Common name: Atherton Oak; Oak, Atherton; Oak, Cream Silky; Creamy Silky Oak; Athertonia; Cream Silky Oak Stem Oak grain in the wood and a similar pattern in the inner blaze. Stem generally fluted. Leaves Oak grain in the twigs. Young shoots densely clothed in rusty brown hairs. Leaves variable in shape, leaf blades about 10-27 x 3.5-13 cm, teeth, if present, stiff and sharp. Midrib raised on the upper surface. Fallen leaves on the forest floor turn black upon drying. Flowers Flowers. © CSIRO Flowers paired, common peduncle about 1-2 mm long. Tepals about 19-23 mm long. Hypogynous glands four per flower. Ovules 2. Fruit Fruit about 3.6-4.1 cm long, 3.3-3.8 cm wide and 1.9-2.6 cm thick. Endocarp pitted like a peach (Prunus persica) stone. Testa bicoloured, half brown and the other half cream. The rat-eaten remains of the hard endocarp can normally be found under mature trees. Seedlings Cotyledons broadly obovate, about 13-20 x 18 mm without any obvious venation. First pair of leaves coarsely toothed. At the tenth leaf stage: leaf blade elliptic to oblanceolate, margin conspicuously Leaves and Flowers. © CSIRO toothed, hairy on both the upper and lower surfaces at least when young; terminal bud densely clothed in ferruginous hairs. Seed germination time 53 to 72 days. Distribution and Ecology Endemic to NEQ, restricted to the Mt Spurgeon-Mt Lewis area, the Gadgarra-Boonjee area on the western side of Mt Bartle Frere and the Cape Tribulation-Mt Sorrow area. Altitudinal range from near sea level to 1200 m. Usually grows in well developed upland and mountain rain forest on a variety of sites. Natural History & Notes The seeds of this species are occasionally eaten by people in North East Queensland. It is very difficult to find whole seeds on or under the trees growing in rainforest as the rats seem to get every Fruit. © CSIRO seed while still attached to the tree and only drop the empty shells to the ground. Caution should be exercised and any seeds with the flavour or odour of bitter almonds should be completely avoided. Fruit is eaten by Musky Rat-kangaroos and native rats. Cooper & Cooper (1994). Now widely cultivated, this tree produces a spreading dense crown of large lobed leaves giving excellent shade. Flowers are in long pendant racemes, emit a sweet odour in the early evening and produce large blue edible fruits. Synonyms Hicksbeachia diversifolia (C.T.White) Sleumer, Blumea 8: 6(1955).

Ecology of Proteaceae with Special Reference to the Sydney Region

Bradstock Myerscough, P.J.1, Whelan, R.J.2, and Bradstock, R.A.3 (1Institute of Wildlife Research, School of Biological Sciences (A08), University of Sydney, NSW 2006; 2Department of Biological Sciences, University of Wollongong, NSW 2522; 3Biodiversity Research and Management Division, NSW National Parks & Wildlife Service, PO Box 1967, Hurstville, NSW 1481) Ecology of Proteaceae with special reference to the Sydney region. Cunninghamia 6(4): 951–1015. In Australia, the Proteaceae are a diverse group of plants. They inhabit a wide range of environments, many of which are low in plant resources. They support a wide range of animals and other organisms, and show distinctive patterns of distribution in relation to soils, climate and geological history. These patterns of distribution, relationships with nutrients and other resources, interactions with animals and other organisms and dynamics of populations in Proteaceae are addressed in this review, particularly for the Sydney region. The Sydney region, with its wide range of environments, offers great opportunities for testing general questions in the ecology of the Proteaceae. For instance, its climate is not mediterranean, unlike the Cape region of South Africa, south- western and southern Australia, where much of the research on plants of Proteaceae growing in infertile habitats has been done. The diversity and abundance of Proteaceae vary in the Sydney region inversely with fertility of habitats. In the region’s rainforest there are few Proteaceae and their populations are sparse, whereas in heaths in the region, Proteaceae are often diverse and may dominate the canopy.

The type specimen was collected from Xishuangbanna, Yunnan Province, China. Key words—coelomycetes, identification, taxonomy Introduction The genusSphaceloma , proposed by de Bary in 1874, contains 163 named species (Index Fungorum 2013), about 52 of which are currently accepted (Kirk et al. 2008). Many species have Elsinoe teleomorphic states. In China, 24 Sphaceloma spp. have been reported (Tai 1979; Wang et al. 1999; Guo 2001, 2005). Of the five Sphaceloma spp. that have been recorded on proteaceous hosts (Elsinoe banksiae Pascoe & Crous, E. leucospermi L. Swart & Crous, E. proteae Crous & L. Swart, Sphaceloma banksiicola Pascoe & Crous, and S. protearum L. Swart & Crous), none has been reported on Helicia (Swart et al. 2001; Pascoe & Crous 2007). We describe a new species found on leaves of Helicia from China, and distinguish it from the other five species onProteaceae . The holotype specimen is conserved in Herbarium Mycologica of Yunnan Agricultural University, Kunming, China (MHYAU). Sphaceloma heliciae H.Y. Yang & Z.Y. Zhang, sp. nov.

Executive Summary Climate change is likely to have a significant effect on many trees in the City of Melbourne. Some species will perform better, while some will perform worse. The report describes the results of a project exploring the vulnerability of tree species currently planted in the City of Melbourne, and identifies some potential new species that may be more suitable for the City’s climate futures. A list of species combining those currently in the City of Melbourne’s urban forest with those being newly planted in the City of Melbourne was created. The global locations where species occur naturally and are in cultivation (and abundance where available) were compiled from existing datasets, such as ‘open data’ tree inventories and extracted from other published data, from approximately 200 cities around the world.

Triunia Kittredgei Olde (Proteaceae: Grevilleoideae: Roupaleae), a New Name for Triunia Robusta Sensu Foreman Misapplied

Peter M. Olde National Herbarium of New South Wales, Royal Botanic Gardens and Domain Trust, Mrs Macquaries Road, Sydney, NSW 2000, Australia [email protected] Abstract The name Triunia kittredgei Olde replaces Triunia robusta sensu Foreman (1986) following an invalid lectotypification. Triunia erythrocarpa Foreman is transferred to the synonymy of Triunia robusta, correctly applied. The lectotypes of T. robusta and T. montana, designated unseen by Sleumer (1955), do not appear to have been distributed to NSW. Replacement lectotypes are here designated from among the existing isolectotypes. Details of the type collection of Triunia youngiana are clarified. A new key to the genus Triunia L.A.S.Johnson & B.G.Briggs and a detailed description of the newly named Triunia kittredgei are provided, as well as a nomenclatural synopsis of the genus. Introduction Helicia youngiana (Moore and Mueller 1864, p. 84) was described from a collection made at Duck Creek on the Richmond River, New South Wales. The description concluded with the words ‘Fructus ignoti’. Charles Moore was given as the collector. Bentham (1870, p. 406) transferred Helicia youngiana to Macadamia F.Muell. F.M. Bailey (1892, p. 26) completed the diagnosis with a description of the fruit from a plant at Eumundi, south-east Queensland.
