Danhatchia novaehollandiae D.L.Jones & M.A.Clem. and D. australis (Hatch) Garay & Christenson were separated at species rank due to differences in petal length and flower opening, with the Australian species having smaller, tardily opening flowers. From this, flower lengths for Australia and New Zealand are expected to be bi-modally distributed with peaks at c. 3 mm and c. 5 mm respectively. Flowers on all available herbarium specimens in AK, CANB, and NSW were measured, and flower length was found to be unimodal, with nearly identical ranges in Australian and New Zealand plants. Flower size variation in Australian and New Zealand Danhatchia specimens has two significant contributing components, inter-individual variation, and ontogenetic variation where flowers increase in size as they age. Dimensions previously recorded for the two species reflect upper and lower limits on the range of variation in flower size present in both New Zealand and Australia, respectively. Within herbarium material, 20% of flowers on New Zealand specimens, and 40% of flowers on Australian specimens exhibited signs of opening. There was no correlation between flower size and opening, as might be expected if the two species were both present in Australia and/or New Zealand. Neither the biogeographic context, pollination system, nor morphological evidence support Danhatchia australis and D. novaehollandiae as distinct species.

Dodonaea crucifolia I.Telford & J.J.Bruhl (Sapindaceae, Dodonaeoideae), endemic to north-eastern New South Wales, Australia, and previously confused with D. hirsuta (Maiden & Betche) Maiden & Betche, is described as new. Dodonaea hirsuta is recircumscribed with the D. crucifolia components removed and with male flowers described for the first time. The distribution, habitat, and conservation status of both species are discussed and a table is provided comparing selected morphological attributes. Images of the new species and D. hirsuta are provided. The identification keys in Flora of Australia and NSW FloraOnline are modified to include the new species.

Orthographic errors in the specific epithets of Porella cranfordi Steph. and Temnoma townrowii R.M.Schust. are corrected. The orthography of the specific epithet of Pyrrhobryum paramattense (Mull.Hal.) Manuel is discussed, and the original spelling is retained. The collector of the type of Pyrrhobryum paramattense was most likely Franz Wilhelm Sieber, not Charles von Hugel.

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.
