242 THE JOURNAL OF BOTANY 



The first fruit of this attachment was the Orchids of the Cape 

 Peninsula, containing thirty-six plates, pubHshed in 1888. Then 

 followed the first volume of the Icones Orchidearum Austro-Afri- 

 canorum, in two parts, published in 1893 and 1896, and the 

 second volume of the same work, published in 1911, the whole 

 comprising two hundred plates and descriptions made from living 

 plants sent from all parts of South Africa. His monograph of the 

 genus Erica for the Flora Capensis, in which he was assisted by 

 Professor Guthrie, was finished in 1903. This was followed by a 

 List of the Floioering Plants and Ferns of the Cape Peninsula, in 

 conjunction with Major Wolley-Dod. He devoted a great deal of 

 time to the study of the geographical distribution of plants in 

 South Africa, and published two sketches on the subject — one in 

 1886, together with a map of the botanical regions, and the other 

 in 1905 for " Science in South Africa," commemorating the visit 

 of the British Association. It was in this connection that he 

 translated the Zivei Pflanzengeographische Documente of Ernst 

 Meyer. In collaboration with Dr. MacOwan he prepared, under the 

 name of the Herbarium Normale Austro-Africanum, a large number 

 of sets for distribution to all the principal European herbaria. 



His more important botanical journeys in South Africa in- 

 cluded all the coast regions to Nama'land Minor on the west and 

 Delagoa Bay on the east, various parts of the Transvaal as far 

 north as the Houtbosch, Swazieland, Orange Free State with the 

 slopes of the Drakensbergen, and most of the rich botanical areas 

 in the Cape Colony. 



In the year 1873 Bolus became a Fellow of the Linnean Society, 

 and he was one of the original members of the South African 

 Philosophical Society, now the Eoyal Society of South Africa. 

 Eight years ago the University of the Cape of Good Hope con- 

 ferred upon him the honorary degree of Doctor of Science, and in 

 1909 he was awarded the bronze medal and a grant of £50— a 

 graceful tribute instituted by the members of the British Associa- 

 tion in commemoration of their visit to South Africa, and annually 

 presented to the chosen scientific men of that country. He made 

 frequent visits to England, working up his plants, at Kew, and 

 consulting the National Herbarium. He also travelled in France, 

 Switzerland, Italy, and Greece, and the numerous pencil and 

 water-colour sketches he has made bear testimony to the eager 

 enjoyment he derived from his journeyings. 



During all this time Bolus was slowly but surely building up 

 his own herbarium, encouraging students and collectors from all 

 quarters with practical as w^ell as sympathetic help, and inspiring 

 young people to make a beginning, for, he said, a love of Natural 

 History could not fail to be a source of keen delight to them. He 

 was able to secure for his botanical library many valuable works 

 which would now be unprocurable. These include the large folios 

 of Eedout6, Jacquin, Bauer, Andrews, Masson, and others ; also a 

 complete set of the Botanical Magazine, Botanical Begister, Be- 

 fugium Botaniciim, with other old works, as well as most of the 

 modern literature bearing in any way on South African botany.
