Senecio adonidifolius, S. aquaticus, S. boissieri, S. flavus, S. gallicus, S leucophyllus, S. malacitanus, and S. minutus are lectotypified, and an epitype is designated for S. aquaticus.

We had a week of mostly pleasant sunny weather with only one or two spells of rain, but this did not stop us from visiting any of the important habitats. We started on the flat coastal area north of Bari, visiting some salt pans and a deserted beach where we had some excellent birdwatching and found a few unusual coastal plants, and then headed into the hills for the rest of our stay. Our base in the historic hill-top town of Monte Sant’Angelo enabled us to reach some superb orchid habitats, and we also had time to check out the grassy slopes behind the hotel, and explore the town itself, a UNESCO World Heritage Site. The latter part of the week was spent in the charming seaside town of Peschici, in the family-run Hotel Elisa located on the harbour.

    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups.

I view Professor Abbott as an international leader in the areas of plant hybridization and phylogeography. His work is notable for its high quality, thoroughness, and careful and nuanced interpretations of results. Also, included in this nomination package is a letter of support from Corresponding Member Dianne Edwards CBE FRS, who is a Distinguished Research Professor at Cardiff University, along with Richard’s CV. Below I highlight several of Prof. Abbott’s most important contributions, as well as the characteristics of his work that I particularly admire. Prof. Abbott is probably best known for his careful elucidation of the reticulate history of Senecio (ragworts and groundsels) of the British Isles. His studies of the Senecio system have combined careful analyses of historical plant distribution records in the UK, with data from ecological experiments, developmental genetics, and population genetic and genomic analyses. This multidisciplinary approach is powerful, and Prof. Abbot’s work has revealed several examples of plant speciation in real time (and there aren’t very many of these). Key findings include (1) the discovery and careful documentation of the homoploid hybrid origin of the Oxford

    Journal of Phytology 2010, 2(1): 034–040 ISSN: 2075-6240 © Journal of Phytology, 2010 Available Online: www.journal-phytology.com REGULAR ARTICLE PHYTOCHEMICAL SCREENING AND MINERAL CONTENTS OF ANNUAL PLANTS GROWING WILD IN THE SOUTHERN OF TUNISIA Ahmed Akrout*, Hajer El Jani, Tarek Zammouri, Hédi Mighri, Mohamed Neffati Laboratoire d’écologie pastorale, Institut des Régions Arides, Km 23, Route El Jorf, 4119 Médenine, Tunisia SUMMARY Eight annual species growing wild in the southern of Tunisia (Diplotaxis simplex, Chrysanthemum coronarium, Matthiola longipetela, Erodium glaucophyllum, Reseda alba, Diplotaxis harra, Senecio gallicus and Papaver rhoeas) were evaluated for their mineral contents and phytochemical screening. The mineral analysis showed that calcium and potassium were the most concentrated minerals (1.21-3.60% and 0.36-3.20% respectively) followed by sodium (0.12-1.38%), magnesium (0.16-0.41%) and phosphorus (0.05-28%). The preliminary phytochemical screening revealed the absence of anthraquinones in all studied plants whereas alkaloids were only present in Papaver rhoeas. Senecio gallicus and Chrysanthemum coronarium were the only species that contained essential oils. All species were found to contain saponins, flavonoids and tannins with the exception of Erodium glaucophyllum and Papaver rhoeas. These results indicate that some of these species may be used as fodder plants for livestock due to their high contents of minerals but the presence of some secondary metabolites may reduce their palatability. In the other hand, these secondary metabolites could be the origin of the medicinal properties of these species. Keywords: Phytochemical screening, Tunisian annual plants, Mineral contents.

    The Status of Asteraceae in the Arid and Saharan Flora of North African Region: Case of Tunisia

    Pak. J. Bot., 42(3): 1417-1422, 2010. THE STATUS OF ASTERACEAE IN THE ARID AND SAHARAN FLORA OF NORTH AFRICAN REGION: CASE OF TUNISIA ZOUHEIR NOUMI*, SAAD OULED DHAOU, SALMA DERBEL AND MOHAMED CHAIEB Department of Biology, U.R. Biology & Ecophysiology of Plants, Science Faculty of Sfax Tunisia 3018, BP 802. Abstract In North Africa, mainly in Tunisia, the family of Asteraceae is largely represented by a number of species, since in the center and in the south of the country, the number of species is more than 172 species with 13.5% of the whole of the flora of Phanerogames in the center and the south of country. This study consists of an analysis of the botanical importance of the Asteraceae family in the southern Tunisia flora, in particular its generic composition, the biological types and the phytochoric status, which characterize this flora. The analysis shows that the Therophytes are the most abundant in Tunisia. On the other hand, the Geophytes are represented within the family of Asteraceae. The relation between Asteraceae present in Tunisia and their phytogeographical origin shows that the origin of the totality of the species is the Mediterranean circumference region. The taxons with North African origin are on the other hand slightly represented. Moreover, in spite of the abundance of the species within the family of Asteraceae, 10 genera most representative of Asteraceae are inventoried in the south of Tunisia. The genus Centaurea includes only 8% of the Asteraceae present in the South of Tunisia, followed by the genera of Atractylis and Senecio with 5% of species.

Eleven pyrrolizidine alkaloids were identified and their content was evaluated by GLC-MS and GLC analysis. Otosenine and florosenine were found to be the major alkaloids in all studied species. It is interesting that only S. ambi- guus subsp. nebrodensis was characterized by a high content of the alkaloids jacobine, jaco- line, jaconine, and jacozine.

HARRIS Department of Plant Sciences, University of Oxford, South Parks Road, Oxford OX1 2RB* ABSTRACT The introduction of Senecio squalidus L. (Asteraceae) to Oxford, from Sicily, in the late 17th century and its subsequent spread through the United Kingdom, via the railway lines, is one of the best-documented introductions. Evidence for the introduction of S. squalidus to the Oxford Botanic Garden has come from herbarium and literature records, but despite the conclusions of previous investigators, there is no evidence from dated sources showing that S. squalidus was growing in the British Isles before 1700. Furthermore, evidence for an initial introduction to Oxford is limited, although if the records cited by George Druce are correct then it is likely that S. chrysanthemifolius, rather than S. squalidus was the initial introduction. Specimen-based evidence suggests that a more likely initial route of S. squalidus introduction was via Francisco Cupani and William Sherard (probably between 1700 and 1702), to the Duchess of Beaufort’s garden at Badminton, with a later transfer of material to Oxford before Jacob Bobart’s death in 1719. KEYWORDS: Species introduction, Compositae, botanical history. INTRODUCTION The introduction of Senecio squalidus L. (Asteraceae) to the Oxford Botanic Garden from Sicily in the late 17th century and its subsequent spread through the United Kingdom via the railway lines has caught the imagination of generations of British naturalists, horticulturists and botanists (Druce 1927b; Kent 1956).
