What Is a Tree in the Mediterranean Basin Hotspot? a Critical Analysis
Médail et al. Forest Ecosystems (2019) 6:17 https://doi.org/10.1186/s40663-019-0170-6 RESEARCH Open Access What is a tree in the Mediterranean Basin hotspot? A critical analysis Frédéric Médail1* , Anne-Christine Monnet1, Daniel Pavon1, Toni Nikolic2, Panayotis Dimopoulos3, Gianluigi Bacchetta4, Juan Arroyo5, Zoltán Barina6, Marwan Cheikh Albassatneh7, Gianniantonio Domina8, Bruno Fady9, Vlado Matevski10, Stephen Mifsud11 and Agathe Leriche1 Abstract Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-European region (from Portugal to Cyprus). We identified some cases of woody species difficult to categorize as trees that we further called “cryptic trees”. We collected the occurrences of tree taxa by “administrative regions”, i.e. country or large island, and by biogeographical provinces. We studied the species-area relationship, and evaluated the conservation issues for threatened taxa following IUCN criteria. Results: We identified 245 tree taxa that included 210 species and 35 subspecies, belonging to 33 families and 64 genera. It included 46 endemic tree taxa (30 species and 16 subspecies), mainly distributed within a single biogeographical unit. -

Schweickerdt Herbarium, Department of Plant Science, University of Pretoria, Pretoria, 0002 South Africa. Abstract A new species of Polygala (Polygalaceae), P. retiefiana, is described from the KwaZulu-Natal and Free State provinces of South Africa. It is endemic to the country. Key words: plant taxonomy, biodiversity, Polygalaceae, Polygala retiefiana, endemic, South Africa With the order Polygalales no longer accepted, the Polygalaceae belong now to the order Fabales, the circumscription of which (Chase et al. 1993) includes four families: Fabaceae, Polygalaceae, Quillajaceae and Saurianaceae. These families have as common characteristic the monosymmetric flowers (Tucker 2003) where one of the petals, or two united petals, form a keel (carina) which covers the androecium and gynoecium. This group of plants with papilionaceous or pseudo-papilionaceous flowers is well-characterised both molecularly (APG III 2009) and ontogenically (Bello et al. 2010). Interfamilial relationships and patterns of floral evolution were also found between these four families (Bello et al. -
Outline of Angiosperm Phylogeny
Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

Handa) Abstract To diversify flower color and growth habit of marguerite (Argyranthemum frutescens), intergeneric crossing was carried out using marguerite as the seed parent and annual chrysanthemum (Glebionis carinatum) or crown daisy (G. coronaria) as the pollen parent. After cross-pollination, seedlings were successfully obtained by applying ovule culture. Ovule culture-derived plants showed novel characteristics in flower shape and color (orange, reddish brown, or wisteria pink) that are not observed in marguerite. Some also showed novel flowering habits such as perpetual flowering. The results indicate that these ovule culture-derived plants were intergeneric hybrids and that the hybrids obtained in the present study may be useful for further breeding of marguerite, especially for introducing valuable characteristics such as a wide range of flower color. Key words: Argyranthemum, Glebionis, intergeneric hybridization, ovule culture. Marguerite (Argyranthemum frutescens) is a perennial germplasm for the breeding of marguerite, but most of plant native to the Canary Islands, Spain (Bramwell et them have white flowers and diversity in flower color and al. 2001) and Madeira, Portugal (Press et al. -

Plant Life of Western Australia
INTRODUCTION The characteristic features of the vegetation of Australia I. General Physiography At present the animals and plants of Australia are isolated from the rest of the world, except by way of the Torres Straits to New Guinea and southeast Asia. Even here adverse climatic conditions restrict or make it impossible for migration. Over a long period this isolation has meant that even what was common to the floras of the southern Asiatic Archipelago and Australia has become restricted to small areas. This resulted in an ever increasing divergence. As a consequence, Australia is a true island continent, with its own peculiar flora and fauna. As in southern Africa, Australia is largely an extensive plateau, although at a lower elevation. As in Africa too, the plateau increases gradually in height towards the east, culminating in a high ridge from which the land then drops steeply to a narrow coastal plain crossed by short rivers. On the west coast the plateau is only 00-00 m in height but there is usually an abrupt descent to the narrow coastal region. The plateau drops towards the center, and the major rivers flow into this depression. Fed from the high eastern margin of the plateau, these rivers run through low rainfall areas to the sea. While the tropical northern region is characterized by a wet summer and dry win- ter, the actual amount of rain is determined by additional factors. On the mountainous east coast the rainfall is high, while it diminishes with surprising rapidity towards the interior. Thus in New South Wales, the yearly rainfall at the edge of the plateau and the adjacent coast often reaches over 100 cm. -
