The New Caledonian biodiversity hotspot contains many micro-hotspots that exhibit high plant micro- endemism, and that are facing different types and intensities of threats. The Belep archipelago, and especially Île Art, with 24 and 21 respective narrowly endemic species (1 Extinct,21Critically Endangered and 2 Endangered), should be considered as the most sensitive micro-hotspot of plant diversity in New Caledonia because of the high anthropogenic threat of fire. Nano-hotspots could also be defined for the low forest remnants of the southern and northern plateaus of Île Art. With an average rate of more than one new species described for New Caledonia each month since January 2000 and five new endemics for the Belep archipelago since 2009, the state of knowledge of the flora is steadily improving.

Conservation Advice Gossia Gonoclada Angle-Stemmed Myrtle
THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister’s delegate approved this Conservation Advice on 16/12/2016. Conservation Advice Gossia gonoclada angle-stemmed myrtle Conservation Status Gossia gonoclada (the angle-stemmed myrtle) is listed Endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) effective from the 16 July 2000 . The species was eligible for listing under the EPBC Act as on 16 July 2000 it was listed as Endangered under Schedule 1 of the preceding Act, the Endangered Species Protection Act 1992 (Cwlth). Species can also be listed as threatened under state and territory legislation. For information on the current listing status of this species under relevant state or territory legislation, see http://www.environment.gov.au/cgi-bin/sprat/public/sprat.pl . The main factors that are the cause of the species being eligible for listing in the Endangered category are its small population size and restricted distribution . Description The angle-stemmed myrtle is a tree growing to 18 m tall. The bark of the trunk is smooth to flaky, pale brown, reddish, orangish, or gray. Branchlets are distinctly four-angled to laterally compressed and leaves are slightly discolorous, matte or slightly glossy above and matte below. The winged branchlets, slightly retuse leaf apex and five merous flowers distinguish G. gonoclada from other species of the genus in south-east Queensland (Snow et al., 2003). Distribution The angle-stemmed myrtle is endemic to south-east Queensland along the lower reaches of the Brisbane and Logan rivers.

New Species of Eugenia and Gossia (Myrtaceae: Myrteae) from Papua New Guinea
Telopea 12(4) 453–461 New species of Eugenia and Gossia (Myrtaceae: Myrteae) from Papua New Guinea Neil Snow1 and Peter G. Wilson2 1 Herbarium Pacificum, Bishop Museum, 1525 Bernice Street, Honolulu, HI 96817, U.S.A. Email: [email protected] 2National Herbarium of New South Wales, Royal Botanic Gardens, Sydney, NSW 2000 Australia. Email: [email protected] Abstract Two new species of Myrtaceae are proposed for Papua New Guinea: Eugenia craveniana N. Snow & Peter G. Wilson and Gossia yelana N. Snow & Peter G. Wilson.Each species is known from a single gathering. Eugenia craveniana is contrasted with E. reinwardtiana and E. salomonica, congeneric species also occurring in Papuasia. Gossia yelana represents the seventh confirmed species of the genus for New Guinea, but none of the species appear to be common there. Although fruiting material is needed to unambiguously place both species into their respective genera, a suite of other characters and the process of elimination allow us to propose them as new species. A conservation designation of Vulnerable is proposed for both species. This paper represents Contribution No. 2009–012 to the Pacific Biological Survey. Introduction Ongoing curatorial work at Bishop Museum and the Royal Botanic Gardens, Sydney, has revealed two taxa that do not fit into currently recognised species limits among the flora of Papua New Guinea. The purpose of this paper is to propose one new species each for Eugenia and Gossia, discuss their distributions, and comment on morphologically similar species. Methods Collections of material were examined primarily from BISH, NSW, and in some cases from other institutions.

Lose the Plot: Cost-Effective Survey of the Peak Range, Central Queensland
Lose the plot: cost-effective survey of the Peak Range, central Queensland. Don W. Butlera and Rod J. Fensham Queensland Herbarium, Environmental Protection Agency, Mt Coot-tha Botanic Gardens, Mt Coot-tha Road, Toowong, QLD, 4066 AUSTRALIA. aCorresponding author, email: [email protected] Abstract: The Peak Range (22˚ 28’ S; 147˚ 53’ E) is an archipelago of rocky peaks set in grassy basalt rolling-plains, east of Clermont in central Queensland. This report describes the flora and vegetation based on surveys of 26 peaks. The survey recorded all plant species encountered on traverses of distinct habitat zones, which included the ‘matrix’ adjacent to each peak. The method involved effort comparable to a general flora survey but provided sufficient information to also describe floristic association among peaks, broad habitat types, and contrast vegetation on the peaks with the surrounding landscape matrix. The flora of the Peak Range includes at least 507 native vascular plant species, representing 84 plant families. Exotic species are relatively few, with 36 species recorded, but can be quite prominent in some situations. The most abundant exotic plants are the grass Melinis repens and the forb Bidens bipinnata. Plant distribution patterns among peaks suggest three primary groups related to position within the range and geology. The Peak Range makes a substantial contribution to the botanical diversity of its region and harbours several endemic plants among a flora clearly distinct from that of the surrounding terrain. The distinctiveness of the range’s flora is due to two habitat components: dry rainforest patches reliant upon fire protection afforded by cliffs and scree, and; rocky summits and hillsides supporting xeric shrublands.

Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific
Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific Craig Costion School of Earth and Environmental Sciences Department of Ecology and Evolutionary Biology University of Adelaide Adelaide, SA 5005 Thesis by publication submitted for the degree of Doctor of Philosophy in Ecology and Evolutionary Biology July 2011 ABSTRACT This thesis advances plant biodiversity knowledge in three separate bioregions, Micronesia, the Queensland Wet Tropics, and South Australia. A systematic treatment of the endemic flora of Micronesia is presented for the first time thus advancing alpha taxonomy for the Micronesia-Polynesia biodiversity hotspot region. The recognized species boundaries are used in combination with all known botanical collections as a basis for assessing the degree of threat for the endemic plants of the Palau archipelago located at the western most edge of Micronesia’s Caroline Islands. A preliminary assessment is conducted utilizing the IUCN red list Criteria followed by a new proposed alternative methodology that enables a degree of threat to be established utilizing existing data. Historical records and archaeological evidence are reviewed to establish the minimum extent of deforestation on the islands of Palau since the arrival of humans. This enabled a quantification of population declines of the majority of plants endemic to the archipelago. In the state of South Australia, the importance of establishing concepts of endemism is emphasized even further. A thorough scientific assessment is presented on the state’s proposed biological corridor reserve network. The report highlights the exclusion from the reserve system of one of the state’s most important hotspots of plant endemism that is highly threatened from habitat fragmentation and promotes the use of biodiversity indices to guide conservation priorities in setting up reserve networks.

ISSN O811 5362. ______________________________________________________________________ NEWSLETTER NUMBER 55. DECEMBER 2008. ______________________________________________________________________ 323 Philp Ave Frenchville Qld. 4701 19/12/2008 Dear Members and subscribers, Well, Spring well and truly sprung, and after the coldest winter for years, we almost missed it and went straight into Summer. And Summer we are having!! Very, very hot; very, very humid; quite like old times actually. The air is heavy, everything is green, and the grass grows as you watch. A word of warning: DON'T plant Cheeky Yam ( Dioscorea bulbifera ) in your home garden unless you have both an enormous amount of room, and plan to eat an enormous amount of the vegetable. In the current conditions it has resurrected itself and taken off with a vengeance, choking and smothering everything nearby, and eradicating it is proving very difficult indeed. The cold winter resulted in a bumper crop of raspberries ( Rubus probus ) which was very welcome after the poor harvests of the previous couple of years, and both types of native violets (Viola hederacea, H.betonifolia ) thrived. The flowers have made an interesting addition to salads. I have actually been given a jar of French Violet Petal jam, which is delicately flavoured and perfumed, but I haven't got round to trying my hand at jam making with the native ones yet. We found the best Sandpaper Fig ( Ficus opposita ) fruit we've tasted for years at our SGAP breakup on 7 th December, at the park out at Cammoo Caves. The barred caves and walks are now part of The Caves National Park.

Rapid Field Assessments of Impacts of Plant Fungal Pathogen Austropuccinia Psidii on Five High Priority Myrtaceae Species in New South Wales, Australia
Cunninghamia Date of Publication: March 2019 A journal of plant ecology for eastern Australia ISSN 0727- 9620 (print) • ISSN 2200 - 405X (Online) Rapid field assessments of impacts of plant fungal pathogen Austropuccinia psidii on five high priority Myrtaceae species in New South Wales, Australia Anthony Manea1*, Laura Fernandez Winzer1 and Michelle R. Leishman1 1Department of Biological Sciences, Macquarie University, North Ryde, NSW 2109, AUSTRALIA *Corresponding author: [email protected] Abstract: In 2010, the plant fungal pathogen Austropuccinia psidii was detected in Australia. It has since spread rapidly through the eastern states of Australia causing significant population declines in a number of susceptible species. However, there are still a number of potentially vulnerable species that lack the necessary field observations that are needed to accurately gauge the risk Austropuccinia psidii poses to them. Because of this, rapid field assessments of these species have been given the utmost priority. In the spring of 2018 (October) we carried out rapid field assessments for five high priority species. We did not observe active Austropuccinia psidii infection on any of the species at the time of assessment despite the majority of individuals having susceptible new flush. However, we did find evidence of significant previous infection (branch dieback) in the largest Archirhodomyrtus beckleri population we assessed. Therefore, to confirm our observations, it is necessary to re-assess this population when environmental conditions
