SMITH. AN INTRODUCTION TO THE FLORA OF NATAL AND ZULULAND BY J. W. BEWS, M.A. D.Sc. Professor of Botany in the Natal University College. a 4 LIFRARYT ; aW YORE 3 NM ; 1921: Printed and Published by €ITY PRINTING WORKS, Bank Street, PIETERMARITZBURG. PREFACE. The following work has been written for the purpose of assisting the study of plant ecology and botanical survey work in Natal. The “Handbook” published by the late Dr. Medley Wood is now no longer up to date, and is also out of print, and his “Revised List,” with its supplements, is also incomplete, as well as difficult to procure. A general ecological account of the Natal vegetation, to a large extent compiled from my own previous writings, has been prepared, and it was intended that it should be included as part of the present work, but for various reasons it has been thought advisable to defer publication of this part of the manuscript. This has enabled the main section to be published in a more compact form. Ecological notes have been added in the case of the principal species to the records of dis- tribution. Care has been taken to make the latter as complete and accurate as possible. Various Zulu names have also been included. The works enumerated in the Bibliography have been con- sulted throughout, and due acknowledgment of indebtedness - must be made in particular to Medley Wood's various lists, to the “Flora Capensis,” to Engler’s “Fflanzenfamilien,” and Thonner’s “Flowering Plants of Africa.” In the key to the families the last mentioned work was found particularly helpful, since, after due consideration, it was decided that the main principles of sub-division adopted by Thonner were more useful and easier -to follow than any that could be substituted, without departing altogether from the natural system. The main groups are decided by the characters of the perianth, and the sub-divisions by the characters of the ovary and ovules. In many cases where there is a likelihood of mistakes being made, the family is included under more than one division. The keys given in the Flora Capensis have also been drawn upon freely. Considerable simplication throughout has been rendered possible, chiefly by the fact that a smaller area is dealt with. An attempt has been made to bring the nomenclature as up to date as possible, though it is hardly possible to attempt anything approaching finality in this. respect until many further monographs have been published by specialists on various families and genera. As it is, the changes that have been found Vi. necessary on Medley Wood’s “Revised List,” as well as the additions, are considerable. The Flowering Plants of Natal, as now arranged, belong to 148 families, and include 901 genera and 3,786 species, as compared with 128 families, 865 genera, and 3,310 species as given by Medley Wood. My thanks are due to Mrs. Bolus for putting the Bolus Her- barium and Library at my disposal, and to Dr. R. Marloth for the use of his private library. J. W. BEWS. Natal University College, May, 1921. INTRODUCTION. The history of Botany in Natal extends over a period of less than a century, though many of the Natal plants were collected more than a hundred years ago in the Cape Colony by Thunberg, Burchell and others. The first Botanist of note to visit Natal was J. F. Drége, who, in the year 1832, travelled northwards together with Dr. Andrew Smith, along the Natal coast belt as far as the Umgeni north of Durban. Drége spent eight years altogether in botanical exploration in South Africa, and when he left he took with him, according to Meyer, about 200,000 dried specimens belonging to nearly 8,000 distinct species. About the time that Drége visited Natal, Ecklon and Zeyher were col- lecting in the Eastern parts of the Cape Colony, but they did not get further east than the Kei River. In 1839 Ferdinand Krauss visited Natal and collected chiefly on the coast belt. In his account of the flora of the Cape and Natal (1846) he divides Natal into the three botanical sub-divi- sions still recognised, viz., Coast belt, Midlands, and Mountains (Drakensberg). Other early Natal collectors were Dr. Gueinzius, Vance, Wil- liamson, R. W. Plant and EF. Armitage. During the twenty years following the colonisation of Natal by white settlers, botanical collecting made rapid strides, and when the first volume of Harvey and Sonder’s “Flora Capensis” was published in 1859, acknowledgment was made to John Sanderson, of Durban (after whom the genus Sandersonia is named), for valuable collections ; to Dr. Sutherland, Surveyor-General of Natal, for smal!, but carefully selected, collections made in various parts of his dis- trict during hasty professional visits, in one of which he dis- covered Greyia sutherlandi; to R. Hal'ack, of Port Elizabeth, for interesting information on plants of the Natal Colony, ac- companied by specimens. During the same period, Dr. Pappe, the Cape colonial botanist, was forwarding specimens, not all collected by himself, to Harvey, some of which, doubtless, may have come from Natal. In the second volume of the Flora Capensis, published in 1861—2, large collections are acknowledged from W. T. Gerrard and M. J. McKen, Curator of the Botanical Gardens at Durban, jointly and severally. The collections must have been sent sub- 2. _ INTRODUCTION. sequent to the publication of Volume I., since many of the new discoveries are dealt with in the addendum to the second volume, and in the second volume of Harvey’s “Thesaurus,” published in 1863. The publication of these ‘works seems to have stimulated botanical exploration and collecting, for in the preface to Vol. III. of the Flora Capensis (1864—5) it is stated that large collections continued to be received from Sanderson, Gerrard and McKen, “the last-named gentleman having con- tributed within two years over one thousand species of plants.” George Fannin, of the Dargle, also commenced contributing, his collections including the beautiful new Anemone (A. fanninii). T. Cooper also collected largely in Natal in 1861—2. By this time MacOwan had commenced his botanical teach- ing at the Cape, and through his pupils, as well as by his own direct labours, botany in South Africa was rapidly advanced. Dr. H. Bolus is another to whom South African Botany owes much. In 1873—5 F. Oates travelled from Maritzburg northwards through Ladysmith, Newcastle, and the Transvaal to Matabele- land. In an appendix to his published journal, the plants col- lected by him were dealt with by R. A. Rolfe. In the years 1875—7 A. Rehmann made a journey from the Cape via Kimberley, Bloemfontein, Harrismith and Maritzburg to Durban. He visited Medley Wood at Inanda. His collec- tions were partly worked up by Szyszylowicz. (1887—8). Before this the Rev. John Buchanan had become an enthusi- astic and extensive collector. He devoted special attention to the ferns. J. Medley Wood had also commenced his _ botanical career. His name will always be remembered as that of the chief pioneer botanist in Natal. He was born on December Ist, 1827, and died at the advanced age of 88 years on August 26, 1915. He spent over 60 years in Natal, and he was active up to the end of his long life. For many years he lived at Inanda, and it was there his early botanical collecting was done. He was closely associated at that time with Buchanan. In 1882 he suc- ceeded McKen as Curator of the Durban Botanical Gardens and Herbarium, and he remained at his post for 33 years. He pub- lished several successive lists of the flora, and in his “Natal Plants” 600 species were illustrated. In association with Maurice S. Evans, who also collected widely, or with his assistant, Miss Franks, or independently, Wood described numbers of new species. He forwarded to Kew and other European herbaria large numbers of new species to be worked up by specialists. He built up the excellent Durban Herbarium. He was assisted at INTRODUCTION. 5. various times by Miss Franks, Messrs. Haygarth and Wylie, the last mentioned succeeding him as curator of the Durban Botanical Gardens. Space does not permit of more than a very brief mention of he numerous other coilectors or writers on the Botany of Natal. urther details may be learned from the list of publications Which follows. Only workers in, or visitors to Natal, are men- tivned, but it should be borne in mind that the Botany of Natal s a great deal to workers overseas especially the staff of the Hebarium at Kew. he following list is, it is hoped, fairly complete, though collettors who have contributed only occasional specimens are TFourcade (who was employed by the Government to in- _ vestigae and report on the forests of Natal), Justus Thode (who sei and wrote on the vegetation of Natal. (See Biblio- graphy), R. Schlechter (who collected extensively and added ‘arge nuttbers of new species). O. Kuntze, A. Engler, R. Marloth, Mrs. Fannn, Mrs. Saunders, Miss Owen, Mrs. Hutton, Miss Arm- strong, Mis G. Edwards, Mrs. Bolus, Dr. E. Doidge, Mrs. Stain- olus, A. Bolus, G. Mann, F. Bachmann, A. Penther, H. G. Flajagan, W. Tyson, H. Junod, F. Wilms, H. Rudatis, Dr. Pole-Fyans, Dr. Dimock-Brown, Dr. van der Byl, Dr. Phillips, J. \. Henkel, A. O. D. Mogg, Dr. Schonland, Messrs. Krook, Stone Mariott, Aitken, Gale, Boyle, Allison, Large, Davis, St. George, \enkinson, Nelson, Baines, Reid, Eyles, Green, Mason, Krebs,Fernando, Symons, Groom, Pearse, Grant, Hewit- son, Carnegie. It may be wel to state that the above names are not arranged in any particular der, chronological or otherwise. Dr. T. R. Sim)formerly Conservator of Forests for Natal, has contributed in \s various published works a great amount of information regating the flora. of S. Africa in general, in- cluding that of Natah, He has made the trees and shrubs, the ferns and the mosses #d hepatics his special objects of study, but he has collected a the other plants as well. He has lately very generously pieseqnted his Herbarium of Flowering Plants to the Botany partment of the Natal University College. The writer of this wrk has since 1910 devoted most of his attention to the study ¢ the vegetation of Natal, chiefly from the ecological standpoint, { field that had hitherto remained un- touched so far as Natal ws concerned.
