Conospermum taxifolium Family: Proteaceae Distribution: Woodlands and heath of eastern Australia from south-east Queensland to eastern Tasmania Common Variable smokebush Names: Derivation of Conospermum....from Greek konos, a cone and sperma, Name: a seed, a reference to the appearance of the seeds. taxifolium....having foliage similar to the genus Taxus, the Yew. Conservation Not considered to be at risk in the wild. Status: General Description: Conospermum is a genus of about 50 species, all of which occur only in Australia. Most are found in the south of Western Australia but a few can be found in the eastern states. They are generally called "smokebushes" because, with some species, the appearance of the flowering plant from a distance resembles puffs of smoke. Conospermum taxifolium Photo: Jill Dark Conospermum taxifolium is a small, erect shrub rarely more than about 50 cm high. It is quite variable in habit and several forms exist. The leaves may be linear to elliptical in shape from 5-30 mm long by about 1-5 mm wide and are usually slightly twisted. The white flowers are individually quite small (about 75 mm long) but occur in clusters at the ends of the branches. Flowering occurs in late spring. C.ellipticum and C.ericifolium are very similar to C.taxifolium and, as the ranges of all three species overlap, correct identification can be confusing. C.taxifolium is also reported to hybridise with C.longifolium in the wild, further confusing identification. Very few Conospermum species are in cultivation due to difficulties in propagation. Some forms of C.taxifolium are seen in gardens from time to time and are best grown in a sunny, or slightly shaded position in well drained soils. Although not a spectacular species, this is an unusual and interesting plant when in flower. Although some success has been achieved in seed propagation, germination can be very unreliable. Cuttings of firm, current season's growth are reported to strike reasonably well with some forms but can be difficult and slow with others..

For your Diary 3 The Department of Environment and Science oversees a large Bonni’s Wallum Garden plantation area between Caboolture and Caloundra, and to the west. Due to the foresight of some far-sighted foresters back in at Nerang 4 the 1930s and 1940s, sections of native forest were set aside as More on Bonni’s Garden 5 the pine forests were established. After the Forestry Act of 1959 Vale Betty Sykes 5 was passed, there was provision for such sections to become Quote 6 "Scientific Areas", to be used for scientific purposes, other than Wallum Hotspot 6 pine plantations. Reminders 6 Being the first such area officially declared in Queensland after 1959, the Beerwah section was therefore named "Beerwah State Forest Scientific Area No. 1". Since then it has been gazetted as a National Park. It is divided into blocks of varying size, which are burnt at different intervals and times according to season and weather.

Ecology of Proteaceae with Special Reference to the Sydney Region
951 Ecology of Proteaceae with special reference to the Sydney region P.J. Myerscough, R.J. Whelan and R.A. 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.

Spatial analysis of risks posed by root rot pathogen, Phytophthora cinnamomi: implications for disease management. Proceedings of the Linnean Society of New South Wales 134, B147-B179. Phytophthora cinnamomi, a soil-borne pathogen that infects the roots of plants, is listed as a Key Threatening Process under Commonwealth and NSW state biodiversity legislation due to its deleterious effects on native ﬂ ora. In warm temperate eastern Australia, the disease may cause insidious declines in plant species that have slow rates of population turnover, and thereby threaten their long term persistence. Phytophthora cinnamomi has been known to occur in Royal National Park since the 1970s and systematic surveys for the pathogen were carried out a decade ago. Development of effective management strategies to mitigate the impacts of the disease requires information on the spatial distribution of risks posed by the disease. In this study, we use limited disease survey data to identify areas that are most at risk. We propose and apply a simple risk model in which risks of disease impact are proportional to the product of habitat suitability for the pathogen and abundance of susceptible biota.

Best Local Native Plants for Use in Bushfire Prone Locations
Best local native plants for use in Bushfire Prone Locations In the wake of bushfire, many local gardeners seek to replant landscaped areas with so called ‘low flammability’ species. It is important to understand that under extreme bushfire conditions, all vegetative material can burn. However, some species are less likely to ignite or burn intensely than others, and some species have growth characteristics which make them less likely to promote the spread of fire. If you are replanting the areas surrounding your dwelling or other areas within your Asset Protection Zone (APZ), careful attention must be paid to both species selection and garden layout. Consider the usefulness and suitability of each existing or proposed planting. Be mindful of the plant’s ultimate height and spread, and don’t overplant, or alternatively be prepared to prune or cull as plants mature. Both vertical and horizontal separation between canopy components or shrub clusters needs to be retained so as to reduce the potential for fire to spread. Whether selecting new plants for your garden, or species for retention in your APZ, there are a few key characteristics to look for: • Relatively high moisture content of leaves (‘mesic’ or rainforest type species, but these need to remain well watered if they are to retain their fire suppressant characteristics) • Low levels of volatile oil in leaves (crush and sniff the leaf to see if you can detect a strong smell) • Large or hard leaves with simple margins • Smooth, hard, or persistent bark, rather than flakey or ribbon bark • Plants that don’t accumulate a lot of dead leaf and stem material below them or suspended in the foliage.

Wednesday Walk – Touga Road Crawl – 29 August 2012
Wednesday Walk – Touga Road Crawl – 29 August 2012 We drove from Bungendore via Tarago and Oallen Ford to the Nerriga Road, then headed east across the Endrick River and through Bulee Gap, turning left onto Touga Road where we immediately stopped for morning tea. It was very rewarding with a lot of colour. We overlooked many of the plants that were so stunning last October because they weren't yet out. Instead, we had a whole new range of early flowers - Acacia elongata, A. ulicifolia, Banksia ericifolia, B. spinulosa, Hakea sericea, Leucopogon ericoides, Boronia algida, B. rigens, Bossiaea kiamensis, Dampiera stricta, Dillwynia ramosissima, Cryptandra amara var. floribunda, Pomaderris ? andromedifolia, P. lanigera, Grevillea baueri ssp. asperula, G. patulifoia. Other plants we put names to that weren't flowering included Banksia paludosa, Isopogon anethifolius, Petrophile sessilis, Lomandra obliqua, Caustis flexuosa, Leptospermum rotundifolium, Aotus ericoides, Kunzea parvifolia, Calytrix tetragona, Allocasuarina distyla, Persoonia mollis, P. levis and many more species. We then went about 7km to The Jumps and explored the rock shelves and had lunch. Many of the plants were the same but we added a few more species which were flowering - Acacia hamiltoniana, Conospermum taxifolium, Hibbertia monogyna, Philotheca scabra, Epacris calvertiana, Phyllota phylicoides and also saw some very nice mallee-type trees – Eucalyptus stricta. We then drove up The Jumps to a higher plateau and explored some more rocky platforms which had many of the same plants already seen but we added Mirbelia platylobioides, Boronia anemonifolia, Actinotus minor, Olax stricta, Tetratheca thymifolia, Goodenia heterophylla, Patersonia glabrata. On the way back on Touga Rd, we stopped to check some Pomaderris andromedifolia thickets and found a few in flower.

Bernhardt1,2, G.R. Camilo1 & P.H. Weston2 1Department of Biology, Saint Louis University, 3507 Laclede Avenue, St Louis, MO 63103-2010 USA. [email protected] 2National Herbarium of New South Wales, Royal Botanic Garden, Mrs Macquaries Road,Sydney NSW 2000, Australia. ABSTRACT. Sympatric populations of Symphionema montanum R.Br. and Isopogon anemonifolius (Salisb.) Knight showed overlapping flowering periods during November 2009 in the Blue Mountains (New South Wales, Australia). Symphionema montanum has porose anthers encircling the protruding style, and lacks a pollen presenter. In contrast, sessile, longitudinally dehiscent anthers of Isopogon anemonifolius deposit pollen grains on the subterminus of the style (pollen presenter). Neither species secretes nectar. The majority of foragers on Symphionema montanum were polylectic, female bees (Halictidae). Their pollen foraging resembled sonication and shaking. Polylectic, female bees (Colletidae) were dominant foragers on Isopogon anemonifolius grasping styles with their mandibles while scraping the pollen presenter. Exoneura species (Apidae) visited both shrubs. Only two specimens of Callomelitta antipodes on Isopogon anemonifolius carried pollen of both shrub species. Most bees, collected on either shrub, carried the grains of their host mixed with one to six pollen morphotypes of co-blooming, nectariferous taxa. We report a positive correlation between an increase in bee size and the number of morphotypes carried but colletids of Isopogon anemonifolius carried fewer morphotypes than halictids on Symphionema montanum.
