A team of four botanists from the State Herbarium of South Australia just returned from the Bush Blitz Expedition to Yalata Indigenous Protected Area (IPA), Wahgunyah & Fowlers Bay Conservation Parks in the Far West of the State. For two weeks, from 22 Nov. to 3 Dec. 2021, Peter Lang, Tim Hammer, Jürgen Kellermann and Tracey Spokes explored the area, surveyed the vegetation and collected new specimens for the State Herbarium collection.

We are extremely grateful to the Far West Coast people, including the Kokatha, Mirning, Wirangu, Yalata, and Maralinga Tjarutja (Oak Valley) Peoples and the descendants of Edward Roberts, the Traditional Owners of the land, for allowing us access and permitting us to collect plants.

Bush Blitz is an innovative partnership between the Australian Government, BHP Billiton Sustainable Communities and Earthwatch Australia. It is the world’s first continent-scale biodiversity survey, providing the knowledge needed to help us protect Australia’s unique animals and plants for generations to come.

New journal articles: Nov. 2021

The State Herbarium of South Australia published two articles in Vol. 35 of its journal Swainsona online, today, 18 Nov. 2021.

(1) D. Nicolle & M.E. French. A taxonomic revision of the semi-cryptic narrow-leaved mallees (Eucalyptus series Porantherae, Myrtaceae) from southern Australia. (61mb PDF).

In this large 80-page-monograph, based on extensive observations in the field and herbarium over the last 30 years, the authors revise the semi-cryptic ‘narrow-leaved mallees’, Eucalyptus ser. Porantherae, from southern Australia. They recognise a total of 23 species and 6 subspecies, many of which are described in this paper for the first time. For all taxa in the series, updated descriptions and distributions are provided (including distribution maps), as well as an identification key to the series.

(2) M. Wapstra. Hibbertia mathinnicola (Dilleniaceae), a new endemic species from northeastern Tasmania. (1.6mb PDF).

The author describes and illustrates a new endemic species of Hibbertia that is highly localised to northeastern Tasmania. Plants of this species have previously been identified as Hibbertia calycina (DC.) N.A.Wakef., but this species now considered to be restricted to mainland Australia.

New journal article: October 2021

The State Herbarium of South Australia published one lichenological paper in Vol. 35 of its journal Swainsona online, today, 29 Oct. 2021.

G. Kantvilas & A.M. Fryday, Validation of Henry Imshaug’s “Ochrolechia alectoronica” (lichenised Ascomycetes, Pertusariales), with notes on O. weymouthii Jatta and a key to the genus Ochrolechia in Tasmania. (2mb PDF).

The authors discuss two species of Ochrolechia and provide a key to all Tasmanian species. One new species is described, Ochrolechia alectoronica, using a manuscript name by Imshaug, that he used on many specimens from two islands in New Zealand’s Southern Ocean: the Auckland and Campbell islands. The species is also found in Tasmania, as is the closely related O. weymouthii, which occurs in Tasmania and Victoria.

More information about Henry Imshaug’s collections, the main set of which is held at the Michigan State University Herbarium (MSU), can be found in an article by Fryday & Prather (130kb PDF).

Bush Blitz reports available

In 2016 and 2017, State Herbarium of South Australia botanists participated in two Bush Blitz expeditions to Lake Torrens and the Great Victoria Desert. The two reports on the collections and findings about plants, fungi and algae were submitted to Bush Blitz soon after the field trips. Part of the information was presented in the official Bush Blitz survey reports, but not the full data.

The detailed reports on both expeditions are now available:

(1) Lang, P.J., Kellermann, J., Bell, G.H., Brodie, C.J., Vonow, H.P. & Waycott, M. (2018). Lake Torrens Bush Blitz survey: Vascular plants, cyanobacteria, algae, bryophytes, lichens and macrofungi. Report for Bush Blitz, Australian Biological Resources Study, Canberra. (State Herbarium of South Australia: Adelaide). (5.1mb PDF).

The 2016 Bush Blitz Survey to Lake Torrens and five adjoining pastoral leases provided an opportunity to greatly increase the knowledge on the flora of the area. The preceding seasonal rainfall provided high quality conditions for plant growth and flowering and also the presence of water in areas of Lake Torrens and surrounds. A total of 382 unique taxa were recorded on the survey, comprising 358 vascular plants, 1 bryophyte, 4 algae, and 7 cyanobacteria; 12 lichens were also recorded.

Significantly, 32 vascular plant taxa and 6 cryptogams (1 bryophyte, 3 cyanobacteria, 2 algae) were recorded from the study area for the first time.

Including previous records, this resulted in a total of 699 vascular plants for the survey area, of which 30 are introduced, weedy plants. Five of the weed taxa are highlighted as needing control measures while they are still in low numbers. The remaining 25 weed taxa are of low concern, but should be monitored. In total, 60 cryptogams are recorded for the area, including 18 bryophytes, 4 algae, 7 cyanobacteria, 12 lichens and 19 fungi. Non-lichenous fungi are covered in a separate report by T. Lebel, but the 16 taxa recorded on survey are also listed in Appendix III.

The survey resulted in the collection of 996 specimens and complementary observational records. Leaf samples in silica gel for future DNA analysis were collected from almost all specimens.

The 2017 Bush Blitz Survey to the Great Victoria Desert (GVD) targeted Mamungari Conservation Park (CP) and the adjoining area of the Maralinga Tjarutja Lands. It provided an opportunity to greatly increase the knowledge on the flora of the area.

The survey resulted in the collection of 660 specimens with nearly all the vascular plant collections having duplicate samples for PERTH herbarium plus leaf tissue samples in silica gel for future DNA analysis. The collections comprise 539 vascular plants, 25 bryophytes, 18 macrofungi and 78 lichens. These represent 358 unique taxa (excluding hybrids and intergrades), comprising 319 vascular plants, 9 bryophytes, 12 macrofungi and 18 lichens.

A validated checklist for the area was compiled, incorporating ALA specimen based records. The total number of accepted vascular plant taxa is 529 for the GVD study area and 436 for Mamungari CP. The Bush Blitz Survey resulted in a total of 48 vascular plant taxa beingcollected from the study area for the first time, with two of these also new records for South Australia (SA).

The checklist for cryptogams comprises 73 taxa (20 bryophytes, 19 fungi and 34 lichens), but due to limitations of available historical data this is not a definitive list for those groups. Four of the cryptogam taxa collected on survey are potentially new to SA.
