The new, 5th edition of Flora of South Australia is published online in PDF-form. Today, the State Herbarium of South Australia released a first version of the chapter on the plant family Brassicaceae, describing the genus Lepidium.
Scarlett, N.H. & Hewson, H.J. (2019). Brassicaceae (partly) (version 1). In: Kellermann, J. (ed.), Flora of South Australia (ed. 5). 25 pp. (State Herbarium of South Australia: Adelaide). (8.6mb PDF).
Lepidium (peppercresses) is a cosmopolitan genus of around 220 species, of which 36 are endemic in Australia and 8 are introduced. Following recent molecular analyses, it now also includes Cardaria and Coronopus, which were formerly treated as distrinct genera. Neville Scarlett describes all 27 species that occur in South Australia in detail. Most species are illustrated with line-drawings and photographs.
The general link to the 5th edition of Flora of South Australiais flora.sa.gov.au/ed5, providing current treatments, glossary, introduction and cover pages for printing. Previous versions of Flora treatments are still available from our Superseded treatments page. Flora chapters are also available on Enviro Data SA and on this website under the “Flora of South Australia PDFs” link in the “Important Resources” listing.

Today, the State Herbarium of South Australia published Vol. 32 (2019) in the online version of Swainsona. This issue of the journal contains one large monograph on the lichens of Kangaroo Island:
Kantvilas, G. (2019). An annotated catalogue of the lichens of Kangaroo Island, South Australia.Swainsona 32: 1-97. (27.9mb PDF).
This magnum opus of Hobart-based lichenologist Gintaras Kantvilas, Head of the Tasmanian Herbarium, presents the results of over 10 years of work on the lichens of Kangaroo Island. During this time, the author undertook extensive fieldwork and reviewed more than 1500 herbarium specimens. The lichen flora of Kangaroo Island consists of 366 taxa, of which 14 are restricted to the island. Ninety-five species are reported for South Australia for the first time, of which 19 are also new records for Australia.
This landmark study is the first to thoroughly examine and document the lichens of the Kangaroo Island. Each species is listed with a short, diagnostic description, many are illustrated with photographs. All specimens used to compile the catalogue of lichens are listed, making this publication an invaluable tool for future research. A brief history of lichenological work on the island is included, as well as a description of the habitats that lichens occur in.
Hardcopy of this special issue “Lichens of Kangaroo Island” will be printed soon and should be available next month. More information on Dr Kantvilas’ project can also be found in a paper he wrote for the Proceedings of the Botany Symposium “Botany 2016 — Past, present and future“ (Swainsona 30: 17-24; 3.3mb PDF).

The Albany pitcher plant, Cephalotus follicularis was first described by the French botanist J.J.H. de Labillardiere from specimens collected by Leschenault de la Tour on Baudin‘s expedition to Australia. It had also been collected by Robert Brown during Flinder‘s voyage. The species is the only one in the genus Cephalotus (i.e. it is monotypic), which in turn is the only genus in the family Cephalotaceae (in the order Oxalidales), making it a truly remarkable species, not closely related to any other carnivorous plant.
“Cephalotus: The Albany pitcher plant” is the first comprehensive monograph on this unique species, featuring chapters on its botanical history, systematic and evolution, detailed botanical descriptions, illustrations and photographs, discussions of the plant’s morphology, ecology and genetics, as well as sections on conservation and cultivation of Cephalotus. The book is available from the publisher’s website.

Cephalotus is instantly recognisable for its distinctive and charismatic insect-trapping leaves. It is unique amongst carnivorous plants worldwide, being the only carnivorous plant in the rosid clade of flowering plants and the only monotypic family and genus of pitcher plants. Taking into account its extreme genetic and geographic isolation in the southwest of Western Australia, its pitcher leaves represent perhaps the most astounding example of convergent evolution amongst carnivorous plants, their toothed mouths and overarching lids being highly reminiscent of Nepenthes tropical pitcher plants and American pitcher plants alike. Cephalotus is extremely localised, surviving in only a fragment of its historic range as a result of habitat loss, disruption of natural ecological succession, and poaching.
Tonight, Lauren Black, one of the artists who were commissioned to produce artwork for the book, will give an “Artist Talk” about her watercolour of Cephalotus (unfortunately sold out). The line-drawings of Cephalotus were prepared by Alastair Robinson, who won the second price of the prestigious Margaret Flockton Award with his illustration, this year.

J.M. Bannister & J.G. Conran, Comparative leaf morphology and cuticular anatomy of Akania bidwillii (Akaniaceae) (6.7mb PDF)
The authors publish an illustrated description of the leaves of the monotypic genus Akania, which is endemic to eastern Australia. Together with the the genus Bretschneidera from China, Vietnam and India, which is also monotypic, it forms the small family Akaniaceae.
KeyBase is a database and web application for managing and deploying interactive pathway keys. It presents traditional dichotomous keys in a new way online. In addition to standalone keys, KeyBase also delivers identification keys to the new online Flora of Australia and VicFlora.
Keys to the South Australian Flora are currently being added to Keybase. Last week, Kat Ticli from the State Herbarium completed the conversion of the keys to species in Grasses of South Australia and uploaded them to KeyBase. Poaceae is one of the largest plant families in the State. Having this key and others online will enable easy access to this information and be helpful to anyone wanting to identify the native and naturalised grasses of South Australia.
