A new species, Indigofera centralis Peter G. Wilson & Rowe, is described from Central Australia, west of the Finke Gorge National Park in the Northern Territory; it resembles some other inland species (I. fractiflexa, I. gilesii, I. warburtonensis and I. helmsii) but differs most conspicuously by the relatively larger flowers.
一个新种，Indigofera centralis Peter G. Wilson & Rowe，被描述来自澳大利亚中部，北领地芬克峡谷国家公园以西;它类似于其他一些内陆物种(I. fractiflexa, I. gilesii, I. warburtonensis和I. helmsii)，但最明显的区别是相对较大的花。

Three species are recognised in a new circumscription of the genus Chaetospora R.Br. Chaetospora is lectotypified on C. curvifolia R.Br. A new combination, Chaetospora subbulbosa (Benth.) K.L.Wilson & R.L.Barrett is made for Schoenus subbulbosus Benth. Lectotypes are also selected for Chaetospora aurata Nees, Chaetospora curvifolia R.Br., Chaetospora turbinata R.Br., Elynanthus capitatus Nees, Schoenus subbulbosus Benth., Schoenus subg. Pseudomesomelaena Kuk. and Schoenus sect. Sphaerocephali Benth. Two species are endemic to south-western Australia, while the third is endemic to south-eastern Australia. Full descriptions, illustrations and a key to species are provided. All species have anatomy indicative of C3 photosynthetic-type.

Two additional species in the Indigofera haplophylla are described. Indigofera brennanii Peter G. Wilson, is a recently discovered taxon that occurs on Groote Eylandt and in Limmen National Park on the adjacent mainland. Indigofera fimbriolata Peter G. Wilson is a geographically isolated species that occurs in Bulleringa National Park, Queensland; it was formerly included in I. rupicola. Although both taxa are found in national parks, their conservation status has not been assessed.

Cryptic bryophyte species exhibit a decoupling in the degree of morphological and molecular divergence, as a result of different processes, from recent divergence to stasis. Here a body of cryptic species literature comprising 110 papers published between 2000 and end 2018 is reviewed. Most studies of cryptic species focused on northern hemispheric taxa, but we do not yet have sufficient studies to assess whether a geographic bias in the distribution of cryptic species exists, and we don’t know how many cryptic bryophyte species there might be globally. Fully two-thirds of all studies on cryptic bryophyte species rested their claims of morphological crypsis on previous taxonomic investigations, without revision of morphology to confirm cryptic species status. There is more than one kind of morphological crypsis, and while quantification of morphological patterns can contribute to our understanding of crypsis this is a widely neglected component. The usage of ‘cryptic species’ as an etymological tool to flag instances where traditional species concepts are deficient devalues the term, and a distinction between genuine crypsis and business as usual revision of species circumscription should be re-established and maintained. Hybridisation is possibly an under-appreciated contributor to cryptic species, but inference of hybridization has been limited by study design. Opportunities exist in the application of geometric morphometric methods and next generation sequencing technologies to overcome intrinsic limitations in traditional morphological and molecular data sources.

Phylogenetic studies have shown that Cayratia Juss is not monophyletic. Cayratia s.str. is now confined to those species with a U-shaped endosperm rather than a T-shaped endosperm. The latter are now in three genera Causonis Raf., Pseudocayratia J. Wen, L.M. Lu & Z.D. Chen, together with an undescribed African genus. As a result, new combinations are required for three species occurring in Australia: Causonis clematidea (F. Muell.) Jackes, C. eurynema (B.L.Burtt) Jackes and C. maritima (Jackes) Jackes. Cayratia japonica (Thunb.) Gagnep., and Cayratia trifolia (L.) Domin, have been transferred to Causonis, as Causonis japonica (Thunb.) Raf., and Causonis trifolia (L.) Mabb. & J. Wen.

Eucalyptus calidissima (Myrtaceae), a new and highly restricted ironbark species from the Hunter Valley of New South Wales is described and illustrated. The new species had previously been included in E. nubilis Maiden & Blakely (syn. Eucalyptus nubila L.A.S.Johnson, orth. var.), but differs in the ribbed hypanthia, hemispherical to bluntly-conical calyptra which are shorter than the hypanthia, and the slightly larger, globular to obconical ribbed fruit. At present, E. calidissima is known only from a single population occurring across c. 200 ha and is considered rare, but it is not under immediate threat. Amendments to relevant sections of the New South Wales and Australian identification keys are provided.

Across tropical northern Australia 14 Drosera species are recognised within the D. petiolaris complex. The complex is placed in section Lasiocephala; a group of perennial sundews mostly characterised by an indumentum of white hairs upon the petiole. Here we describe a new species for the complex, D. stipularis Baleeiro, R.W.Jobson & R.L.Barrett, which is known only from white-sand habitats on Cape York Peninsula, Queensland. The new species is allied to D. petiolaris R.Br. ex DC. and D. lanata K.Kondo.

Australia has seven species in Utricularia L. section Utricularia, with the habit for all members of either affixed or suspended aquatic. Of the six recognised Australian species, one is endemic, one is pantropical, three are also distributed across Asia or Papua New Guinea - with U. australis R.Br. extending into Europe, and one other, U. stellaris L.f. into Africa. We present a molecular phylogeny based on two plastid and the nuclear ITS sequences for members of the subgenus Utricularia representing U. aurea Lour. and closely allied species from across each of their distributions. The molecular phylogeny provides strong support for recognition of a new species Utricularia adamsii R.W.Jobson & Davies-Colley (Lentibulariaceae), here described as new member of section Utricularia. This taxon was previously included within U. aurea, however, our molecular phylogeny and morphology supports a sister relationship with U. muelleri Kamienski. We provide a revised concept of U. aurea, and a description of the new species. The morphological differences between U. adamsii, U. muelleri, U. aurea and closely related species are here discussed, and an identification key provided. Distributions and habitat preferences of these taxa are discussed.
