State Herbarium celebrations

This week, on 9 Dec. 2014, over 90 current and former staff members, volunteers, plant collectors, State Herbarium friends and other guests gathered in the National Wine Centre of Australia to celebrate the 60th anniversary of the State Herbarium of South Australia. This also launched a year of celebrations, with other functions, seminars and talks being planned for 2015.

The State Herbarium was established in 1954 by bringing together several different herbaria from The University of Adelaide, the South Australian Museum and other private and institutional collections.  With about 1.035 million specimens, it is now one of the largest herbaria in Australia.

The Celebrations started with an acknowledgment of the Aboriginal inhabitants of the Adelaide area by State Herbarium Manager Peter Canty. This was followed by Helena Jenkinson from the Board of the Botanic Gardens and State Herbarium, who welcomed everyone to the function. Chief Botanist Prof. Michelle Waycott, then spoke about the history of the State Herbarium and its function today.

New Journal volume, Dec. 2014

Today, 1 Dec. 2014, a new special volume of the Journal of the Adelaide Botanic Gardens was published.  Volume 28 of the Journal consists of one article: P.S. Short’s magnum opus, the revision of the Australian species of Brachyscome (Asteraceae).

A taxonomic review of Brachyscome s.lat. (Asteraceae: Astereae), including descriptions of a new genus, Roebuckia, new species and new infraspecific taxa. (10mb PDF)

The 219 page article is the result of over 20 years’ of research. All Australian species of Brachyscome and related genera are reviewed. 17 new species and 4 subspecies of Brachyscome are described as new, totalling the number of species of the genus to 87. The new genus Roebuckia is split from Brachyscome. It is named after William Dampier’s ship, the Roebuck, which landed on the W.A. coast in 1699. Roebuckia contains 9 species, of which 5 species are new described, as well as 5 new varieties.

The paper is illustrated with photographs and very detailed line-drawings of fruits by botanical artist Sue Wickison from New Zealand. The articles concludes with a large appendix, listing the character states for 87 morphological and other characters for all species discussed.

Soil seed banks and the restoration of plant biodiversity in an arid zone habitat

It’s All About the Plants

Witchelina M.Whalen talk 600x450Predicting the response of native vegetation in Australia’s arid rangelands to management actions, such as changing grazing regimes, is often hampered by a lack of knowledge regarding the nature of native plant biodiversity at a local scale. Simply measuring above-ground plant species richness can be quite misleading because in arid habitats, much of a site’s plant diversity, particularly that of short-lived species, may be present as dormant seeds in the soil seed bank. We are investigating factors influencing variation in both above- and below-ground plant diversity in a large (ca. 420,000 km2) conservation reserve in arid South Australia. This reserve, Witchelina, has a long history (ca. 140 years) of pastoral use, but was destocked in 2010 when it was purchased by the Nature Foundation of South Australia. Particular factors being investigated include variation among different habitats and effects of past grazing intensities. For example, we are comparing the diversity and composition of the seed banks and above-ground vegetation in areas close to watering points with a history of heavy grazing with those of areas more distant from watering points that have been less heavily grazed. Alison Nicolson will also speak about her honours research on Witchelina, for which she used existing DEWNR photopoints monitoring sites at Witchelina to study regeneration since 1999. By comparing, photopoint photos taken in 2014 with field measurements, she has also been able to evaluate the reliability of using photopoints alone as a monitoring tool.

All Herbarium staff, honoraries, volunteers, students and guests welcome.

New Flora chapter published, Nov. 2014

Eucalyptus alatissima

Today, 17 Nov. 2014, the first part of the chapter of Myrtaceae (32.9mb) for the 5th edition of Flora of South Australia was published. On 102 pages, the author Dean Nicolle describes all native and naturalised taxa of Eucalyptus, Corymbia and Angophora, occurring in South Australia. Identification keys are provided and most species are illustrated with drawings and photographs. Other genera of Myrtaceae are in preparation and will be published shortly.

With over 100 species this is one of the largest and most complex chapters published to date, editing of which took over two years and included extensive work on plant distributions and synonyms, to bring the Flora chapter and the SA Plant Census in synch. Many thanks to Robyn Barker and Peter Lang for their help during this time.

The general link to the 5th edition of Flora of South Australia is flora.sa.gov.au, providing current treatments, glossary, introduction and cover pages for printing. Previous versions of Flora treatments are still available from our Superseded treatments page.
