146 SCIENCE IN AFRICA 



in seven volumes, Flora of Tropical Africa, in eight volumes, and 

 Flora of West Tropical Africa, in three volumes, are amongst the 

 important works on the systematic botany of Africa which have 

 been published at Kew. 



The Bulletin of Miscellaneous Information and other reference 

 works mentioned in the bibliography are also published from the 

 Gardens. Sir Arthur Hill in an article in Nature (1937) has des- 

 cribed the relation of the work at Kew to that in the Dominions and 

 Colonies. 



The Botany Department of the British Museum [Natural History) , under 

 Mr. J. Ramsbottom, who visited South Africa, Rhodesia, and 

 Kenya in 1929, has an herbarium which is second only to Kew 

 among herbaria in the British Empire. It possesses important col- 

 lections from many parts of Africa, including early historic collec- 

 tions from South Africa. The Museum has published several 

 important works on African plants, notably Welwitsch's African 

 plants and Talbot's Nigerian plants (British Museum 1 896-1 901 

 and 1 91 3), and is at present collaborating with the authorities at 

 Coimbra University in Portugal in publishing a flora of Angola, 

 (Carrisso 1937 onwards). Studies on systematic botany relating 

 to Africa by members of the department are numerous, and collec- 

 ting expeditions to the Gulf of Guinea by A. W. Exell, the Sudan 

 by J. E. Dandy, Mount Ruwenzori and other mountains by 

 E. Taylor, and Angola by A. W. Exell, have recently been under- 

 taken by members of the present scientific staff. 



Valuable monographic works have been published by specialists 

 at the Museum. Of these, E. G. Baker's volume on the Leguminosae 

 of Africa, J. E. Dandy's work on Potamogeton, and A. W. Exell's 

 work on the Combretaceae may be mentioned. Further treatises are 

 in hand by G. Taylor {Podostemaceae) and A. G. H. Alston {Sela- 

 ginella) . 



The Imperial Forestry Institute, Oxford, which has a forest botany 

 section including a forestry herbarium, under Dr. J. Burtt Davy, 

 serves as a headquarters in England for that subject. Its work is 

 described in Chapter VII. 



The Imperial Mycological histitute, under Mr. S. F. Ashby, is the 

 central headquarters for the study of all fungi of economic impor- 

 tance. It has recently come under the control of the Executive
