l^A SCIENCE IN AFRICA 



was carried out by H. Bolus, Schonland, Marloth, and Medley 

 Wood. The work published under the direction of Dr. I. B. Pole 

 Evans from the Division of Plant Industry at Pretoria is very exten- 

 sive some of the most important contributions being those of E. P. 

 Philhps, I. C. Verdoorn, R. A. Dyer, and H. G. W. J. Schweic- 

 kerdt. In addition to these government workers, much investiga- 

 tion has been carried out by other Transvaal botanists, specially 

 by C. E. Moss and Mrs. Moss (University of Witwatersrand), 

 Miss A. A. Obermeyer and C. E. B. Bremekamp, whose paper on 

 the origin of the flora of the Kalahari is of particular note. Sys- 

 tematic research in the Cape Province is centred at the Bolus 

 Herbarium, whence many important papers have been published, 

 notably by Mrs. L. Bolus (present Curator) and N. S. Pillans. 

 Valuable work has also been carried out at the Stellenbosch 

 University, especially by P. A. van der Bijl and Miss A. V. 

 Duthie. From the University of Capetown R. S. Adamson has 

 published important treatises {see under Ecology) and Mrs. Levyns 

 several important systematic papers, including a useful handbook 

 on the Flora of the Cape Peninsula (1929b). The publication of a 

 new Flora of the Cape Peninsula has been commenced under the 

 general direction of Professor R. H. Compton. For Natal and 

 Zululand J. S. Henkel has published a book on woody plants 

 (1934)5 ^^^ ^^^ ^^^ whole of the Transvaal Dr. Burtt Davy (of the 

 Imperial Forestry Institute) is preparing a Flora embracing the 

 flowering plants and ferns, of which two parts (1926 and 1932) 

 have been published. Numerous other works of high value on 

 plant systematics have resulted from the Botanical Survey of the 

 Union of South Africa. Poisonous plants have been dealt with by 

 E. P. Phillips (1926) and later by Watt and Breyer-Brandwijk in 

 their important volume entitled 77?^ Medicinal and Poisonous Plants of 

 South Africa (1932). In the field of biochemical and physiological 

 research Dr. Marguerite Henrici has made valuable contributions 

 on various problems connected with the study of South African 

 grasses and other pasture plants. Further details need not be given 

 here since Dr. E. P. Phillips (1930) has provided an historical 

 sketch of the whole development of botanical science in South 

 Africa.
