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. -
Grass Genera in Townsville
Grass Genera in Townsville Nanette B. Hooker Photographs by Chris Gardiner SCHOOL OF MARINE and TROPICAL BIOLOGY JAMES COOK UNIVERSITY TOWNSVILLE QUEENSLAND James Cook University 2012 GRASSES OF THE TOWNSVILLE AREA Welcome to the grasses of the Townsville area. The genera covered in this treatment are those found in the lowland areas around Townsville as far north as Bluewater, south to Alligator Creek and west to the base of Hervey’s Range. Most of these genera will also be found in neighbouring areas although some genera not included may occur in specific habitats. The aim of this book is to provide a description of the grass genera as well as a list of species. The grasses belong to a very widespread and large family called the Poaceae. The original family name Gramineae is used in some publications, in Australia the preferred family name is Poaceae. It is one of the largest flowering plant families of the world, comprising more than 700 genera, and more than 10,000 species. In Australia there are over 1300 species including non-native grasses. In the Townsville area there are more than 220 grass species. The grasses have highly modified flowers arranged in a variety of ways. Because they are highly modified and specialized, there are also many new terms used to describe the various features. Hence there is a lot of terminology that chiefly applies to grasses, but some terms are used also in the sedge family. The basic unit of the grass inflorescence (The flowering part) is the spikelet. The spikelet consists of 1-2 basal glumes (bracts at the base) that subtend 1-many florets or flowers. -

A BIBLIOGRAPHIC STUDY OF BEAUVOIS' AGROSTO- • GRAPHIE By Cornelia D. Niles WITH INTRODUCTION AND BOTANICAL NOTES By Aones Chase nrntODTJCTiON The Essai d?une Nouvelle Agrostographie ; ou Nouveaux Genres des Graminees; avec figures representant les Oaracteres de tous les Genres, by A. M. F. J. Palisot de Beauvois, published in 1812, is, from the standpoint of the nomenclature of grasses, a very important work, its importance being due principally to its innumerable errors, less so because of its scientific value. In this small volume 69 new genera are proposed and some 640 new species, new binomials, and new names are published. Of the 69 genera proposed 31 are to-day recognized as valid, and of the 640 names about 61 are commonly accepted. There is probably not a grass flora of any considerable region anywhere in the world that does not contain some of Beauvois' names. Many of the new names are made in such haphazard fashion that they are incorrectly listed in the Index Kewensis. There are, besides, a number of misspelled names that have found their way into botanical literature. The inaccuracies are so numerous and the cita- tions so incomplete that only a trained bibliographer* could solve the many puzzles presented. Cornelia D. Niles in connection with her work on the bibliography of grasses, maintained in the form of a card catalogue in the Grass Herbarium, worked out the basis in literature of each of these new names. The botanical problems involved, the interpretation of descriptions and figures, were worked out by Agnes Chase, who is also respon- sible for the translation and summaries from the Advertisement, Introduction, and Principles. -

BLUMEA 45 (2000) 443-475 Revision of Hemarthria (Gramineae- Andropogoneae-Rottboelliinae) E. van den Heuvel & J.F. Veldkamp Summary A taxonomic revision is given of Hemarthria R.Br. (Gramineae-Andropogoneae-Rottboelliinae) occurring in the warm to tropical areas of the Old World (mainly in SE Asia), with oneintroduced in the New. Fourteen and from Vietnam taxa are recognised, including a variety a new species pro- posed here. A neotype for the lectotype species had to be designated. Key words: Hemarthria, Gramineae, Rottboelliinae.
