This month, Australian Post released a new set of three stamps about seed banking in Australia. The stamps feature seeds of rare and threatened Australian plants:

• Rytidosperma clelandii, a rare perennial grass from South Australia; it is named after naturalist Sir J.B. Cleland, who was instrumental in establishing some of the State’s first conservation parks
• Epacris petrophila, a near-threatened alpine shrub from the Australian Alps and high-altitude areas in Victoria and Tasmania
• Petrophile latericola, an endangered shrub from Western Australia.

The seed image of the South Australian species were provided by the South Australian Seed Conservation Centre at the Botanic Gardens and State Herbarium. The Seed Centre collects seeds from regions across the state to safeguard them in long term storage at sub-zero temperatures. By 2020, the centre aims to have at least 90 per cent of SA’s threatened plant species in the seedbank. The Australian Seed Bank Partnership facilitates and coordinates the activities of the country’s seedbanks.

Details on the individual stamps and an article on seed conservation can be found on the Australia Post website.

The 2019 Queen’s Birthday Honours list included two names with a close relationship to the State Herbarium of South Australia: Bev Overton and Peter Copley. Bev received the award of Member of the Order of Australia, and Peter received the award of Public Service Medal.

Back in February 2016, the State Herbarium did a blog article on Kangaroo Island couple Bev and Dean Overton. The story congratulated them for being recognised as Kangaroo Island high achievers for their outstanding efforts in conserving and raising awareness of KI’s natural environment at the Local Achievers Natural Resource Management Board Awards ceremony held on Australia Day that year.

Last year the Herbarium was approached by Kangaroo Island environmental consultant and botanist Michelle Haby to help support a nomination for Bev Overton to receive recognition in the 2019 Queen’s Birthday Honours. The final nomination was put together and submitted by Michelle and Bev’s husband Dean. Sadly Dean died unexpectedly before the news of Bev’s successful nomination was known.

Peter’s medal recognises his contribution and commitment of more than 40 years to help conserve threatened species and ecological communities in South Australia, as well as his role in biodiversity research and policy development. Peter reviewed the daisy genus Ixodia for his Honours at the University of Adelaide and has contributed 3601 collections to the State Herbarium over the years. His interest in botany was no doubt inspired by his father Bruce Copley, a Yorke Peninsula farmer who pursued an interest in his local native flora by collecting and submitting many specimens to the Herbarium.

Manager Peter Canty and Senior Botanist Peter Lang have worked closely together with Peter over many of those years, especially when they were part of the Biological Survey of South Australia program. Peter Copley lead the over decade-long biological survey of the Anangu Pitjantjatjara Yankunytjatjara Lands. The knowledge captured by that survey was greatly enhanced by working with Aboriginal Traditional Owners and Peter’s ability to establish close working relationships with the elders and their communities was pivotal in this particular survey’s success, and being recognised with a SA Great Award in 2003 in the Environment Category for an ‘Outstanding Contribution to South Australia’.

The Herbarium was very pleased to be involved in their nominations and wishes to congratulate them on their well-deserved recognition.

Recently, Chief Botanist, Prof. Michelle Waycott, was interviewed by The Adelaide Review about the history of the State Herbarium of South Australia and its holdings. The resulting article is now available.

As mentioned in the article, during South Australia’s History Festival, the State Herbarium will also offer guided tours through the old Tram Barn building. Please note that the dates in the above articles are not correct. The tours will take place on Sat., 25 May & Sun., 26 May 2019.

Please go to the History Festival’s website for more information.

The State Herbarium also published the following brochures, which are accessible online:

• Canty, P. (2012). The old tram barn: A short history of the Tram Barn A, now housing the State Herbarium of South Australia. (1.1mb PDF)
• Bell, G. (2012). One million and counting: History and special collections of the State Herbarium of South Australia. (0.5mb PDF).

Two scientists from the State Herbarium of South Australia have recently collaborated with colleagues to produce research papers that were published in well-known Nature Research journals during the last week.

Hon. Research Associate Pam Catcheside is among 62 authors, collaborating in this global effort to produce a phylogeny of 5,284 species of Agaricomycetes. These mushroom-forming fungi have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfill diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. This ground-breaking, first comprehensive phylogeny of mushroom-forming fungi reveals large-scale patterns of their evolutionary history.

Some years ago, State Herbarium botanist Jürgen Kellermann was contacted by Jesse Kalwij (now working in Germany) to identify an unknown shrub that was discovered about 25 years ago on sub-Antarctic Marion Island, one of the two Prince Edward Islands (South Africa). This evolved into a study examining the pathways that lead to the establishment of the plant, which turned out to be Ochetophila trinervis, a shrub in the family Rhamnaceae (see also this article). The species is native to southern South America, the closest population being over 7,500 km away. Dr Kalwij involved colleagues from South Africa, Australia, Argentina and Germany in this research, identifying the barn swallow as the most likely vector dispersing seeds of the plant to this sub-Antarctic island.

This week, the annual conference of the Australasian Systematic Botany Society (ASBS) is held in Brisbane. The theme of the conference is Mind the Gap and aims to highlight gaps in the field of systematics (be they biogeographic, taxonomic, data, funding, etc.). It is organised by the Queensland Herbarium and held at the Brisbane Botanic Gardens Mt Coot-tha, Toowong. About 110 delegates from Australia, New Zealand and overseas are meeting to hear 55 presentations. From the State Herbarium of South Australia, Bill Barker and Francis Nge are giving talks on the genus Lindernia and the diversification of Australia’s temperate flora, respectively.

The Proceedings of the Conference with abstracts of all presentations are available for download [1.73mb PDF] from the website. Before the Conference, a workshop was held on on how to referee taxonomic manuscripts. A field trip to Springbrook and to the precipice of the remains of the Mt Warning caldera is organised for Friday.

Information on previous meetings can be found on the ASBS website. The last Conference was held in Adelaide and the 2016 meeting took place in Alice Springs. Proceedings of both meetings were published as Swainsona Supplements and can be downloaded from our journal website.
