Two publications from the State Herbarium of South Australia were released this month:

(1) Today, one paper was published in the online version of the Journal of the Adelaide Botanic Gardens.

P.S. Catcheside, H.P. Vonow & D.E.A. Catcheside, Entoloma ravinense (Agaricales, Basidiomycota), a new species from South Australia (1.8MB PDF).

State Herbarium Hon. Associate Pam Catcheside and colleagues describe a new fungus they discovered in the Ravine des Casoars Wilderness Protection Area, Kangaroo Island. The type collection is particularly significant for South Australia, as it was accessioned as the millionth specimen at the State Herbarium in 2012. The authors examined the new species with morphological and molecular methods, discuss their results in detail, provide photographs and a key to Australian species of pleurotoid (lateral attached) entolomas.

See also the report on the millionth specimen in the Board of the Botanic Gardens and State Herbarium Annual Report 2012-2012 (p. 14).

(2) In addition, the State Herbarium also published a new brochure on hybridisation between native and introduced species of Carpobrotus (pigface).

M. Waycott, Hybridisation in native pigface, Carpobrotus rossii (8pp., 5MB PDF).

Carpobrotus rossii, male plant.

This brochure summarises the results of a research project by the State Herbarium of South Australia, funded by the Adelaide and Mt Lofty Ranges NRM Board (AMLR), on the invasive species Carpobrotus edulis (L.) N.E.Br. and its hybrids with the native Carpobrotus rossii (Haw.) Schwantes. Illustrations and keys to species of Carpobrotus in the Adelaide coastal regions are provided.

Several staff and Hon. Associates of the State Herbarium, as well as one summer scholarship student and collaborators at The University of Adelaide, were involved in the project. The results indicate that hybridisation between the two species is common in areas where both species occur and identification of hybrids is complex.

Hardcopy of the booklet is available from the AMLR main office at 205 Greenhill Road, Eastwood SA 5063, and will soon be distributed to other offices in the region.

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.
