Grasses keys online

Several years ago, the State Herbarium of South Australia published Grasses of South Australia by J.P. Jessop, G.R.M. Dashorst & F.M. James in collaboration with Wakefield Press. This is the well-known standard work on the grass family Poaceae for the State and can also be used in adjacent regions of other States.

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.

New eucalypt phylogeny

Last month, Dr Andrew Thornhill started working at the State Herbarium of South Australia.  Originally from Melbourne, Andrew studied and worked at Monash University (Melbourne), the Australian National University, Australian National Herbarium and CSIRO (all Canberra), the Australian Tropical Herbarium (Cairns), the University of California (Berkeley, USA) and the federal Department of Agriculture and Water Resources (Canberra). In his current position, he is working for both, The University of Adelaide and the State Herbarium on a variety of projects, including the analysis of molecular data-sets and re-organisation of the Herbarium’s bryophyte collection.

In 2011, Andrew started a project on creating a complete species level phylogeny of the eucalypts (which include the genera Eucalyptus, Angophora and Corymbia). The idea was to sample DNA for as many eucalypt species as possible, combine that data and see how all of the species were related to each other. This week, over seven years later, the project was published.

Thornhill, A.H., Crisp, M.D., Külheim, C., Lam, K.E., Nelson, L.A., Yeate,s D.K., Miller, J.T. (2019). A dated molecular perspective of eucalypt taxonomy, evolution and diversification. Australian Systematic Botany 32: 29-48.

There are over 800 described eucalypt species in the world and we are close to soon having 900. Around 1/8th of the total number of eucalypt species are native to South Australia and they grow in the arid and forest areas in an array of habits, be it mallees or trees up in the hills.

The paper presents a dated phylogeny of the Australian eucalypts and a diversification analysis to show if any parts of the eucalypt phylogeny have had accelerated diversification. What Andrew and his colleagues found was that many of the species that grow in the arid and forest areas of southern and south-eastern Australia have only evolved in the last two million years, this includes many of the eucalypt species that grow in South Australia. Their origin comes due to a divergence with Western Australian eucalypts, but that’s not to say that Western Australia is where eucalypts originated. There are even deeper splits in the history of eucalypts that suggests that either south-west Western Australia or south-east Queensland could be the source of origin. One way to find this out may be by finding new ‘oldest’ fossils in either of these places, which would help provide evidence that eucalypts grew there in the deep past.

The results of this research are also discussed by Andrew in an article in The Conversation. The treatment for eucalypts in the new, 5th edition of the Flora of South Australia is also available (33.7mb PDF).

New journal articles: Mar. 2019

Today, the State Herbarium of South Australia published two article in the online version of Swainsona.

(1) J.G. Conran, Weird and wonderful plants of South Australia (2.3mb PDF)

This article is published in Vol. 30 of the journal, which contains the Proceedings of the Botany SymposiumBotany 2016 — Past, present and future“, held at the 2016 NRM Science Conference, to celebrate the 60th anniversary of the State Herbarium.

John Conran‘s contribution to the Conference was an overview of interesting plants in the State. He discusses tiny Trithuria plants, carnivorous sundews, triggerplants with spring-loaded pollination mechanisms, parasitic plants like mistletoes, quandongs and snotty gobbles, and many others.

Eyre Peninsula plants book

A new book on the plants of southern Eyre Peninsula has just been published:

Saunders, Brian (2018). Flowering plants of lower Eyre Peninsula: An illustrated tour of the native flora, 200 pp. Camden Park: Lane Print & Post.

The book is a photographic identification guide to the more common plants of the area, with brief notes on their distribution and biology. The southern half of Eyre Peninsula is home to many remarkable plants, including some which are endemic to the region. A list of all EP native plants can be found through the eFloraSA website.

State Herbarium of South Australia botanist Peter Lang was heavily involved in the book project, advising Brian on the correct names of plants and checking text and images.

The publication is available in shops in Coffin Bay, Port Lincoln and Adelaide at $25.

Other well-known identification guides by the author include:

 

New journal article: Nov. 2018

The State Herbarium of South Australia published one article in the online version of Vol. 30 of the journal Swainsona, today. This volume of the journal contains the Proceedings of the Botany SymposiumBotany 2016 — Past, present and future“, which was held at the 2016 NRM Science Conference. to celebrate the 60th anniversary of the State Herbarium.

The authors review the history and current status of phycological research in South Australia. They point to the importance of Prof. Bryan Womersley‘s work, whose Marine benthic flora of southern Australia (1984-2003) documented the algal diversity of our coasts in exemplary detail and critically revised many groups of algae. They also discuss the impact of new molecular methods and the continuing importance of herbaria, as well as pointing out some current and future challenges.
