A catalogue of all available publications will be issued on request. BOTHALIA Bothalia is named in honour of General Louis Botha, first Premier and Minister of Agriculture of the Union of South Africa. This house journal of the South African National Biodiversity Institute, Pretoria, is devoted to the furtherance of botanical science. The main fields covered are taxonomy, ecology, anatomy and cytology. Two parts of the journal and an index to contents, authors and subjects are published annually. Three booklets of the contents (a) to Vols 1–20, (b) to Vols 21–25, (c) to Vols 26–30, and (d) to Vols 31–37 (2001– 2007) are available. STRELITZIA A series of occasional publications on southern African flora and vegetation, replacing Memoirs of the Botanical Survey of South Africa and Annals of Kirstenbosch Botanic Gardens. MEMOIRS OF THE BOTANICAL SURVEY OF SOUTH AFRICA The memoirs are individual treatises usually of an ecological nature, but sometimes dealing with taxonomy or economic botany. Published: Nos 1–63 (many out of print). Discontinued after No. 63. ANNALS OF KIRSTENBOSCH BOTANIC GARDENS A series devoted to the publication of monographs and major works on southern African flora.Published: Vols 14–19 (earlier volumes published as supplementary volumes to the Journal of South African Botany). Discontinued after Vol. 19. FLOWERING PLANTS OF AFRICA (FPA) This serial presents colour plates of African plants with accompanying text. The plates are prepared mainly by the artists at the South African National Biodiverity Institute. Many botanical artists have contributed to the series, such as Fay Anderson, Peter Bally, Auriol Batten, Gillian Condy, Betty Connell, Stella Gower, Rosemary Holcroft, Kathleen Lansdell, Cythna Letty (over 700 plates), Claire Linder-Smith and Ellaphie Ward-Hilhorst. The Editor is pleased to receive living plants of general interest or of economic value for illustration. From Vol. 55, twenty plates are published at irregular intervals. An index to Vols 1–49 is available. FLORA OF SOUTHERN AFRICA (FSA) A taxonomic treatise on the flora of the Republic of South Africa, Lesotho, Swaziland, Namibia and Botswana. the FSA contains descriptions of families, genera, species, infraspecific taxa, keys to genera and species, syn- onymy, literature and limited specimen citations, as well as taxonomic and ecological notes. Contributions to the FSA also appear in Bothalia. PALAEOFLORA OF SOUTHERN AFRICA A palaeoflora on a pattern comparable to that of the Flora of southern Africa.

According to previous studies, the northern species, present in Europe and the Mediterranean, form a paraphyletic, basal clade, and the southern species, present in South Africa, form a robust monophyletic group. In this work a molecular phylogenetic analysis from European and from Central and South African Erica species was performed using the chloroplast regions: trnL-trnL-trnF and 5´trnK-matK , as well as the nuclear DNA marker ITS, in order i) to state the monophyly of the northern and southern species, ii) to determine the phylogenetic relationships between the species and contrasting them with previous systematic research studies and iii) to compare the results provided from nuclear data and explore possible evolutionary patterns. All species were monophyletic except for the widely spread E. arborea , and E. manipuliflora . The paraphyly of the northern species was also confirmed, but three taxa from Central East Africa were polyphyletic, suggesting different episodes of colonization of this area.

  • Erica Abietina Subsp. Atrorosea | Plantz Africa South African National Biodiversity Institute
    PlantZAfrica - SANBI Erica abietina subsp. atrorosea | Plantz Africa South African National Biodiversity Institute pza.sanbi.org Erica abietina subsp. atrorosea | Plantz Africa Introduction Erica abietina subsp. atrorosea is only found on the Cape Peninsula (endemic Cape Peninsula species) and is known to regular mountain walkers as Erica phylicifolia. When Dr Ted Oliver revised this section of Erica in 2002, he included this species in a complex of seven subspecies within the species abietina. Description Description Erica abietina subsp. atrorosea is a sturdy shrub up to 1 m high. It arises from a single woody stem and branches freely to produce a dense shrub. The mid to upper branches are clothed with a dense arrangement of dark green, needle-like ericoid leaves. This species produces pinkish purple flowers, which are slightly sticky and arranged in attractive clusters near the ends of the branches. The flowers are tubular, curved and widen slightly towards the mouth. Flowers are produced from midsummer to midwinter in the Cape (December to August). Conservation Status Status Printed from: http://www.plantzafrica.com 1 of 3 2017/01/09 12:38 PM PlantZAfrica - SANBI Erica abietina subsp. atrorosea | Plantz Africa South African National Biodiversity Institute Erica abietina subsp. atrorosea is common within conservation areas and so this species has been classified in the Red Data List as Least Concern. A species is listed as Least Concern when it does not qualify for the criteria of Critically Endangered, Endangered, Vulnerable or Near Threatened. Distribution and habitat Distribution description This species is confined to the Cape Peninsula. It is common above Kirstenbosch and on the lower mountain slopes from Constantia Nek southwards to Cape Point.

  • Nectar Distribution and Nectarivorous Bird Foraging Behaviour at Different Spatial Scales
    Nectar distribution and nectarivorous bird foraging behaviour at different spatial scales by Anina Coetzee Dissertation presented for the Degree of Doctor of Philosophy in the Faculty of Science, at Stellenbosch University Supervisor: Prof. Anton Pauw Co-supervisor: Dr. Phoebe Barnard March 2016 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own original work, that I am the authorship owner thereof (unless to the extent explicitly otherwise stated) and that I have not previously in its entirety or in part submitted it for obtaining any qualification. March 2016 Copyright © 2016 Stellenbosch University of Stellenbosch All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract While foraging strategies of animals may be shaped by the distribution of their food resources, these strategies in turn also affect the ecology and evolution of their resources. In this regard, African systems, of all the different bird-pollination systems worldwide, have been least studied. I investigated the relationships between these aspects at population, community and landscape levels in the bird-pollination systems of the Cape Floristic Region. This biodiversity hotspot in the southwest of South Africa contains an unusually high number of bird-pollinated plant species relative to the number of pollinating bird species. Chapter 2 describes how I experimentally tested which nectar resource traits affect sunbird foraging behaviour at the small scale within populations. Sunbirds’ behaviour was largely determined by visual signals and distances between nectar resources. The birds showed flower colour preferences, but no flower constancy (selective foraging only on one flower type).

    11TH FLORA MALESINA SYMPOSIUM, BRUNEI DARUSSALM, 30 JUNE 5 JULY 2019 1 Welcome message The Universiti Brunei Darussalam is honoured to host the 11th International Flora Malesiana Symposium. On behalf of the organizing committee it is my pleasure to welcome you to Brunei Darussalam. The Flora Malesiana Symposium is a fantastic opportunity to engage in discussion and sharing information and experience in the field of taxonomy, ecology and conservation. This is the first time that a Flora Malesiana Symposium is organized in Brunei Darissalam and in the entire island of Borneo. At the center of the Malesian archipelago the island of Borneo magnifies the megadiversity of this region with its richness in plant and animal species. Moreover, the symposium will be an opportunity to inspire and engage the young generation of taxonomists, ecologists and conservationists who are attending it. They will be able to interact with senior researchers and get inspired with new ideas and develop further collaboration. In a phase of Biodiversity crisis, it is pivotal the understanding of plant diversity their ecology in order to have a tangible and successful result in the conservation action. I would like to thank the Vice Chancellor of UBD for supporting the symposium. In the last 6 months the organizing committee has worked very hard for making the symposium possible, to them goes my special thanks. I would like to extend my thanks to all the delegates and the keynote speakers who will make this event a memorable symposium.
