Conservation Advice Muehlenbeckia Tuggeranong
THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister’s delegate approved this conservation advice on 01/10/2015 Conservation Advice Muehlenbeckia tuggeranong Tuggeranong lignum Conservation Status Muehlenbeckia tuggeranong (Tuggeranong lignum) is listed as Endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act). The species is eligible for listing as Endangered as, prior to the commencement of the EPBC Act, it was listed as Endangered under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). The main factors that are the cause of the species being eligible for listing in the Endangered category are its small population size with a very low total number of mature individuals, and restricted area of occupancy. Description The Tuggeranong lignum is a sprawling, scarcely woody shrub with branches growing to approximately 80 cm long. It can develop into a loose tangled mound of wiry stems, growing to 1 metre high and 1-2 metres across (Makinson and Mallison, 1997; Mallinson et al., 1998). Distribution The Tuggeranong lignum is known from the flood terraces on the eastern bank of the Murrumbidgee River south of Canberra (Makinson and Mallinson 1997). The site is near Pine Island, which occurs in the Murrumbidgee River Corridor (Mallinson et al., 1998). When described in 1997, only one female plant and six male plants were known in Pine Island Reserve. In 1999, a seventh male plant was discovered nearby at Red Rocks Gorge (SPRAT, 2015; ESDD, 2013). Propagated plants have been planted in five suitable areas along the eastern river bank within Pine Island Reserve (ESDD, 2013).

The Japanese Knotweed Invasion Viewed As a Vast Unintentional Hybridisation Experiment
Heredity (2013) 110, 105–110 & 2013 Macmillan Publishers Limited All rights reserved 0018-067X/13 www.nature.com/hdy ORIGINAL ARTICLE The Japanese knotweed invasion viewed as a vast unintentional hybridisation experiment J Bailey Chromosome counts of plants grown from open-pollinated seed from Japanese knotweed around the world have revealed the presence of extensive hybridisation with both native and other introduced taxa. These hybrids fit into three categories: inter- and intraspecific hybrids involving the taxa of Fallopia section Reynoutria (giant knotweeds), hybrids between Japanese knotweed and F. baldschuanica (Regel) Holub and hybrids between Japanese knotweed and the Australasian endemics of the genus Muehlenbeckia. In this minireview, the viability of the different classes of hybrid and the potential threats they pose are discussed in the context of recent examples of allopolyploid speciation, which generally involve hybridisation between a native and an alien species. Such wide hybridisations also challenge accepted taxonomic classifications. Japanese knotweed s.l. provides a fascinating example of the interplay between ploidy level, hybridisation and alien plant invasion. The octoploid (2n ¼ 88) Fallopia japonica var. japonica (Houtt.) Ronse Decraene is a single female clone throughout much of its adventive range, and provides an ideal system for investigating the potential for wide hybridisation. Heredity (2013) 110, 105–110; doi:10.1038/hdy.2012.98; published online 5 December 2012 Keywords: Fallopia; gynodioecy; polyploidy; invasive alien plant INTRODUCTION conveniently referred to as Japanese knotweed s.l.Theseareallgiant Although the threat to biodiversity posed by exotic invasive species rhizomatous herbs originating from Asia, they are gynodioecious, has long been recognised, less attention has been paid to the role of with hermaphrodite and male-sterile (female) individuals.

While all non-native alternatives have been screened against several databases to ensure they are not considered weedy, predicting future behaviour is not an exact science! The only way to be 100% sure is to use ecosourced native species. Published by: Weedbusters © 2010 ISBN: 978-0-9582844-7-9 Get rid of a weed, plant me instead! Many of the weedy species that are invading and damaging our natural areas are ornamental plants that have ‘jumped the fence’ from gardens and gone wild. It costs councils, government departments and private landowners millions of dollars, and volunteers and community groups thousands of unpaid hours, to control these weeds every year. This Plant Me Instead booklet profiles the environmental weeds of greatest concern to those in your region who work and volunteer in local parks and reserves, national parks, bush remnants, wetlands and coastal areas.

Approved Conservation Advice for Muehlenbeckia Horrida Subsp. Abdita (Remote Thorny Lignum)
This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Approved Conservation Advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Muehlenbeckia horrida subsp. abdita (Remote Thorny Lignum) This Conservation Advice has been developed based on the best available information at the time this Conservation Advice was approved; this includes existing plans, records or management prescriptions for this species. Following taxonomic revision, the name of this species has changed, and is listed under the EPBC Act as Duma horrida subsp. abdita as at 31 October 2015. Description Muehlenbeckia horrida subsp. abdita, Family Polygonaceae, also known as Remote Thorny Lignum, is a divaricately to intricately branched, spreading erect shrub that grows to a height of 0.6–1.2 m. Flowers are rare, appearing only after plants are inundated, and form in bright, light-yellow clusters with 5 perianth segments. Muehlenbeckia horrida subsp. abdita has fewer perianths, no warty protuberances, a more divaricate and intricate branching habit, fewer leaves at flowering and a less erect habit than M. horrida subsp. horrida (Wilson, 1996). Conservation Status Remote Thorny Lignum is listed as critically endangered. This species is eligible for listing as critically endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as in 2006, the Minister considered the Threatened Species Scientific Committee's (TSSC) advice under section 189 of the EPBC Act and amended the list under section 184 to include Remote Thorny Lignum. The TSSC determined that this species met criteria 1, 2, 3 and 4 of their eligibility criteria (TSSC, 2006b).

This paper includes a standard maximum parsimony (MP) and three-taxon statement analyses (3TA) as well as a taxonomic revision of Polygonum sect. Avicularia subsect. Spinescentia (Polygonaceae) as compared with two closely related taxa: genus Atraphaxis s.s., and genus Bactria. In total, 27 characters, including life history, habit, morphology of the shoots, leaf blades, ocreas, perianth, achene, ultrasculpture of perianth and achene surfaces, as well as pollen morphology, were analyzed, illustrated, and dis- cussed in detail. Both the standard MP and 3TA confirm that monophyletic Polygonum subsect. Spinescentia is sister to the narrowly defined Atraphaxis. The genus Persepolium (Polygonum subsect. Spinescentia), with the circumscription of five species, is established as new to science as a result of this study. Possible transformations of perianth and thyrse morphology are discussed within the framework of the Principle of variable proportions by Troll in connection with a shift of pollination mode in the group of taxa studied.
