IV. on the Proteaceć of Jussieu. by Mr. Robert Brown, Lib. LS
IV. On the Proteacea of Jussieu. By -Mr. Robert Brown, Lib. L.S. Read Jan. 17, 1809. THELinnean system of botany, though confessedly artificial, has not only contributed more than all others to facilitate tlie knowledge of species, but, by constantly directing the attention to those essential parts of the flower on which it is founded, has made us acquainted with more of their important modific-a t’ ions than we probably should have known, had it not been generally adopted, and has thus laid a more solid foundation for the esta- blishment of a natural arrangement, the superior importance of which no one has been inore fully impressed with than Linnzus hiinself. There are still, however, certain circumstances respccting the stamina and pistilla, which appear to iiie to havc been much less attended to than they deserve, both by Linneus and succeeding botanists. What I chiefly allude to is the state of these organs before the expansion of the flower. Tlie utility of ascertaining the internal condition of the ovarium before fecundation will liardly be called in question, now that the immortal worlis of Gxrtner and Jussieu hare demonstrated the necessity of minutely studying the fruits of plants in attempting to arrange tlicin ac- cording to tlic sum of their affinities, as in many cases the true nature of tlie ripc fruit, cspecially witli respect to the placenta- tion of the seeds, can oiily be detcrniined by this mc;~ns. Its importance is indeed expressly inculcated by many l~ot:inists, Tf’llO, 16 Mr. BROWN,on the Proteacee of Jussieu. -

Anatomical Adaptations in the Leaves of Selected Fynbos Species
S.Afr.J.Bot., 1994, 60(2): 99 - 107 99 Anatomical adaptations in the leaves of selected fynbos species Al ison M. van der Merwe (nee Summerfield),· J.J.A. van der Walt and Elizabeth M. Marais Department of Botany, University of Stellenbosch, Stellenbosch, 7600 Republic of South Africa Received 23 August 1993; revised 6 December 1993 Fynbos plants experience very harsh conditions during the hot and dry summer months and their leaves are adapt ed to reduce the loss of water due to transpiration. The leaves of 46 selected fynbos species of 24 families were examined to determine which anatomical adaptations contribute to the reduced rate of transpiration and subse quent reduced water loss. Without exception, all species examined show leaf adaptations typical of xerophytic species. Four typical leaf types are recognized and proposed as models of leaf adaptation: 1. Myrsine type - dorsi ventral or isobilateral leaves; more palisade parenchyma present than spongy parenchyma; tissues contain large amounts of phenolic substances. 2. Meta/asia type - small dorsiventral leaves with involute margins and a single groove in the adaxial surface; mesophyll is usually inverted. 3. Retzia type - dorsi ventral or isobilateral leaves with revolute margins and one or two grooves in the abaxial surface; spongy parenchyma is the main component of the mesophyll. 4. Spatalla type - small centric or near-centric leaves; little or no spongy parenchy ma tissue. Fynbos plante ondervind uiterste toestande tydens die warm, droa somermaande, en hulle blare is aangepas om waterverlies tydens transpirasie te beperk. Blare van geselekteerde fynbos-spesies uit 24 families is ondersoek am die bydrae van die verskillende anatomiese aanpassings tot verminderde transpirasietempo en gevolglike water verlies, vas te stel. -
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). -

HURTLING TOWARDS EXTINCTION Five Charismatic, Threatened Red Data List Plants
HURTLING TOWARDS EXTINCTION Five charismatic, threatened Red Data List plants. byJanice Golding, SABONET, c/o National Botanical Institute, Pretoria Plant Red Data Lists list extinct, threatened and potentially threatened plants that have been assigned risk categories according to guidelines set by the World Conservation Union (IUCN). Approximately 10% of South Africa's plant species appear on the Red Data List (RDL). Preliminary expectations are that many species categorized as 'indeter minate' or 'uncertain' should in fact be removed from the forthcoming Red Data List. In this article, five plant species with RDL status are selected, all of which are found in habitats that are subjected to human modification. These charismatic plants can serve as important flagships for conserving ecologically sensitive habitats. No reference is made to grasslands and important plant groups (such as cycads or ground succulents) that also desperately require protection against extinction. APONOGETON RANUNCULIFLORUS Aponogeton ranunculiflorus (Aponogetonaceae) is an aquatic vascular plant, known from humic tarns (sandstone depressions filled with water) from the Drakensberg summit. The species grows at an altitude of 2 600 m in the mist belt. The species straddles Lesotho and KwaZulu-Natal. Its RDL status was assessed by Hilton-Taylor as 'rare' and as 'vulnerable' by Scott-Shaw (based on past population declines, its limited distrib ution range and the few number of known localities). The type specimen was collected in Lesotho's Sehlabathebe National Park, in a 3 ha zone and was first described in 1972. Subsequent surveys have found more localities, all of which are within a 10 kIn radius of the type locality. -

Pollen Morphology of Proteaceae Native to Argentina: a New Dichotomus Key for Their Identification
Rev. Mus. Argentino Cienc. Nat., n.s. 19(1): 25-37, 2017 ISSN 1514-5158 (impresa) ISSN 1853-0400 (en línea) Pollen morphology of Proteaceae native to Argentina: a new dichotomus key for their identification Damián Andrés FERNÁNDEZ Sección Paleopalinología, Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Av. A. Gallardo 470, C1405DJR Buenos Aires, Argentina. E-mail: [email protected]. Abstract: A dichotomous key for the identification of eight proteaceous species, native to Argentina, based on pollen morphology is presented. These species are: Embothrium coccineum, Gevuina avellana, Lomatia den- tata, L. ferruginea, L. hirsuta, Orites myrtoidea, Roupala meisneri and R. montana. The pollen morphology was analyzed with both, light and electron scanning microscopes. The morphological characters selected for species/ genera recognition are: ornamentation, pore number, equatorial diameter, the ratio of sexine/nexine thickness, and equatorial diameter/pore diameter ratio. Key words: Proteaceae, Argentina, palynology, dichotomous key. Resumen: Morfología polínica de las Proteaceae nativas de Argentina: una nueva clave dicotómi- ca para su identificación.
