Haemanthus Canaliculatus | Plantz Africa About:Reader?Url=
Haemanthus canaliculatus | Plantz Africa about:reader?url=http://pza.sanbi.org/haemanthus-canaliculatus pza.sanbi.org Haemanthus canaliculatus | Plantz Africa Introduction In late summer or early autumn, after fires have swept through some of the swampy areas near the sea in the Hangklip area, you may be lucky enough to see the red paintbrushes of Haemanthus canaliculatus glowing brightly amongst the blackened remains of the vegetation. Description Description The bulbs are made up of a number of thick, fleshy, cream-coloured, overlapping, truncated bulb scales, arranged like a fan, with perennial fleshy roots. There are usually 2 (sometimes 1, 3 or 4) narrow smooth fleshy leaves up to 600 mm long, curved along 1 of 5 2016/12/14 03:51 PM Haemanthus canaliculatus | Plantz Africa about:reader?url=http://pza.sanbi.org/haemanthus-canaliculatus their length to form a channel. They are 5-27 mm wide, shiny green with reddish barred markings towards the base, especially on the lower surface. The smooth, thick, flattened, upright or curved flower stalks can be up to 200 mm long, 4-10 mm wide and are reddishpink to deep red, sometimes with deeper red spots especially near the base; 5-7 pointed, leathery bracts, called spathes, surround the 15-45 flowers clustered at the top of the stalk. The spathes and flowers are usually red but very occasionally may be pink. The flowers are topped with yellow anthers. The reddish berries are round and about 20 mm in diameter. Under natural conditions the flowering time is from February to March and the leaves usually appear after the flowers from May to December. -

Newsletter No. 4 Autumn 2005
The Southern African Bulb Group Newsletter No. 4 Autumn 2005 The Southern African Bulb Group was initiated by a group of enthusiasts on April 4th 2004. The objective of the group is to further the understanding of the cultivation of Southern African bulbs, where `bulbs' is used in the broad sense to encompass bulb-, corm- and tuber- possessing Southern African plants, including `dicots' such as Oxalis. In the first instance the group will be run on an informal basis, with an initial subscription of £5 invited from participants. Committee: Robin Attrill (Membership secretary and Newsletter editor), Margaret Corina (Treasurer), Stefan Rau and Terry Smale Editorial This issue of the newsletter contains a report of the meeting of the group held at Rupert Bowlby's Nursery on April 9th 2005, an article on Crinum moorei by David Corina, information on recent literature of interest to growers of Southern African bulbs, and an updated list of suppliers of seed and bulbs/corms of Southern African geophytes. In addition a balance sheet covering the first year of operation of the group is attached. With respect to the supplier list, please let me know if you are aware of other sources which should be included. As I have previously stated the group welcomes articles, and suggestions, for inclusion in future newsletters. Contributions (hand/typewritten and electronic are acceptable!) are urgently required and should be sent to the newsletter editor at 17 Waterhouse Moor, Harlow, Essex, CM18 6BA (Email [email protected] ) Publication of the next issue is scheduled for December 2005. Report on visit to Rupert Bowlby - Saturday 9 th April 2005 by David Corina About 20 members attended the event, and the Group would like to thank Rupert for his hospitality at the event and for opening his collection to the public gaze. -

Fireball lilies of Africa: a molecular phylogeny of the genus Scadoxus Raf. (Amaryllidaceae) Kine Hals Bødker Master of Science Thesis Natural History Museum, University of Oslo Centre for Ecological and Evolutionary Synthesis, Department of Biosciences, University of Oslo June 15th 2020 © Kine Hals Bødker 2020 Fireball lilies of Africa: a molecular phylogeny of the genus Scadoxus Raf. (Amaryllidaceae) Kine Hals Bødker http://www.duo.uio.no/ Print: Reprosentralen, University of Oslo II Illustration: Aasne Aarhus, 1976. III IV Acknowledgements It has been an exciting journey working with the most beautiful plant genus of this world. There are many people I would like to thank for being a part of this journey. First and foremost, I want to thank my wonderful supervisors for all their help and support over the past two years. I could not have had a better team. My main supervisor, Charlotte - for your enthusiasm, knowledge, support and the most amazing field trips. In the 1970’s, before I was even born, Inger (and colleagues) worked with Scadoxus, which set the stage for this master thesis. I would like to thank Inger for being my additional supervisor and ultimately giving me this opportunity, and helping me understand more of Scadoxus morphology. Anne – for helping with the analyses, and especially for the incredibly helpful checking of spelling, grammatical errors and also helping me discourse my occasionally overwhelming results. Prof. Clemence Zimudzi and Dr. Tesfaye Awas – for fantastic field work experiences in Zimbabwe and Ethiopia, respectively. I would also like to thank the little kids in Ethiopia who helped us find Scadoxus specimens in places we never would have found without them. -

E-mail [email protected] Received: 17 July 2015 Returned for revision: 1 September 2015 Accepted: 23 December 2015 Published electronically: 24 March 2016 Background and Aims Obdiplostemony has long been a controversial condition as it diverges from diploste- mony found among most core eudicot orders by the more external insertion of the alternisepalous stamens. In this paper we review the definition and occurrence of obdiplostemony, and analyse how the condition has impacted on floral diversification and species evolution. Key Results Obdiplostemony represents an amalgamation of at least five different floral developmental pathways, all of them leading to the external positioning of the alternisepalous stamen whorl within a two-whorled androe- cium. In secondary obdiplostemony the antesepalous stamens arise before the alternisepalous stamens. The position of alternisepalous stamens at maturity is more external due to subtle shifts of stamens linked to a weakening of the alternisepalous sector including stamen and petal (type I), alternisepalous stamens arising de facto externally of antesepalous stamens (type II) or alternisepalous stamens shifting outside due to the sterilization of antesepalous sta- mens (type III: Sapotaceae). -

The eradication and control of invasive alien plants (IAP) is essential for the restoration of native plant communities. Understanding ecological impacts and potential invasive risks of IAP is important for their effective management, particularly for prioritisation. Most studies concerning impacts on vegetation structure and plant-pollinator interactions have measured few ecological metrics, resulting in a superficial understanding of plant species invasion. -

<I>Phytophthora</I> Taxa Associated with Cultivated <I>Agathosma</I
Persoonia 25, 2010: 32– 49 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158510X538371 Phytophthora taxa associated with cultivated Agathosma, with emphasis on the P. citricola complex and P. capensis sp. nov. C.M. Bezuidenhout1, S. Denman 2, S.A. Kirk 2, W.J. Botha3, L. Mostert 4, A. McLeod4 Key words Abstract Agathosma species, which are indigenous to South Africa, are also cultivated for commercial use. Re- cently growers experienced severe plant loss, and symptoms shown by affected plants suggested that a soilborne avocado disease could be the cause of death. A number of Phytophthora taxa were isolated from diseased plants, and this buchu paper reports their identity, mating type, and pathogenicity to young Agathosma plants. Using morphological and fynbos sequence data seven Phytophthora taxa were identified: the A1 mating type of P. cinnamomi var. cinnamomi, P. cin- glucose-6-phosphate isomerase namomi var. parvispora and P. cryptogea, the A2 mating type of P. drechsleri and P. nicotianae, and two homothallic isozymes taxa from the P. citricola complex. The identity of isolates in the P. citricola complex was resolved using reference malate dehydrogenase isolates of P. citricola CIT groups 1 to 5 sensu Oudemans et al. (1994) along with multi-locus phylogenies (three pathogenicity nuclear and two mitochondrial regions), isozyme analyses, morphological characteristics and temperature-growth root-rot studies. These analyses revealed the isolates from Agathosma to include P. multivora and a putative novel species, taxonomy P. taxon emzansi. Furthermore, among the P. citricola reference isolates the presence of a new species was revealed, described here as P. capensis. -
Kirstenbosch NBG List of Plants That Provide Food for Honey Bees
Indigenous South African Plants that Provide Food for Honey Bees Honey bees feed on nectar (carbohydrates) and pollen (protein) from a wide variety of flowering plants. While the honey bee forages for nectar and pollen, it transfers pollen from one flower to another, providing the service of pollination, which allows the plant to reproduce. However, bees don’t pollinate all flowers that they visit. This list is based on observations of bees visiting flowers in Kirstenbosch National Botanical Garden, and on a variety of references, in particular the following: Plant of the Week articles on www.PlantZAfrica.com Johannsmeier, M.F. 2005. Beeplants of the South-Western Cape, Nectar and pollen sources of honeybees (revised and expanded). Plant Protection Research Institute Handbook No. 17. Agricultural Research Council, Plant Protection Research Institute, Pretoria, South Africa This list is primarily Western Cape, but does have application elsewhere. When planting, check with a local nursery for subspecies or varieties that occur locally to prevent inappropriate hybridisations with natural veld species in your vicinity.
