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 Previous versions of Flora treatments are still available from our Superseded treatments page.

Mundulla Primary School Herbarium Project

It’s All About the Plants
Monday, 15 December 2014, 2:00–3:00
Ground Floor Meeting & Lunch Room, Tram Barn

Note changed date and time!

by Dee Provis

Dee Provis, a local naturalist and community volunteer from Mundulla, in the upper South East, has kindly offered to come and tell us about the Mundulla Primary School Herbarium Project she set up. The project involved the State Herbarium’s Weeds Botanist Chris Brodie, who also attended the launch of the project. This is a great example of how different levels of government and the community can partner to achieve positive outcomes for education and the local environment.

The aims of the Herbarium Project are

…To involve students in basic plant science, using both indigenous and exotic plants from our rare Grey Box Grassy Woodland.

To teach students how to:

  • Identify both native plants and exotic species (weeds/garden escapees)
  • Collect, mount, arrange and catalogue plant samples according to the strict protocols required by the State Herbarium
  • Make this information available to the wider community by publications, DVD & website

To increase the body of knowledge held within the local community of both indigenous and exotic plants. This resource will support locals in identifying weeds for removal and facilitate native plant retention and regeneration.

The Herbarium Project has been funded by a Natural Resources Management Action Grant in 2014.

Art about Jessie L. Hussey

Here is a first look at some more artwork created by Lisa Waters. It is inspired by her research on the life and work of 19th century amateur botanist and collector Jessie L. Hussey.

Lisa says

…Jessie L. Hussey had a significant collaboration with Prof. Jacob Agardh of Lund, Sweden, who was the leading phycologist of his time. Sadly Jessie died in March 1899, only aged 36, with so many plans left unfinished, whilst Prof. J Agardh was able to live a long and productive life working on his beloved algae up until his death at age 87 in January 1901.

After Jessie’s death Agardh continued to work on her algae specimens and one of the last things he did was describe a new genus from her collections, which he named in her honour in a paper published after his death in 1901. The genus Husseya has one species, which he named Husseya australis. Diagnostic characters for this species include a distinctive central cell structure and that older plants grow a thick outer wall of cells which is absent in younger plants.

These two paintings are of transverse sections of Husseya australis as seen under a high powered microscope and represent the collaboration between Jessie and Agardh. The younger plant represents Jessie, who did not get to live the long productive life she had planned and therefore did not get to develop the thick outer wall of cells. The older plant represents Agardh, who lived a long productive life and was able to develop the intricate outer wall of cells.

The current name for Husseya australis is Husseya rubra. The Algae revealed fact-sheet for this species can be found here on the eFloraSA web-site.

New Journal articles, Oct. 2014

Yesterday, 29 Oct. 2014, the Journal of the Adelaide Botanic Gardens published two new articles online:

  • H.R. Toelken: Notes on Hibbertia (Dilleniaceae) 10. Hibbertia hirsuta (subgen. Hemistemma: H. vestita group) does occur in South Australia and Tasmania. (600kb PDF)
  • G. Kantvilas & J.A. Elix: Additions to the genus Lecidella (lichenised Ascomycota: Lecanoraceae). (820kb PDF)

Lecidella leucomarginata, a new lichen described by Kantvilas & Elix. Scale bar = 1 mm.

State Herbarium of South Australia Hon. Research Associate Hellmut Toelken discusses the rediscovery of Hibbertia hirsuta in south-eastern South Australia, 130 years after it was first collected in the State. For a long time the species was thought to only occur in Tasmania.

Lichenologists Gintaras Kantvilas (Tasmanian Herbarium, Hobart) and Jack Elix (Australian National University, Canberra) describe one new species and one new subspecies of the lichen genus Lecidella; their paper also includes a key to the genus for temperate Australia.
