preparation. Schonland has worked up one of the most important 

 iamilies of succulents, the Crassulaccac, and has revised the genus 

 Rhus and is making a study of the Cypcraceae. Mrs. Bolus is 

 studying the Mcsembiyanthonuiiis, while Pillans, another worker 

 in the South Western area, is busy with the Restiaccae. Phillips 

 has added to our knowledge of the S.A. Proteaceae and has pub- 

 lished monographs on the genera Calpvrnia, Cyphia and Borbonia; 

 in collaboration with Kotze he has reviewed the genus Faurea, 

 and Pteronia in collaboration with Hutchinson. Miss Verdoorn, 

 one of the assistants in the National Herbarium, has worked on the 

 Transvaal Primnlines and the genus Fagara. From the economic 

 standpoint one of the most important pieces of work is the veld 

 burning experiments which Pliillips has in hand at Groeiikloof, 

 near Pretoria, and on which he has published a preliminary 

 report. Also' of great importance from an economic standpoint 

 is the work which is being carried out by Miss Stent on indigenous 

 grasses and their distribution throughout the Union and on the 

 plants poisonous to stock. 



In addition tO' the workers mentioned above who are making 

 a study of the distribution and classification of plants, there are 

 a large number of enthusiastic and careful collectors who have 

 rendered valuable assistance and who have donated their 

 collections to public institutions. One of the foremost of these 

 is Mr. E. E. Galpin, who has presented his unique herbarium of 

 Transvaal and Cape plants to the National Herbarium and is now 

 making further collections and studying the vegetation of the 

 Waterberg District of the Transvaal. Amongst numerous other 

 collectors might be mentioned Madame Dieterlen whose 

 Basutoland plants form an invaluable addition to the National 

 Herbarium, and ]Madame Borle and the Rev. Junod who are 

 making exhaustive collections in Portuguese East Africa. Dr. 

 Eattray, Miss Guthrie, and J. D. Keet have made their 

 contributions from the Cape Province, Pierce is collecting in 

 Swaziland, IMogg is specialising in areas, where cattle diseases are 

 prevalent, E. G. Bryant, Mrs. Jones, and Miss McCallum are 

 keenly interested in Transvaal plants, Potgieter and Putterill 

 have done useful work in the Free State, and Archdeacon Rogers 

 is well known as an enthusiastic and intelligent collector. Mr. 

 F'red Eyles has added very considerably to O'ur knowledge of the 

 flora of Rhodesia and has published a valuable list of the plants 

 known to occur in that country. 



Although the bulk of the work accomplished has been in 

 connection with the phanerogamic flora, the study of the 

 cryptograms has. not been altogether neglected. Sim is making a 

 study of the mosses and hepatics and has published the first 

 section of his monograph on the subject. A study of the fungi 

 of the country is greatly facilitated by the unique and invaluable 

 collection in the cryptogamic section of the National Herbarium, 

 which is assuming vast proportions under the care of Miss 

 Bottomley. I have continued my study of the rust fungi, having 

 published a paper on the rusts affecting the Compositae, and in 

 collaboration witli jNIiss Boftomlev have written on the genera
