Plant of the Month - January by Allan Carr Hibbertia scandens Twining Guinea Flower Pronunciation: he-BERT-ee-a SCAN-dens DILLENIACEAE Derivation: Hibbertia, after George Hibbert, 1757-1837 English merchant, politician, slave owner, ship owner and botany patron; scandens, from the Latin, scandere – to climb. Flower Fruit showing bright orange arils Hibbertia is a large genus of more than 150 species, the majority of them being endemic in Australia, particularly in WA where about 68 species are found. Most species are found among the low shrubs of heathlands and sandplain vegetation and a significant proportion also grow in open forest and woodland. Overseas they are also found in New Guinea, New Caledonia, Fiji and Madagascar. Description: H. scandens is a vigorous trailing or climbing vine with stems to 4 metres. These plants are found on the coast and ranges from central Queensland to south-eastern New South Wales. H. scandens was named the ‘Guinea Flower’ by early settlers, as its colour was likened to the golden guinea coin that was used at that time. Leaves are alternate and elliptical in shape to about 80 mm by 30 mm. The upper surface is glossy and deep green in colour, while the lower surface is finely hairy. Plants near the sea tend to have leaves rounded at the *apex as in the photos above while inland plants tend to have leaves with a tapering apex. Flowers, large and golden yellow, 50 to 70 mm across, occur throughout the year but are most commonly seen from August to January. The individual flowers with five petals usually last only a day or two but new flowers are produced over a long period. Fruits are capsules to 12 mm, opening to reveal bright orange *arils around brownish seeds. *apex = the tip (opposite end from the stem) *aril = a fleshy outgrowth of the stalk of a seed, often succulent and/ or brightly coloured and bird or insect attracting Habit .

Post-Fire Recovery of Woody Plants in the New England Tableland Bioregion
Post-fire recovery of woody plants in the New England Tableland Bioregion Peter J. ClarkeA, Kirsten J. E. Knox, Monica L. Campbell and Lachlan M. Copeland Botany, School of Environmental and Rural Sciences, University of New England, Armidale, NSW 2351, AUSTRALIA. ACorresponding author; email: [email protected] Abstract: The resprouting response of plant species to fire is a key life history trait that has profound effects on post-fire population dynamics and community composition. This study documents the post-fire response (resprouting and maturation times) of woody species in six contrasting formations in the New England Tableland Bioregion of eastern Australia. Rainforest had the highest proportion of resprouting woody taxa and rocky outcrops had the lowest. Surprisingly, no significant difference in the median maturation length was found among habitats, but the communities varied in the range of maturation times. Within these communities, seedlings of species killed by fire, mature faster than seedlings of species that resprout. The slowest maturing species were those that have canopy held seed banks and were killed by fire, and these were used as indicator species to examine fire immaturity risk. Finally, we examine whether current fire management immaturity thresholds appear to be appropriate for these communities and find they need to be amended. Cunninghamia (2009) 11(2): 221–239 Introduction Maturation times of new recruits for those plants killed by fire is also a critical biological variable in the context of fire Fire is a pervasive ecological factor that influences the regimes because this time sets the lower limit for fire intervals evolution, distribution and abundance of woody plants that can cause local population decline or extirpation (Keith (Whelan 1995; Bond & van Wilgen 1996; Bradstock et al.

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.

Floral Presentation Contributes to Pollinator Guild Segregation in Co-Blooming Symphionema Montanum and Isopogon Anemonifolius (Proteaceae)
Gardens' Bulletin Singapore 71 (2): 377–396. 2019 377 doi: 10.26492/gbs71(2).2019-05 Shaken vs scraped: floral presentation contributes to pollinator guild segregation in co-blooming Symphionema montanum and Isopogon anemonifolius (Proteaceae) P. 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.
