Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi
YIKA-VWAZA TRUST RESEARCH STUDY REPORT N (2017/18) Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi By Sopani Sichinga ([email protected]) September , 2019 ABSTRACT In 2018 – 19, a survey on vascular plants was conducted in Vwaza Marsh Wildlife Reserve. The reserve is located in the north-western Malawi, covering an area of about 986 km2. Based on this survey, a total of 461 species from 76 families were recorded (i.e. 454 Angiosperms and 7 Pteridophyta). Of the total species recorded, 19 are exotics (of which 4 are reported to be invasive) while 1 species is considered threatened. The most dominant families were Fabaceae (80 species representing 17. 4%), Poaceae (53 species representing 11.5%), Rubiaceae (27 species representing 5.9 %), and Euphorbiaceae (24 species representing 5.2%). The annotated checklist includes scientific names, habit, habitat types and IUCN Red List status and is presented in section 5. i ACKNOLEDGEMENTS First and foremost, let me thank the Nyika–Vwaza Trust (UK) for funding this work. Without their financial support, this work would have not been materialized. The Department of National Parks and Wildlife (DNPW) Malawi through its Regional Office (N) is also thanked for the logistical support and accommodation throughout the entire study. Special thanks are due to my supervisor - Mr. George Zwide Nxumayo for his invaluable guidance. Mr. Thom McShane should also be thanked in a special way for sharing me some information, and sending me some documents about Vwaza which have contributed a lot to the success of this work. I extend my sincere thanks to the Vwaza Research Unit team for their assistance, especially during the field work. -

Creation and Carnivory in the Pitcher Plants of Nepenthaceae and Sarraceniaceae
OPEN ACCESS JCTS Article SERIES B Creation and Carnivory in the Pitcher Plants of Nepenthaceae and Sarraceniaceae R.W. Sanders and T.C. Wood Core Academy of Science, Dayton, TN Abstract The morphological adaptations of carnivorous plants and taxonomic distributions of those adaptations are reviewed, as are the conflicting classifications of the plants based on the adaptations, reproductive morphology, and DNA sequences. To begin developing a creationist understanding of the origin of plant carnivory, we here focus specifically on pitcher plants of Nepenthaceae and Sarraceniaceae because their popularity as cultivated curiosities has generated a literature resource amenable to baraminological analysis. Hybridization records were augmented by total nucleotide differences to assess species similarities. Nonhybridizing species falling within the molecular range of hybridizing species were included in the monobaramin of the hybridizing species. The combined data support each of the three genera of the Sarraceniaceae as a monobaramin, but the three could not be combined into a larger monobaramin. With the Nepenthaceae, the data unequivocally place 73% of the species in a single monobaramin, strongly suggesting the whole genus (and, thus, family) is a monobaramin. The lack of variation in the carnivorous habit provides no evidence for the intrabaraminic origin of carnivory from non-carnivorous plants. An array of fascinating symbiotic relationships of pitchers in some species with unusual bacteria, insects, and vertebrates are known and suggest the origin of carnivory from benign functions of the adaptive structures. However, these symbioses still do not account for the apparent complex design for carnivory characteristic of all species in the two families. Editor: J.W. -

CONTRIBUTIONS FROM THE United States National Herbarium Volume XII, Part 3 TXE&3 OF AMERICAN GRASSES . / A STUDY OF THE AMERICAN SPECIES OF GRASSES DESCRIBED BY LINNAEUS, GRONOVIUS, SLOANE, SWARTZ, AND MICHAUX By A. S. HITCHCOCK z rit erV ^-C?^ 1 " WASHINGTON GOVERNMENT PRINTING OFFICE 1908 BULLETIN OF THE UNITED STATES NATIONAL MUSEUM Issued June 18, 1908 ii PREFACE The accompanying paper, by Prof. A. S. Hitchcock, Systematic Agrostologist of the United States Department of Agriculture, u entitled Types of American grasses: a study of the American species of grasses described by Linnaeus, Gronovius, Sloane, Swartz, and Michaux," is an important contribution to our knowledge of American grasses. It is regarded as of fundamental importance in the critical sys- tematic investigation of any group of plants that the identity of the species described by earlier authors be determined with certainty. Often this identification can be made only by examining the type specimen, the original description being inconclusive. Under the American code of botanical nomenclature, which has been followed by the author of this paper, "the nomenclatorial t}rpe of a species or subspecies is the specimen to which the describer originally applied the name in publication." The procedure indicated by the American code, namely, to appeal to the type specimen when the original description is insufficient to identify the species, has been much misunderstood by European botanists. It has been taken to mean, in the case of the Linnsean herbarium, for example, that a specimen in that herbarium bearing the same name as a species described by Linnaeus in his Species Plantarum must be taken as the type of that species regardless of all other considerations. -
CATALOGUE of the GRASSES of CUBA by A. S. Hitchcock
CATALOGUE OF THE GRASSES OF CUBA By A. S. Hitchcock. INTRODUCTION. The following list of Cuban grasses is based primarily upon the collections at the Estaci6n Central Agron6mica de Cuba, situated at Santiago de las Vegas, a suburb of Habana. The herbarium includes the collections made by the members of the staff, particularly Mr. C. F. Baker, formerly head of the department of botany, and also the Sauvalle Herbarium deposited by the Habana Academy of Sciences, These specimens were examined by the writer during a short stay upon the island in the spring of 1906, and were later kindly loaned by the station authorities for a more critical study at Washington. The Sauvalle Herbarium contains a fairly complete set of the grasses col- lected by Charles Wright, the most important collection thus far obtained from Cuba. In addition to the collections at the Cuba Experiment Station, the National Herbarium furnished important material for study, including collections made by A. H. Curtiss, W. Palmer and J. H. Riley, A. Taylor (from the Isle of Pines), S. M. Tracy, Brother Leon (De la Salle College, Habana), and the writer. The earlier collections of Wright were sent to Grisebach for study. These were reported upon by Grisebach in his work entitled "Cata- logus Plant arum Cubensium," published in 1866, though preliminary reports appeared earlier in the two parts of Plantae Wrightianae. * During the spring of 1907 I had the opportunity of examining the grasses in the herbarium of Grisebach in Gottingen.6 In the present article I have, with few exceptions, accounted for the grasses listed by Grisebach in his catalogue of Cuban plants, and have appended a list of these with references to the pages in the body of this article upon which the species are considered. -

Eustachys Retusa (POACEAE) in SYSTEMS with INTENSIVE GLYPHOSATE APPLICATION1
Morpho-architectural traits that allow the regeneration of ... 709 MORPHO-ARCHITECTURAL TRAITS THAT ALLOW THE REGENERATION OF Eustachys retusa (POACEAE) IN SYSTEMS WITH INTENSIVE GLYPHOSATE APPLICATION1 Características Morfoarquiteturais que Possibilitam a Regeneração de Eustachys retusa (Poaceae) em Sistemas com Uso Intensivo de Glifosato PANIGO, E.S.2, ALESSO, C.A.2, DELLAFERRERA, I.M.2, OLIVELLA, J.2, and PERRETA, M.G.2 ABSTRACT - Eustachys retusa has low sensitivity to glyphosate at the reproductive stage. The purpose of this study was to analyze the effect of glyphosate on adult E. retusa plants in order to identify the traits that make possible their regeneration in no-tillage systems. For this purpose, reproductive-stage specimens from wild populations were treated with glyphosate at two different rates (480 and 1,200 g a.i. ha-1) including a non-treated control. Results demonstrated that glyphosate could control E. retusa plants at reproductive stage at 1,200 g a.i. ha-1 dose. However, a certain proportion of plants can survive despite having full chlorosis as a consequence of basal bud activation (bud bank) and the presence of reserves in the rhizome. These combinations of morphological traits facilitate the recovery of foliar mass in some plants after the application of the herbicide. This behavior represents a serious problem because E. retusa plants retain the ability to regrow. This shows that, E. retusa management at reproductive stage must be complemented with other cultural and/or chemical tactics. Keywords: argentine fingergrass, herbicide, weed, tolerance, morphological changes. RESUMO - Eustachys retusa é uma praga com baixa sensibilidade ao herbicida glifosato na etapa reprodutiva. -
Sabatia Stellaris Pursh Sea Pink
New England Plant Conservation Program Sabatia stellaris Pursh Sea pink Conservation and Research Plan for New England Prepared by Richard W. Enser Coordinator/Botanist, Rhode Island Natural Heritage Program Providence, Rhode Island For: New England Wild Flower Society 180 Hemenway Road Framingham, Massachusetts 01701 USA 508/877-7630 e-mail: [email protected] website: www.newfs.org Approved, Regional Advisory Council, May 2004 1 SUMMARY _____________________________________________________________ Sabatia stellaris Pursh, Sea Pink, is a member of the Gentian Family (Gentianaceae) that grows on open sandy soils at the upper edges of salt and brackish marshes and interdunal depressions. The plant is widely distributed in the states along the Atlantic and Gulf Coasts, and is considered to be abundant in the southern portion of its range. It is rare in New York and New England at the northeastern limits of its distribution. Sabatia stellaris is an annual that usually grows as one main stem with branching on the upper half. In the northern part of its range, plants grow to 20 cm. Flowers consist of a 4 to 7-lobed corolla that ranges from crimson-pink to light pink and sometimes white. The white-flowering form is widespread in the southern part of its range; however, this form constituted 75% of a Connecticut population in 2003, which is considered the first documentation of this form in New England. As an annual, S. stellaris exhibits extreme variability in the number of plants found at an occurrence in a given year. For example, in 2002 the estimated number of plants at three of the extant New England populations numbered about 1000, with an absence of plants from the fourth occurrence. -
Inselbergs) As Centers of Diversity for Desiccation-Tolerant Vascular Plants
Plant Ecology 151: 19–28, 2000. 19 © 2000 Kluwer Academic Publishers. Printed in the Netherlands. Dedicated to Prof. Dr Karl Eduard Linsenmair (Universität Würzburg) on the occasion of his 60th birthday. Granitic and gneissic outcrops (inselbergs) as centers of diversity for desiccation-tolerant vascular plants Stefan Porembski1 & Wilhelm Barthlott2 1Universität Rostock, Institut für Biodiversitätsforschung, Allgemeine und Spezielle Botanik, Rostock, Germany (E-mail: [email protected]); 2Botanisches Institut der Universität, Bonn, Germany (E-mail: [email protected]) Key words: Afrotrilepis, Borya, Desiccation tolerance, Granitic outcrops, Myrothamnus, Poikilohydry, Resurrection plants, Velloziaceae, Water stress Abstract Although desiccation tolerance is common in non-vascular plants, this adaptive trait is very rare in vascular plants. Desiccation-tolerant vascular plants occur particularly on rock outcrops in the tropics and to a lesser extent in temperate zones. They are found from sea level up to 2800 m. The diversity of desiccation-tolerant species as mea- sured by number of species is highest in East Africa, Madagascar and Brazil, where granitic and gneissic outcrops, or inselbergs, are their main habitat. Inselbergs frequently occur as isolated monoliths characterized by extreme environmental conditions (i.e., edaphic dryness, high degrees of insolation). On tropical inselbergs, desiccation- tolerant monocotyledons (i.e., Cyperaceae and Velloziaceae) dominate in mat-like communities which cover even steep slopes. Mat-forming desiccation-tolerant species may attain considerable age (hundreds of years) and size (several m in height, for pseudostemmed species). Both homoiochlorophyllous and poikilochlorophyllous species occur. In their natural habitats, both groups survive dry periods of several months and regain their photosynthetic activity within a few days after rainfall. -

The first case of glyphosate resistance in C. virgata was found in 2015 in Australia, and since then several cases have been confirmed in several biotypes across Australia. Pot studies were conducted with 10 biotypes of C. virgata to determine glyphosate resistance levels. The biotypes were identified as either susceptible, moderately resistant or highly resistant based on the glyphosate dose required to kill 50% of plants. Two glyphosate-susceptible (GS) and two glyphosate-resistant (GR) biotypes were identified by the dose-response study and analyzed for the presence of target-site mutation in the 5–enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene. Performance of alternative herbicides to glyphosate as well as the double-knock herbicide approach was evaluated on the two GS (Ch and SGM2) and two GR (SGW2 and CP2) biotypes. Three herbicides, clethodim, haloxyfop and paraquat, were found to be effective (100% control) against all four biotypes when applied at the 4–5 leaf stage. -
A Checklist of Lesotho Grasses
Guidelines for Using the Checklist The genera and species are arranged in alphabetical order. Accepted genus and species names are in bold print, for example, Agrostis barbuligera. Synonyms are in italics, for example, Agrostis natalensis. Not all synonyms for a species are listed. Naturalised taxa are preceded by an asterisk, for example, Pennisetum *clandestinum. These are species that were intro- duced from outside Lesotho but now occur in the wild as part of the natural flora. Single letters after the species names, on the right-hand side of the column, indicate the distribution of species within Lesotho as reflected by the ROML and MASE collections. This indicates that a species has definitely been recorded in Lesotho. L—Lowlands F—Foothills M—Mountains S—Senqu Valley Double letters after species names, on the right-hand side of the column, indicate the distribution of species along the border with South Africa as reflected in the literature. This indicates that a species could occur in Lesotho, but has not yet been recorded.
