With a changing climate, shrub encroachment may rely on recruitment from seed occurring outside of the optimum temperature range. We used a temperature gradient plate in order to determine the germination niche of 14 alpine shrub species. We then related the range in laboratory germination temperatures of each species to long-term average temperature conditions at: (1) the location of the seed accession site and (2) across each species geographic distribution. Seven of the species failed to germinate sufficiently to be included in the analyses. For the other species, the germination niche was broad, spanning a range in temperatures of up to 17 ◦C, despite very low germination rates in some species. Temperatures associated with the highest germination percentages were all above the range of temperatures present at each specific seed accession site. Optimum germination temperatures were consistently within or Citation: Venn, S.E.; Gallagher, R.V.; higher than the range of maximum temperatures modelled across the species’ geographic distribution.

A phylogeny of Solanaceae is presented based on the chloroplast DNA regions ndhF and trnLF. With 89 genera and 190 species included, this represents a nearly comprehensive genus-level sampling and provides a framework phylogeny for the entire family that helps integrate many previously-published phylogenetic studies within So- lanaceae. The four genera comprising the family Goetzeaceae and the monotypic families Duckeodendraceae, Nolanaceae, and Sclerophylaceae, often recognized in traditional classifications, are shown to be included in Solanaceae. The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive “x = 12” clade, which includes Nicotiana and the Australian tribe Anthocercideae. These results also provide greater resolution among lineages within Solanoideae, confirming Jaltomata as sister to Solanum and identifying a clade comprised primarily of tribes Capsiceae (Capsicum and Lycianthes) and Physaleae.
  • Boxthorn Lycium Ferocissimum

    Boxthorn Lycium Ferocissimum

    Boxthorn Lycium ferocissimum Family Solanaceae (nightshade) Also known as African boxthorn Where is it originally from? South Africa What does it look like? Densely branched, erect, evergreen shrub (<6 m tall) with tough, woody stems alternately branched at square angles, forming a box- like pattern, and with rigid spines (13 mm). Hairless, fleshy, bright green leaves (40 x 12 mm) are narrow, oblong and clustered along the stems. White to pale mauve flowers (10-13 mm) produced from July to March are followed by tear shaped orange red berries (5-12 mm) in autumn. Photo: Carolyn Lewis Are there any similar species? Hawthorn and barberry are similar. Lycium barbarum (L. chinense) is similar but is deciduous. Why is it weedy? Forms dense, tall, long-lived stands, excluding most other vegetation. Tolerates a wide variety of soil types (sand to rocky cliffs), drought, salt, wind, and hot to cold temperatures. Poisonous (usually not grazed). How does it spread? Birds and possibly possums. Common seed sources are farm hedges, roadsides, waste places. Photo: Carolyn Lewis What damage does it do? Overtops native plants and can become only woody plant species on site. Petrels and other seabirds can become entangled and die. Berries may poison birds. Which habitats is it likely to invade? Sand dunes, shrublands, cliffs, islands and other coastal areas, gravel, and roadsides. What can I do to get rid of it? 1. Hand pull seedlings, winch out larger plants (all year round): Plant material can be left on site. 2. Stump swab (all year round): glyphosate (200ml/L) or a product containing 100g picloram+300g triclopyr/L (200ml/L).

    The Pastoral History, Biological and Cultural Signifi cance of the Scotia Country, far Western New South Wales MARTIN WESTBROOKE Centre for Environmental Management, University of Ballarat, Mt Helen, Victoria 3353 ([email protected]) Published on 28 August 2012 at http://escholarship.library.usyd.edu.au/journals/index.php/LIN Westbrooke, M. (2012). The pastoral history, biological and cultural signifi cance of the Scotia Country, far western New South Wales. Proceedings of the Linnean Society of New South Wales 134, A55-A68. The Scotia country of far western New South Wales, once part of the vast Lake Victoria lease and subsequently split into six smaller properties after WW1, has one of the shortest grazing histories in the state. The low stocking rates due to unsuitable feed provided by the mallee vegetation and limited water supplies have left native vegetation communities relatively intact and close to original condition. A natural salt lake system with rare plants and plant communities adds to the values of the area. This paper reviews the pastoral history of the area and the features which make the Scotia of outstanding conservation and cultural signifi cance. Manuscript received 19 October 2011, accepted for publication 11 January 2012. KEYWORDS: conservation, cultural, mallee, pastoral lease, plant communities, Scotia.

Nanya Homestead complex 2 BACKGROUND The Scotia region has one of the shortest stock grazing histories of western NSW. Along with five other properties, Nanya was created as a pastoral lease in 1927. Previously the area was part of the large Lake Victoria lease and stock grazing occurred only in wet years (Withers 1989). The original lease was taken up by Gordon Cummings in 1927. He first dug a dam near the southeast corner of the property. A larger ground tank and homestead at the site of the present complex was later established. An area around the homestead was cleared and cropped to provide feed for the horses used in digging the earth tanks. The ruins of the original building are located between the shearing shed and Homestead Tank.
