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

In Vol. 30 we continue to publish papers from the Proceedings of the Botany Symposium “Botany 2016 — Past, present and future“, which was held at the 2016 NRM Science Conference. to celebrate the 60th anniversary of the State Herbarium.

(1) G.R. Guerin, M.J. Christmas, B. Sparrow & A.J. Lowe, Projected climate change implications for the South Australian flora (0.6mb PDF).

The authors explore the implications of climatic warming for individual plant species and the State’s plant biodiversity. As case study they use Dodonaea viscosa subsp. angustissima. The authors conclude that significant climate change will influence ecophysiology, leading to changes in primary productivity and water stress. This is predicted to ultimately lead to lower species richness, altered species composition and more uneven abundances.

Vol. 31 of Swainsona contains one new taxonomic paper.

(2) W.R. Barker, Notes on the taxonomy of Australian Lindernia subg. Didymadenia (Linderniaceae) (1.3mb PDF).

Subgenus Didymadenia (Linderniaceae) contains the majority of taxa of Lindernia that occur in Australia. Bill Barker divides the subgenus into five sections and describes 22 new species. The typification of 5 existing taxa is discussed and resolved. This paper is partly based on the most recent phylogeny of Lindernia by Ed Biffin and co-authors, which will be published shortly in Australian Systematic Botany. It is a precursor to a forthcoming larger study of the genus.
