Testing species delimitation in Acacia: are gidgee (A. cambagei) and Georgina gidgee (A. georginae) two distinct species?

Barbara Azevedo de Oliveira (The University of Queensland); Rod Fensham (The University of Queensland, Queensland Herbarium); Lyn Cook (The University of Queensland). Acacia cambagei R.T. Baker and A. georginae Bailey are dominant woody species found in the Australian arid zone, spanning from Queensland to the Northern Territory and into the north of South Australia. These species, commonly known

Systematic revision of Pedicularis L. (Orobanchaceae) for the Flora of Bhutan.

Rinchen Yangzom (University of New England)  Pedicularis, a charismatic genus of hemiparasitic plants in Orobanchaceae, predominantly thrives in the alpine and artic regions of the Northern Hemisphere. Bhutan is home to 69 taxa of Pedicularis, of about 800 species worldwide. Despite several taxonomic efforts a considerable number of Pedicularis taxa remain taxonomically unresolved and a significant portion of

Unearthing Agaricus down under: Exploring species boundaries in eastern Australasian Agaricus (Basidiomycota).

Amelia-Grace Boxshall (University of Melbourne, School of BioSciences); Joanne Birch (University of Melbourne, School of BioSciences); Jerry Cooper (Manaaki Whenua); Teresa Lebel (State Herbarium of South Australia). Agaricus is a large basidiomycete genus estimated to contain >500 species globally. However, Australasian Agaricus remain underrepresented in taxonomic revisions of the genus and their diversity remains incompletely understood. Until recently, only

Rethinking the systematics, evolution and biogeographic history of the mahogany family (Meliaceae).

Elizabeth M. Joyce (Ludwig-Maximilians-Universität München). Meliaceae is an economically valuable family of c. 740 species, with a high diversity of lifeforms and habitats throughout its predominantly pantropical distribution. Despite the economic and biological importance of the family, infra-familial relationships remain unclear. Further, recent fossil evidence brings the assumed African origin of the family into question. In

Biogeography of the only irises disjunct across the Pacific Ocean.

Sophie S. Newmarch (Massey University); Richard C. Winkworth (Massey University); Dan J. Blanchon (Auckland War Memorial Museum); Joanne L. Birch (University of Melbourne); Nicolás García (Universidad de Chile); Jennifer A. Tate (Massey University). Taxa with disjunct distributions have long fascinated biologists and have provided important insights into biological evolution in the southern hemisphere. Libertia and Orthrosanthus are two understudied

Can the relationships of speargrasses/taramea (Aciphylla; Apiaceae) be resolved with ddRADseq?

Lara Shepherd (Museum of New Zealand Te Papa Tongarewa); Leon Perrie (Museum of New Zealand Te Papa Tongarewa). Aciphylla is a genus of plants in the carrot family with a huge diversity of forms, ranging from tiny, soft-leaved herbs, to large spiky mounds a few metres across with huge, pointed clusters of flowers. Aciphylla comprises ~42 species, two of

Resolving species complexes among taramea, speargrasses, Aciphylla (Apiaceae) using ddRADseq.

Leon Perrie (Museum of New Zealand Te Papa Tongarewa); Lara Shepherd (Museum of New Zealand Te Papa Tongarewa). The 40 species of Aciphylla endemic to New Zealand make it one of the country’s biggest indigenous genera.  In the Apiaceae, the colloquial name of speargrasses reflects that the leaflets of most species have sharp, stiff, skin-piercing apices with the

Mycorrhizal associations: biotic correlates of phylogenetic dispersion patterns in the Sunshine Coast Heathlands, Queensland, Australia?

Hilary R. Pearl (University of the Sunshine Coast); Alison Shapcott (University of the Sunshine Coast). This study provides the first overview of mycorrhizal functional groups in Queensland Sunshine Coast heathlands, a community of low phylogenetic diversity. Broad proportions of mycorrhizal functional groups in the heathlands were compared with patterns in the surrounding rainforest flora, and across
