PROTEACEAE – It's All About Pollination
PROTEACEAE – it’s all about pollination …….Gail Slykhuis Illustration Philippa Hesterman, images Ellinor Campbell & Marg McDonald A predominantly southern hemisphere plant family, Proteaceae is well represented in Australia, particularly in the West, but we do have our own equally special local representatives, some of which are outlined below. A characteristic feature of many genera within this plant family is the ‘pollen presenter’, which is a fascinating mechanism by which the pollen, which would otherwise be difficult to access for potential pollination vectors such as bees, birds and nectarivorous mammals, is positioned on the extended style of the flower, facilitating cross- pollination. The stigma, which is part of the style, is not mature at this time, thus avoiding self-pollination. A hand lens would enable you to clearly see pollen presenters on the following local representatives: Banksia marginata, Grevillea infecunda, Hakea spp., Isopogon ceratophyllus and Lomatia illicifolia. It is interesting to note that both Victorian Smoke-bush Conospermum mitchellii and Prickly Geebung Persoonia juniperina, also found in our district, do not have pollen presenters. Silver Banksia Banksia marginata This shrub or small tree is readily recognisable when flowering (Feb – July) by the conspicuous yellow pollen presenters, which are an obvious floral part of the banksia flower. These flowers then slowly mature into our iconic woody banksia cones. It is interesting to observe the changes in the nature of the pollen presenters as the flower develops. The white undersides of the leathery leaves provide a clue to the choice of common name with their tip being characteristically blunt or truncate. Anglesea Grevillea Grevillea infecunda One of our endemic plants, the Anglesea Grevillea was first named in 1986 and is Anglesea Grevillea found in several locations north west of Anglesea. -
Persoonia Levis Broad-Leaved Geebung
Persoonia levis Broad-leaved Geebung Geebung is an unusual name derived from Aboriginal languages: geebung is the name used by the Dharuk in the Sydney Region, and Jibbong by the Wiradjuri1. The genus name Persoonia, to our ears, is also unusual until you find out that it is named after a Dutch mycologist (someone who studies fungi), Christiaan Hendrik Persoon. Geebungs are endemic to Australia and there are almost 100 species which, for the most part, are found in eastern Australia, and in the SW corner of Western Australia. They are mostly small trees or shrubs. This particular species, Persoonia levis, common in Sydney bushland, grows along the central and north coast of NSW, and in the SE corner of NSW and NE corner of Victoria. We are accustomed to the subtle olives, blues, greys and yellowish greens of the foliage of the Australian bush but the Broad-leaved Geebung is quite a contrast with bright, apple green foliage. The fruits, too, are unusual, round and succulent, bright green colouring to purple, very different from the dry, hard fruits of other genera in the same (Proteaceae) family, for example, Needle Bush (Hakea), Telopea (Waratah), Grevillea and Woodly Pear (Xylomelum). Geebungs are also unusual in that they have seven chromosomes that are much larger than those of other Proteaceae2. Broad-leaved Geebung has papery bark that provides some protection from bushfires. Peel back the superficial burnt bark and you will find glorious, rich crimson beneath the blackened exterior. This species also has the potential to resprout after fires, and regenerate from seed. -

SIGNATURE: DATE: Stellenbosch University https://scholar.sun.ac.za PATHOGENS ASSOCIATED WITH DISEASES OF PROTEA, LEUCOSPERMUM ANDLEUCADENDRONSPP. SUMMARY The manuscript consists of six chapters that represent research on different diseases and records of new diseases of the Proteaceae world-wide. The fungal descriptions presented in this thesis are not effectively published, and will thus be formally published elsewhere in scientific journals. Chapter one is a review that gives a detailed description of the major fungal pathogens of the genera Protea, Leucospermum and Leucadendron, as reported up to 1996. The pathogens are grouped according to the diseases they cause on roots, leaves, stems and flowers, as well as the canker causing fungi. In chapter two, several new fungi occurring on leaves of Pro tea, Leucospermum, Telopea and Brabejum collected from South Africa, Australia or New Zealand are described. The following fungi are described: Cladophialophora proteae, Coniolhyrium nitidae, Coniothyrium proteae, Coniolhyrium leucospermi,Harknessia leucospermi, Septoria prolearum and Mycosphaerella telopeae spp. nov. Furthermore, two Phylloslicla spp., telopeae and owaniana are also redecribed. The taxonomy of the Eisinoe spp. -
Blushing Bride FAMILY NAME: Proteaceae Species and Cultivars Of
Plant Profile Botanical Name: Serruria florida Common Name: Blushing Bride FAMILY NAME: Proteaceae Species and cultivars of special interest: Serruria florida hybrids and cvv. such as ‘Sugar ’n’ Spice’, ‘Pretty in Pink’, ‘Super Blush’, ‘Carmen’ Origin: South Africa Availability: May to October Foliage Characteristics: Stem length is 30- 60 cm. They have papery white bracts or floral leaves surrounding the flower. The sugar and spice variety has pink on the white bracts too. 5- 10 stems per bunch. Floral Characteristics: Blushing bride have feathery tufts of white to pinkish flowers. Sugar and spice variety has pink flowers. Special features and characteristics of special interest: It is thought that blushing bride got its name because of its traditional use in Africa as bridal bouquets. The species was near extinction due to being over exploited until conservation measures in the 1960s and 70s kicked in. Botanical name given in honour of James Serrurier, an 18th century professor of Botany at the Unisversity of Utrecht. Maintenance, Cultural requirements and Post Harvest Treatments: Blushing Bride is grown on large bushes in plantations across Australia. They are also grown in South Africa, Israel and the US. Handle blushing brides gently as flowers dry out quickly. They can have floral preservative. It is unknown whether it is Ethylene sensitive. When stored in cool storage keep at at 2- 4 degrees. Strip leaves from water level down. Pest and Diseases: The pedicels are vulnerable to Botrytis infection, which causes them to collapse. They do not suffer from leaf blackening like protea species do but the leaves may turn black if submerged in buckets of solution or if held for too long. -

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). -
Endogenous Gibberellin Levels During Early Fruit Development of Macadamia
African Journal of Agricultural Research Vol. 6(20), pp. 4785-4788, 26 September, 2011 Available online at http://www.academicjournals.org/AJAR DOI: 10.5897/AJAR11.902 ISSN 1991-637X ©2011 Academic Journals Full Length Research Paper Endogenous gibberellin levels during early fruit development of macadamia Stephen J. Trueman Faculty of Science, Health and Education, University of the Sunshine Coast, Maroochydore DC 4558, Australia. E-mail: [email protected]. Tel: +61 7 54565033. Accepted 12 August, 2011 Gibberellins play a key role in flower and fruit development, and fruits often contain high gibberellin concentrations. This study quantified endogenous gibberellins in flowers and immature fruits of the macadamia cultivars, H2 and 246, to assist in developing growth-regulator treatments for improving fruit set. GA 1, GA 3, GA 8, GA 9 and GA 20 was detected in flowers or fruits of both cultivars, and GA 4 were detected in flowers of cultivar 246. The timing of gibberellin accumulation was consistent between cultivars but total concentrations were very low (< 7 pmol g -1 fresh weight). Low gibberellin levels are consistent with the inability of the gibberellin-synthesis inhibitor, paclobutrazol, to influence fruit retention in macadamia. Key words: Abscission, fruit drop, kernel, nut, paclobutrazol, plant growth regulators, Proteaceae. INTRODUCTION Macadamia ( Macadamia integrifolia , Macadamia development (Wilkie et al., 2008; de Jong et al., 2009), tetraphylla and hybrids) is a subtropical evergreen tree and fruits often contain high levels of endogenous that is grown in plantations in South Africa, Australia, gibberellins (Zhang et al., 2007; Ayele et al., 2010).

The work described in this thesis was carried out by me, except where otherwise acknowledged, and has not been submitted to any other university or institution. 3 “Yes, Duckie, you’re lucky you’re not Herbie Hart who has taken his Throm-dim-bu-lator apart” (Dr. Seuss 1973) 4 Abstract An understanding of rarity can provide important insights into evolutionary processes, as well as valuable information for the conservation management of rare and threatened species. In this research, my main objective was to gain an understanding of the biology of rarity by investigating colonization and extinction processes from an ecological and evolutionary perspective. I have focused on the genus Persoonia (family Proteaceae), because these plants are prominent components of the Australian flora and the distributional patterns of species vary dramatically, including several that are listed as threatened. -
Species of Botryosphaeriaceae Occurring on Proteaceae
Persoonia 21, 2008: 111–118 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158508X372387 Species of Botryosphaeriaceae occurring on Proteaceae S. Marincowitz1, J.Z. Groenewald 2, M.J. Wingfield1, P.W. Crous1,2 Key words Abstract The Botryosphaeriaceae includes several species that are serious canker and leaf pathogens of Pro- teaceae. In the present study, sequence data for the ITS nrDNA region were used in conjunction with morphological Botryosphaeria observations to resolve the taxonomy of species of Botryosphaeriaceae associated with Proteaceae. Neofusicoccum Fusicoccum luteum was confirmed from Buckinghamia and Banksia in Australia, and on Protea cynaroides in South Africa. Neofusicoccum A major pathogen of Banksia coccinea in Australia was shown to be N. australe and not N. luteum as previously Saccharata reported. Neofusicoccum protearum was previously reported on Proteaceae from Australia, Madeira, Portugal and South Africa, and is shown here to also occur in Hawaii and Tenerife (Canary Islands). Furthermore, several previous records of N. ribis on Proteaceae were shown to be N. parvum. Saccharata capensis is described as a new species that is morphologically similar to S. proteae. There is no information currently available regarding its potential importance as plant pathogen and pathogenicity tests should be conducted with it in the future.
