FLORA AND FAUNA GUARANTEE - SCIENTIFIC ADVISORY COMMITTEE
PRELIMINARY RECOMMENDATION ON A NOMINATION FOR LISTING
Olearia passerinoides subsp. glutescens (Sond.) D.A.Cooke - Shiny Daisy-bush
Flora and Fauna Guarantee logo
Date of consideration:
Validity:
29 April, 14 July 2015
The nomination is for a valid item.
Prescribed Information:
The prescribed information was provided.
File No.: FF/54/3687
Name of the Nominator is adequately provided.
Name of the Item is adequately provided.
The nominated taxon is accepted by the Scientific Advisory Committee (SAC) as a valid taxon because it has been formally
described and it is accepted as a valid taxon by the National Herbarium of Victoria.
Shiny Daisy-bush Olearia passerinoides subsp. glutescens is a glutinous shrub of the Asteraceae family growing to 2.5m
tall. Leaves are 6-25 mm long, and spreading. Heads occur in small corymbose clusters, with peduncles approx. 14 mm
long. Ray florets are 6-8 and disc florets 8-9 (The Royal Botanic Gardens and Domain Trust 2015). Flowers have white or
pale mauve petals, and appear irregularly throughout the year. When not in flower, Shiny Daisy-bush closely resembles
Chinese Scrub (Cassinia sp.), an indigenous plant which is widespread across the goldfields region of Victoria. The species
has been recorded from mallee and dry woodland communities, usually on infertile soils (Walsh 2014). In the Inglewood
district of Victoria it is found in box-ironbark Forest. It occurs in dense clusters under an open to moderately dense
canopy of Grey Box (Eucalyptus microcarpa) and Yellow Gum (E. leucoxylon), and less frequently under Bull Mallee (E.
behriana) or Blue Mallee (E. polybractea).
Eligibility for listing as a taxon under the Flora and Fauna Guarantee
The nominated item satisfies at least one criterion of the set of criteria prepared and maintained under Section 11 of the
Flora and Fauna Guarantee Act 1988, and stated in Schedule 1 of the Flora and Fauna Guarantee Regulations 2011.
Evidence that criteria are satisfied:
Sub-criterion 1.2.1 the taxon is very rare in terms of abundance or distribution.
Evidence:
The known geographic distribution of Shiny Daisy-bush in Victoria spans just two linear kilometres, and occupies a
collective area totalling not more than 280 square metres. The Victorian population is unlikely to exceed 150 plants,
and may be as low as five.
Sub-criterion 1.2.3 the reproduction or recruitment of the taxon has seriously declined or is not occurring
Evidence:
Field observations indicate that Shiny Daisy-bush produces little or no viable seed, and there is no evidence that
recruitment from seed is occurring in the Inglewood population.
Additional information
-
-
Shiny Daisy-bush is distributed from SA to Victoria. In SA the subspecies is restricted to areas of higher rainfall (Cooke
1985). There are two collections from the border of SA and VIC and the disjunct population near Inglewood, Victoria
(Australia’s Virtual Herbarium 2015). The taxon is thus an edge of range species.
Olearia passerinoides subsp. glutescens is currently classified as ‘Endangered’ in Victoria (DEPI 2014).
The National Herbarium of Victoria (MEL) at the Royal Botanic Gardens Victoria hold two records of this subspecies from
Victoria; one identified as the ‘Entrance of the Glenelg R[iver]’, collected in 1891 and a second record from 2010
representing the population in the current nomination
Documentation
The published information cited has been assessed. Based on the evidence available to it, the SAC believes that the data
presented are not the subject of scientific dispute and the inferences drawn are reasonable and well supported.
NOMINATION NO. 863
Preliminary Recommendation of the Scientific Advisory Committee
The Scientific Advisory Committee concludes that on the evidence available the nominated item is eligible for listing in
accordance with Section 11(1) of the Act because sub-criteria 1.2.1 and 1.2.3 of the Flora and Fauna Guarantee Regulations
2011 have been satisfied. The SAC therefore makes a preliminary recommendation that the nominated item be supported
for listing under the Flora and Fauna Guarantee Act 1988.
