Life in the pond: Leibleinia

Bob Baldock reports on algae found in the Botanic Gardens recycle-ponds: this time on a spiral blue-green alga that entwines a green alga!

Leibleiena epiphytica on Oedogonium sp.

Leibleinia epiphytica (arrowed in photograph) is a cosmopolitan, extremely thin, thread-like photosynthetic bacterium (Cyanophyte, or blue-green alga) that wraps itself around threads of other algae. Here it has embraced the common green alga, Oedogonium.  Both were found in the small rafts of algae floating in recycle ponds.

Amazing what you find under the microscope!

Open House Adelaide 2014

OpenHouse_3The State Herbarium will be open to the public on 3 and 4 May 2014 during Open House Adelaide as part of the About Time: South Australia’s History Festival.

The heritage-listed 1909 Tram Barn A was once part of a complex housing the Adelaide tram fleet.  Now the State Herbarium, it houses over one million plant specimens instead. See some of the first plants collected in the State on Matthew Flinders‘ voyage and learn how all these dried specimens are critical to the effective preservation of living plants.

Read more about Tram Barn A (1.15mb pdf) and the over one million plant specimens (561kb pdf) in booklets published by State Herbarium staff.

Guided walking tours will be available on both 3 and 4 May at 11am and 1pm.

Bookings are essential.

Jessie Hussey inspires school teachers

State Herbarium of South Australia, specimen AD 96920168

Pimelea husseyana was named after Jessie Hussey by Ferdinand von Mueller in 1894; it is now called Pimelea phylicoides. This specimen collected in 1897.

This week, Lisa Waters from the State Herbarium gave a presentation to a group of 50 primary school teachers about her research on the 19th century plant collector and amateur botanist Jessie Hussey. She was invited by Prof. Martin Westwell (Flinder Centre for Science Education in the 21st Century, Flinders University), who is currently Scientist in Residence at the Department for Education and Child Development (DECD), working with teachers on the science curriculum, with particular emphasis on the Science as a human endeavour strand.

Jessie Hussey lived from 1862–1899 in Port Elliot. Her passion for botany helped her to make a significant and pioneering contribution to the knowledge of South Australia’s terrestrial and marine flora during the 1890s. She became a respected collaborator of many leading national and international botanists and phycologists.

Lisa is researching the life and work of Jessie Hussey for over 5 years. In 2012 she travelled to Europe on a Churchill Fellowship, to visit herbaria in Sweden, Germany, Great Britain and Ireland, where specimens collected by Jessie Hussey are held, as well as many of the letters she wrote to overseas scientists.

Jessie’s story, and Lisa’s own story of investigating Jessie’s life and work, provided us with inspiring examples of how science can really come alive and be much more meaningful when we hear the personal stories involved. — Prof. Martin Westwell
