Stellenbosch University, of which I have the honour to be Vice-Rector for Research, opens its arms to embrace the largest crowd of vegetation scientists ever to assemble in our country, or anywhere in Africa, for that matter. The University is especially proud to host this, the 51st annual symposium of IAVS, which is one of the oldest and most respected ecological societies in the world. We trust that you will enjoy not only the fantastic flora of the Cape, but also our hospitality, and, of course, our wine. The Cape is special – one of few places on this planet where an appreciation of beautiful plants and fascinating vegetation is not restricted only to professional botanists – as an engineer by training, I am a living proof of this. Coming to the Cape, which is home to the most diverse of the planet’s five floral kingdoms, is a dream of every botanist. Here is a kingdom blessed with unique flora and many floral superstars, such as proteas, pelargoniums, restios, hundreds of ericas, gladioli and many other bulbs – the complete list is much too long to mention here. I gather that most of you attended the pre-symposium excursions to our western and southern coasts, and especially to Namaqualand. At this time of the year these regions are floral wonders that we appreciate tremendously. The beauty of those landscapes is truly addictive. In addition to its beauty, the Cape Floral Kingdom is an unsurpassed laboratory in which we can delve into the secrets of the evolution of plants and vegetation. It therefore is not surprising that the major focus of your meeting is evolution – or rather, bringing together the concepts of vegetation science and evolution. This is the sort of approach that is encouraged in the academic programmes of Stellenbosch University – we place a major emphasis on cutting-edge interdisciplinary and multidisciplinary research. We also encourage and foster international contacts. It is for these two reasons that the University is very pleased to host and support your meeting. I wish you success and relaxation. May you make many new friends and forge many new research partnerships. Simply put – have a good time and enjoy Stellenbosch!

The IAVS is a very active scientific body, organizing usually one (rarely two) general annual meetings, publishing two international journals – Journal of Vegetation Science and Applied Vegetation Science – until 2008 in cooperation with Opulus Press, Uppsala, Sweden (www.opuluspress.se) and from 2009 onwards in cooperation with the renowned international publishing house Wiley-Blackwell, Oxford, UK (www.blackwell.org). IAVS also supports several sub-units (regional sections) which pursue the aims of the IAVS on a regional level and in specialised working groups. After having held most of the past meetings in the Northern Hemisphere, the IAVS will hold its annual meeting for the first time in Africa. Focus of the Symposium http://sun.ac.za/iavs2008/ The main focus of the symposium is to seek links between vegetation science

    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. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.

  • Floristic-Phytosociological Approach, Potential Natural Vegetation, and Survival of Prejudice

Floristic-phytosociological approach, potential natural vegetation, and survival of prejudice. Lazaroa 31: 173-182 (2010). Carrión & Fernandez (2009; further C&F) in a recent commentary on a paper published in Journal of Biogeography criticised an obvious mismatch between the predictions about the patterns of potential natural vegetation (PNV) made by phytosociologists, and those underpinned by pollen data. C&F used this stage to take a broad sway on phytosociology in general (stopping only very short of denying it status of science), blaming power of tradition and influence of personal cult for ignoring scientific evidence. In my response I show that C&F have misinterpreted the concept of PNV, rendering their comparisons irrelevant. C&F obviously overslept the progress descriptive vegetation science made in recent decades, relegating their heavy criticism of phytosociology into the realm of prejudice. Keywords: descriptive vegetation science, phytosociology, personality, potential natural vegetation, reconstructed natural vegetation, Spain, vegetation mapping Resumen: Mucina, L. 2010. Supervivencia de prejuicios en el concepto de vegetación potencial natural, y en las aproxi- maciones florística-fitosociológica. Lazaroa 31: 173-182 (2010). Carrión y Fernández (2009; C&F) en un comentario recientemente publicado en Journal of Biogeography han criticado la falta de relación entre las predicciones que sobre modelos de vegetación natural potencial (PNV) han hecho los fitoso- ciólogos, y aquellas sostenidas por datos polínicos, utilizando este hecho para hacer una crítica amplia y general de la fi- tosociología, negándola, aunque de forma breve, el estatus de ciencia.

    Polish Botanical Journal 60(2): 147–161, 2015 DOI: 10.1515/pbj-2015-0024 PHYTOGEOGRAPHICAL ANALYSIS OF EUPHORBIA SUBGENUS ESULA (EUPHORBIACEAE) Dmitry V. Geltman Abstract. Euphorbia subg. Esula is one of four major clades within the genus. A geographical analysis of the 466 species in the subgenus is reported here. Every species was assigned to one of 29 geographical elements clustered in ten groups of ele- ments. This geographical analysis showed that the Tethyan group (comprising nine geographical elements) clearly dominates the subgenus and contains 260 species (55.79% of the total number of species). The most numerous geographical elements are Irano-Turanian (105 species) and Mediterranean (85). Other significant groups of elements are Boreal (91 species, 19.54%), East Asian (40 species, 8.58%), Madrean (26 species, 5.58%), Paleotropical (23 species, 4.94%) and South African (16 species, 3.43%). The area of the Tethyan floristic subkingdom is the center of the modern diversity of E. subg. Esula. It is likely that such diversity is the result of intensive speciation that took place during the Eocene–Miocene. Key words: Euphorbia subg.

  • Chapter 3 MATERIAL and METHODS
    Chapter 3 MATERIAL AND METHODS 3.1. Introduction The study of flora consists of plant and situation of plant habitat. There are many definitions for word "flora". The word "flora" refers to the plants occurring within a given region. A Flora may contain anything from a simple list of the plants occurring in an area to a very detailed account of those plants. Floras are different from popular manuals in that they attempt to cover all of the plants, rather than only the most common or conspicuous ones. When a researcher wants to study Flora he/or she can understand many things from that. A Flora ahnost always contains scientific names, and it may also include common names, literature references, descriptions, habitats, geographical distribution, illustrations, flowering times, and notes. Less often, Floras includes such specialized information as data on plant chemistry, reproduction, chromosome numbers, and population occurrences. Sometimes, the plants are listed alphabetically, and sometimes they are represented within a classification system that indicates which plants are most similar or are thought to be related. Floras often also include devices called "keys" that enable the user to identify an unknown plant. Floristic elements are most often defined subjectively by grouping plant ranges into types based on descriptions provided by floras and manuals (McLaughlin and Bowers, 1990). By study of floristic traits of an area, it is possible to describe floristic province and phytogeographical regions. The delimitation of floristic provinces and sub-provinces is mainly based on the distribution boundaries of vascular plant species (Yurtsev, 1994) which is known as true plants.

    Polish Botanical Journal 57(1): 109–118, 2012 PHYTOGEOGRAPHICAL AND ECOLOGICAL AFFINITIES OF THE BRYOFLORISTIC REGIONS OF SOUTHERN AFRICA 1 JACQUES VAN ROOY & ABRAHAM E. VAN WYK Abstract. There is a high degree of correspondence between the bryofl oristic regions of southern Africa and phytochoria based on the distribution of seed plants, especially those of White and Linder. The bryofl oristic classifi cation provides evidence for a greater Afromontane Region that includes the Cape Floristic as well as the Maputaland-Pondoland Regions, but excludes the Afro-alpine Region. Recent numerical classifi cations of the region do not support a Greater Cape Floristic Region or Kingdom, but reveal the existence of a broad-scale temperate (Afrotemperate) phytochorion consisting of the Kalahari-Highveld and Karoo- Namib Regions. Endemism is much lower in the moss than the seed plant fl oras of congruent phytogeographical regions. The bryofl oristic regions correspond in varying degrees with the biomes and vegetation types of southern Africa.

  • Speciation Environments and Centres of Species Diversity in Southern Africa: 2
    Bothalia 14, 3 & 4: 1007-1012 (1983) Speciation environments and centres of species diversity in southern Africa: 2. Case studies G. E. GIBBS RUSSELL* and E. R. ROBINSON** ABSTRACT Distributions of species in the grass genera Cymbopogon, Digitaria, Ehrharta and Stipagrostis are mapped to show that speciation within the phytochorion, where a genus has undergone major adaptive radiation (‘phytochorial sympatry’), may be differentiated from speciation in a phytochorion outside this characteristic one (‘phytochorial allopatry’). Testing of this hypothesis seems a fruitful field for systematists and will enhance our understanding of the flora. RÉSUMÉ MILIEUX DE SPÉCIATION ET CENTRES DE DIVERSITÉ DES ESPÊCES EN AFRIQUE DU SUD. 2. ETUDES PARTICULIËRES. Les répartitions geographiques des espêces dans les quatre genres de graminées, Cymbopogon, Digitaria, Ehrharta et Stipagrostis, sont cartographiées pour montrer que la spéciation au sein de la phytochorie ou un genre a connu une diversification évolutive importante ('sympatrie phytochoriale'), peut être différenciée de la spéciation au sein d’une phytochorie qui ne présente pas cette caractéristique (‘allopatrie phytochoriale’). La vérification de cette hypothêse semble offrir un fructueux champ de recherches pour les systématiciens et améliorera notre connaissance de la flore.

En este trabajo se describe un nuevo orden (Asplenietalia septentrionalo-cuneifolii) y dos nuevas alianzas (Arenarion bertolonii and Physoplexido comosae- Saxifragion petraeae) dentro de Asplenietea. Además Asplenietalia lanceolato-obo- vati es formalmente propuesto como orden y el nombre Hypno-Polypodietalia vulgaris es validado. Palabras clave: alianza, Asplenietea trichomanis, vegetación casmofítica, orden, fitosociología, Polypodietea, Alpes del sur, sintaxonomía, validación, oeste de Europa. INTRODUCTION This paper was motivated by the synthetic assessment of the European vegetation to be Although the European chasmophytic (rock- shortly published as the EuroVegChecklist crevice) vegetation of the Asplenietea trichomanis (Mucina & al., submitted) and should serve to and the Polypodietea does not occupy large solve several nomenclatural and syntaxonomic areas, it is yet one of the most diverse vegetation issues in the Asplenietea trichomanis.

PhytoKeys 78: 83–107. https://doi.org/10.3897/phytokeys.78.12040 Abstract The monotypic fern genusDryopolystichum Copel. combines a unique assortment of characters that ob- scures its relationship to other ferns. Its thin-walled sporangium with a vertical and interrupted annulus, round sorus with peltate indusium, and petiole with several vascular bundles place it in suborder Poly- podiineae, but more precise placement has eluded previous authors. Here we investigate its phylogenetic position using three plastid DNA markers, rbcL, rps4-trnS, and trnL-F, and a broad sampling of Polypodi- ineae.
