(1) Y. Pillon, D. Craynb, S.J.R. Streiff & J.M. de Vos, A suprageneric classification of Oxalidales (200kb PDF).

Using the results of recently published thoroughly-samples phylogenies, the authors from Australia, France and Switzerland, publish a revised classification of the order Oxalidales, which contains the plant families Brunelliaceae, Cephalotaceae, Connaraceae, Cunoniaceae, Elaeocarpaceae (incl. the former Tremandraceae) and Oxalidaceae. Some of these families are well-represented in Australia. One new suborder, five new subfamilies, and three new tribes are described.

(2) G. Kantvilas, Tasmanian additions to the genus Inoderma (Arthoniaceae) (3.2mb PDF).

The author from the Tasmanian Herbarium reviews the lichen genus Inoderma, which was split recently from Arthonia, and accepts two species for Australia: one described as new, the other an existing species that is transferred to Inoderma. In total, the genus now has seven species worldwide. A species of fungus that grows on Inoderma lichens is also reported: Chaenothecopsis brevipes.

The International Botanical Congress – Madrid July 2024

International Botanical Congress – Madrid 2024

The 20th International Botanical Congress (IBC 2024) has begun in Madrid (Spain) with the Nomenclature Section (15–19 July 2024) followed by the Congress (21–27 July 2024).  This global congress takes place every six years under the supervision of the International Association for Botanical and Mycological Societies (IABMS). Originally the 20th congress was going to take place in 2023 in Brazil after Shenzhen’s (China) 2017. The impact of the worldwide pandemic meant that the meeting could not be held in Brazil in 2023.

The congress includes plenary lectures, concurrent symposia, posters, exhibitors, short courses and workshops. The modern incarnation of the congress is an integrated forum for knowledge on the plant and mycological world.

Several poster presentations are being given by State Herbarium of South Australia PhD students Andrew McDougall and Luis Williamson at the IBC (for more information about the IBC program go to the conference website). They will update us on their experience attending this meeting at the congress and we wish them the best of luck for their presentations and in meeting the worlds botanical community.

More information about the students presenting and their work is available here: https://know.ourplants.org/current-research_ibc_madrid/

In a few weeks the International Mycological Congress is being held in The Netherlands. We update you closer to the date.

The authors review Hibbertia cunninghamii and four related species, H. amplexicaulis, H. nymphaea, H. perfoliata and H. porongurupensis, all endemic to south-western WA and are characterised by amplexicaul leaf bases. The circumscriptions of the species is clarified and a revised identification key published. All species are illustrated with colour photographs.

T.A. Hammer, New combinations in the Hibbertia vestita (Dilleniaceae) species group from New South Wales (15.4mb PDF).

The author presents evidence that two subspecies of Hibbertia from New South Wales are better treated at species level. He changes the names of Hibbertia ericifolia subsp. acutifolia to the species H. acutifolia, and H. florida subsp. angustinervis to H. angustinervis. A table outlining the differences is provided and detailed photographs of leaves and flowers show the morphologies of the species and how they differ from typical Hibbertia ericifolia and H. florida.

The authors report on the history of the natural history collections of the Gulliver siblings, who were active in the late 1800s. After a short biography of the family, they discuss the different periods in their lives: Thomas and Benjamin Gulliver provided plant and animal specimens for Museums and Herbaria. Their sister Susannah collected plants at a more limited scale.

The main focus of the article is the plant collections from New South Wales, Tasmania, the Northern Territory and Queensland, which are now mainly found at the National Herbarium of Victoria (MEL) and the Royal Botanic Gardens, Kew (K), with lesser numbers at other institutions. Lectotypes are chosen for some names that were published from Gulliver collections.
