  • One New Endemic Plant Species on Average Per Month in New Caledonia, Including Eight More New Species from Île Art (Belep Islan
    CSIRO PUBLISHING Australian Systematic Botany, 2018, 31, 448–480 https://doi.org/10.1071/SB18016 One new endemic plant species on average per month in New Caledonia, including eight more new species from Île Art (Belep Islands), a major micro-hotspot in need of protection Gildas Gâteblé A,G, Laure Barrabé B, Gordon McPherson C, Jérôme Munzinger D, Neil Snow E and Ulf Swenson F AInstitut Agronomique Néo-Calédonien, Equipe ARBOREAL, BP 711, 98810 Mont-Dore, New Caledonia.

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.

  • Austromyrtus Dulcis
    Plant of the Month - March by Allan Carr Austromyrtus dulcis midyim Pronunciation: os-tro-MERT-us DULL-sis MYRTACEAE Derivation: Austromyrtus, from the Latin, australis – south (related to the genus Myrtus but in the south - Australia): dulcis, from the Latin, dulcis – sweet tasting. Leaves, flowers, fruit Flush of new leaves Austromyrtus now is a genus of just 3 species. Most of the species once placed in this genus are now assigned to Gossia and some to Lenwebbia. Description: A. dulcis is a common sprawling shrub to about 1 m in coastal sandy areas of heathland, scrub and open forest from Fraser Island in Qld to Byron Bay in NSW. It has flushes of new growth of pink or red leaves later changing to a coppery-bronze hue before becoming green. As with all Myrtaceae here they are now potentially threatened by Myrtle Rust. Plants growing near where I have removed a rust affected Chamelaucium so far seem to be resistant. Leaves to 30 mm x 15 mm are opposite, *discolorous and hairy below. They are glossy green above, white to greyish below and aromatic when crushed due to dense translucent oil dots below. These are visible with a hand lens. Flowers are 5-petalled, open and white to 8 mm across with many *stamens and borne from September to March, They are usually solitary or in short *racemes in the leaf axils. Fruits are white berries to 10 mm diameter covered in small dark purple spots, giving them a pale mauve appearance. They are sweet and gritty due to 3 to 9 tiny, pale brown seeds and delicious with ice-cream and apparently make good jam.

  • 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.
