the National Herbarium of New South Wales. One of these new species, Genoplesium branwhiteorum M.A.M.Renner & P.H.Weston, which we name for the Branwhite family, has been known for nearly a decade under the informal name Corunastylis sp. Charmhaven (NSW896673). The other new species, G. geminatum M.A.M.Renner & Towle has been confused with both G. rufum (R.Br.) D.L.Jones & M.A.Clem. and G. trifidum (Rupp) M.A.M.Renner, although it is more similar to G. mucronatum (Rupp) M.A.M.Renner and G. tasmanicum D.L.Jones, and possesses a combination of features of consistent expression supporting its recognition as a new species. Three new combinations are made. Genoplesium cuspidatum (D.L.Jones & L.M.Copel.) M.A.M.Renner, comb. nov. is based on Corunastylis cuspidata D.L.Jones & L.M.Copel., Genoplesium laminatum (Fitzg.) M.A.M.Renner, is based on Prasophyllum laminatum Fitzg. and Genoplesium mucronatum (Rupp) M.A.M.Renner is based on Prasophyllum mucronatum Rupp. [listed as a synonym of G. rufum in PlantNet].
本文报道了来自新南威尔士州的二新种,属genplesium R.Br。按照新南威尔士州国家植物标本馆目前使用的一般分类。其中一个新物种,genplesium branwhiteorum M.A.M.Renner & P.H.Weston,我们将其命名为Branwhite家族,它在近十年来一直以非正式名称Corunastylis sp. Charmhaven (NSW896673)为人所知。另一个新物种G. geminatum M.A.M.Renner & Towle与G. rufum (r.b.r。d.l.琼斯和M.A.Clem。和G. trifidum (Rupp) M.A.M.Renner,尽管它与G. mucronatum (Rupp) M.A.M.Renner和G. tasmanicum D.L.Jones更相似,并且具有一致表达的特征组合,支持其作为新种的识别。形成了三种新的组合。虎杖草(D.L.Jones & L.M.Copel)M.A.M.Renner,梳子。《十一月》是基于Corunastylis cuspidata D.L.Jones & L.M.Copel。;;;;;;;M.A.M.Renner,是基于prophyllum laminatum Fitzg。而紫叶甘蓝(genplesium mucronatum, Rupp) M.A.M.Renner是基于紫叶甘蓝(Prasophyllum mucronatum Rupp)。[在PlantNet中被列为G. rufum的同义词]。
