Thelidium robustum. Line drawing by P.M. McCarthy.

Today, the State Herbarium of South Australia published one paper in the online version of the Journal of the Adelaide Botanic Gardens.

P.M. McCarthy & G. Kantvilas, Thelidium robustum sp. nov. (lichenized Ascomycota, Verrucariaceae) from Kangaroo Island, South Australia (430KB PDF).

Patrick McCarthy (formerly Australian Biological Resources Study, Canberra) and Gintaras Kantvilas (Tasmanian Herbarium, Hobart) describe a new species of lichen from Kangaroo Island. It is only known from one locality on the island, growing on limestone amongst dense coastal heathland. The authors also provide an identification key to all species of Thelidium in Australia.

The new, 5th edition of Flora of South Australia is published online in PDF-form. Today, 3 June 2016, the State Herbarium of South Australia released chapters on two closely related plant families that contain genera that are naturalised or questionably naturalised in the State: Cannabis (hemp, marijuana), Humulus (hop), Celtis (hackberry) and Ulmus (elm).

Traditionally Cannabis and Humulus were the only genera accepted in Cannabaceae. Ulmaceae consisted of two subfamilies Ulmoideae and Celtoideae (with 7 and 8 genera, respectively). Following new research, the two families were re-circumscribed in 2009 by the Angiosperm Phylogeny Group: (1) Cannabaceae now contains the former subfam. Celtoideae of Ulmaceae, incl. Cannabis and Humulus; according to molecular results, these two genera are actually part of subfam. Celtoideae and this was there fore merged with Cannabaceae. (2) The new Ulmaceae only comprises the genera in former subfam. Ulmoideae.

Ulmaceae (4.6MB PDF): Ulmus.

Cannabaceae (4MB PDF): Cannabis, Celtis & Humulus.

The Flora chapters were authored by State Herbarium botanists Chris Brodie, Peter Lang and Juergen Kellermann (Cannabaceae only).

The general link to the 5th edition of Flora of South Australia is flora.sa.gov.au/ed5, providing current treatments, glossary, introduction and cover pages for printing. Previous versions of Flora treatments are still available from our Superseded treatments page. The Flora treatments are also available on Enviro Data SA.

Today, one paper was published in the online version of the Journal of the Adelaide Botanic Gardens, Vol. 29:

A.R. Bean, The Solanum petrophilum complex (Solanaceae) revised, with the description of three new species (5MB PDF).

Solanum osteocarpum, one of the newly described species.

Tony Bean (Queensland Herbarium) revised a complex of taxa allied to the widespread Solanum petrophilum (rock nightshade, prickly nightshade). Previous authors recognised only S. eardleyae and S. petrophilum in the complex. In this paper, the author describes three new species from central Australia and splits them from S. petrophilum.

Hibbertia spanantha Toelken & A.F.Rob.

Today, the Journal of the Adelaide Botanic Gardens released three articles online:

• Greg Guerin (The University of Adelaide) publishes a new labiate species of Hemigenia from inland Western Australia: Hemigenia yalgensis (0.9MB [wpfilebase tag=fileurl id=3 linktext=’PDF’ /])
• Hellmut Toelken (State Herbarium of South Australia Hon. Research Associate) & Andy Robinson (Ku-ring-gai Council) describe a critically endangered new species of Hibbertia, only found in three small populations in northern Sydney: Hibbertia spanantha (0.7MB [wpfilebase tag=fileurl id=4 linktext=’PDF’ /]); the discovery of the new species has already attracted quite a bit of media attention last year, e.g. by The Daily Telegraph and The Age
• Gintaras Kantvilas (Tasmanian Herbarium) & Pieter van den Boom (The Netherlands) discuss the four Australian species of the lichen genus Lecania that grow on limestone and other calcareous substrates; they describe one new species from Kangaroo Island & Flinders Island (Tas.), Lecania maritima, and make a new combination (1.1MB [wpfilebase tag=fileurl id=5 linktext=’PDF’ /]).
