Champia Desvaux is a relatively well-demarcated genus in the family Champiaceae (Rhodymeniales). Its distinctive morphology includes hollow branches that are segmented by one-cell thick internal diaphragms, often with slight constrictions at the level of the diaphragms, giving the thallus a wormlike appearance. Aside from the diaphragms, the only other internal structures in the vegetative thalli are longitudinal filaments that bear lateral vesicular cells. Depending on the species, the longitudinal filaments can be distributed through the internal cavity or be restricted to the periphery, in which case they line the inner surface of the cortex.

The small, endemic Western Australian genus Stachystemon Planch. (Euphorbiaceae: Caletieae: Pseudanthinae) was last revised by Halford and Henderson (2003) at which time nine species were recognised. Stachystemon exilis Hislop & R.W.Davis, a new and uncommon species from the Swan Coastal Plain described below, is the first to be published since that treatment. Although the earliest collections of this species were made before the revision was completed, it appears that its authors had no opportunity to examine this material during the course of their studies.

Ongoing taxonomic revisions in Tephrosia Pers. (Fabaceae: Millettieae) Australia-wide are continuing to identify putatively new and patently novel taxa, especially from areas in which there have been few, if any, systematic surveys. While some of these taxa are part of difficult complexes containing a number of described and phrase-named taxa as well as variant forms within each, others are readily recognisable and seemingly without close affinity in the Australian flora; the new species described herein is one such distinctive species. The name T. sp. Saw Ranges (D. Kabay s.n. PERTH 06720544) was added to Western Australia’s vascular plant census in 2011, based on a single fruiting and seeding specimen that could not be matched to any known taxon in Western Australia or the Northern Territory (I. Cowie pers. comm. 2011). Over the past seven years a handful of additional specimens, usually in fruit but occasionally possessing flowers, have been submitted to the Western Australian Herbarium (PERTH) or uncovered at the Northern Territory Herbarium (DNA), validating the distinctness of this species and finally allowing it to be described in full.
正在进行的毛茛分类修订。在全澳大利亚范围内,人们正在继续发现新的和明显新颖的分类群,特别是在那些很少(如果有的话)系统调查的地区。虽然这些分类群中的一些是复杂复合体的一部分,其中包含许多已描述和短语命名的分类群,以及每个分类群中的变体形式,但其他分类群很容易识别,似乎在澳大利亚植物区系中没有密切的亲缘关系;这里所描述的新种就是这样一种独特的物种。T. sp. Saw Ranges (D. Kabay s.n. PERTH 06720544)这个名字在2011年被添加到西澳大利亚的维管植物普查中,基于一个单一的结果和种子标本,该标本无法与西澳大利亚或北领地的任何已知分类群相匹配。通讯,2011)。在过去的七年里,一些额外的标本,通常是果实,偶尔有花,已经提交给西澳大利亚植物标本馆(珀斯)或在北领地植物标本馆(DNA)发现,证实了这个物种的独特性,并最终允许对其进行完整的描述。

A new species of Hibiscus L. (Malvaceae) is described below as part of a large revision of the Australian components of H. sect. Bombicella DC. Restricted to Katjarra (the Carnarvon Range), part of the Birriliburu Indigenous Protected Area some 160 km north-north-west of Wiluna, this species was first collected in 1998 but only recognised as distinctive in 2012 when it was added to Western Australia’s vascular plant census under the name H. sp. Carnarvon (S. van Leeuwen 5110) by Johan Hurter (Parker & Biggs 2013). It was subsequently recollected during regional surveys in August 2012 and May 2013 by Gibson et al. (2014), who astutely collected ample herbarium samples along with detailed habitat notes and photographs. Examination of this material, along with specimens from all Australian members of sect. Bombicella, has confirmed that it is morphologically distinct, with its novel status further supported by a preliminary molecular phylogeny of the Australian Hibiscus (McLay, in prep.).
木槿L. (malvacae)的一个新种被描述如下,作为H. sect. Bombicella DC的澳大利亚组分的大修订的一部分。该物种局限于Katjarra (Carnarvon山脉),是Birriliburu土著保护区的一部分,位于Wiluna西北约160公里处,该物种于1998年首次被采集,但直到2012年才被约翰·赫特(Parker & Biggs 2013)以H. sp. Carnarvon (S. van Leeuwen 5110)的名字添加到西澳大利亚维管植物普查中,才被认为是独特的。随后,Gibson等人(2014)在2012年8月和2013年5月的区域调查中收集了大量植物标本,并收集了详细的栖息地笔记和照片。对这些材料以及来自Bombicella组所有澳大利亚成员的标本的检查证实,它在形态上是独特的,澳大利亚木芙蓉的初步分子系统发育进一步支持了它的新地位(McLay, in prep.)。

Myxomycetes (slime moulds) are a diverse group of c. 1,000 species of amoeboid eukaryotes (Lado 2005–2019). They are common in the soil and on decaying vegetable matter such as wood and leaf litter, although it may be difficult to detect these organisms due to their diminutive size (often less than 1 mm high) and dependence on conducive seasonal conditions for sporulation. Hence, while new species are sometimes discovered in the field, they are more often found through the use of what is termed the moist chamber culture. When conditions are unfavourable for continued growth, macroscopic fruiting bodies that contain spores are formed. Prior to this, myxomycetes exist in a vegetative phase as a plasmodium—a giant, multi-nucleate amoeba formed from the merging of two compatible freeliving myxoflagellates or myxamoebae cells from germinating spores.

The new species of Myrtaceae tribe Chamelaucieae DC. that is described below is very distinctive, having a mass of long projections on the outside of its flowers and densely papillose-warty stems. It was discovered in October 1952 by Charles Gardner, who assigned the manuscript name Baeckea moschata C.A.Gardner to his collection and made five sketches of the highly ornate flowers (on PERTH 06796532). However, overwhelmed by the large number of unnamed species known at that time, Gardner never formally published this species, which later became known as B. sp. Three Springs (M.E. Trudgen 5368).

Lechenaultia R.Br. (Goodeniaceae) is a charismatic genus of 29 formally named species, of which all but one occur in Western Australia (Western Australian Herbarium 1998–; CHAH 2006). Many produce showy flowers in striking shades of blue, red, orange or yellow making them a popular choice for native gardens. Indeed, the genus has a long horticultural history, first appearing in the glasshouses of Victorian England with the introduction of L. formosa R.Br. to the United Kingdom in 1824 (Step 1897). Even Charles Darwin was fascinated by Lechenaultia, conducting experiments over successive years to understand the pollination mechanism of the unusual cup-like indusium that distinguishes the family Goodeniaceae (Darwin 1861, 1871). Unfortunately, while some species are well known in cultivation many are scarce in the wild, with L. chlorantha F.Muell. listed as Endangered, L. laricina Lindl. as Vulnerable, and a further 11 otherwise considered rare or poorly known (Western Australian Herbarium 1998–; Smith & Jones 2018). The new species described below is one such plant—discovered by William Archer in the Mallee bioregion of southern Western Australia in 2012, only three populations occurring in close proximity have been discovered to date. This species also has horticultural potential as it produces highly attractive, mauve-blue flowers that fancifully resemble a flamenco dancer.
