C'atalo(;uk ok Vasculak Plants of Tuansvaal and Swaziland. 2'M 



staiiees, 1 have included the new records from those of ni}' own coUec- 

 tiun.s which iiave been Identified. Miss Leendertz has added the 

 localities from her collections, which include man\' new records, and 

 the Rev. F. A. Rogers has kindly furnished a list of his. Dr. Bolus 

 has most generously agreed to compare the final MSS. with the 

 specimens in his herbarium, and to add any additional records or 

 localities which he may find there. 



T wish to record here my warm appreciation of the invaluable 

 assistance which Dr. Bolus has rendered in the detejinination of 

 doubtful or critical species. This work has been rendered necessary 

 by our lack, in the Trans\aal, of adequate literature and of authenti- 

 cally named specimens for comparison. T am also greatly indebted to 

 the director and staff of the Royal Botanic Gardens, Kew, for the com- 

 parison of much critical material, and for determination and publica- 

 tion of a numl^er of new species. To Mr. Spencer le M. Moore my 

 thanks are due for naming a set of specimens from Swaziland. To 

 our Vice-President, Prof. Schonland, I am also indebted for valuable 

 assistance in the determination of the Aloes and Crassulacea?. 



Collectors. 



Of the earlier South African collectors, Bnrchell, Krauss, Dreae 

 anrl Eckloii are not known to have reached that portion of the country 

 later defined as the Ti-ans\aal. Burchell's route lay to the westward, 

 in southern Bechuanahuul. 



The first Transvaal collections of which I have any record were 

 made by Zeyher and Burke in the late twenties or early thirties ; thej^ 

 appear to have worked together, for though Zeyher was the botanist 

 and Burke was primarily interested in antelopes, the latter made a 

 botanical collection separate]}- numbered, which is deposited in the 

 Kew herbarium. They appear to have made their headquarters for 

 some months in or near Pretoria, a large number of theii- specimens, 

 collected through a series of months, being labelled as from the Aapjes 

 River. They als(j collected along the Magaliesberg at the Crocodile 

 and Hex rivers, and at the " Mooi River," presumably at the old 

 capital, Potchefstroom. I cannot find that they collected north of the 

 Magaliesberg. 



After the \isit of Burke and Zeyhei- a long period inter\ened 

 during which no Transvaal collections appear to have been made. 

 With the opening of the Mac-a-Mac gold-fields, near Pilgrim's Rest, 

 a few men of scientific bent found their way th.ere. Among the.se 

 were McLea, Mudd and Dr. Athei-stone (1871 and 1873), all of whom 

 collected plants, not only at Mac-a-Mac, but also at Pretoria, en route : 

 but their collections were not extensive. 



Next to those of Burke and Zeyher, the most important contribu- 

 tions to our knowledge c>f the Transvaal flora were made by Mr. E. E. 

 Galpin, Dr. A. Rehmann, Dr. F. Wilms and Dr. R. Schlechter.
