170 SECTIONAL ADDRESSES 
Prof. Salisbury and their colleagues, the botanical survey of Scolt Head by 
Messrs. Deighton and Clapham—now being greatly extended by Dr. V. J. 
Chapman, the accounts of the vegetation of the Holme Salt Marsh by 
members of the Cambridge Botany School, the investigations on the 
vegetation of the Norfolk Broads by Miss Pallas—again being studied by 
Dr. Godwin and Mr. Turner, and the researches on the plant communities 
of Breckland by Mr. E. P. Farrow, an area which I hope will always remain 
a happy hunting-ground for the botanist and which Dr. A. S. Watt has 
been investigating in great detail for some years. In addition, East Anglia 
is floristically one of the most interesting parts of the British Isles, as is 
evident from Prof. Salisbury’s classical monograph, The East Anglian 
Flora, published through the great enlightenment of the Norfolk and 
Norwich Naturalists’ Society. ‘The same Society sponsored the Flora 
of Norfolk in 1914, which was edited by Mr. W. A. Nicholson and which 
contained an especially interesting chapter on Physiography and Plant 
Distribution by Mr. W. H. Burrell. 
Norfolk has been the home of many famous botanists. Sir Thomas 
Browne, who had great interests in botany, natural history and horticul- 
ture, lived in Norwich for many years before his death in 1682. Sir J. E. 
Smith, who founded the Linnean Society in 1788, was a native of Norwich. 
Sir W. J. Hooker was born in Norwich. The Rev. Kirby Tanner, who 
published a Flora of Norfolk in 1866, died. at Norwich in 1887. Another 
renowned Norfolk botanist and mycologist was Dr. M. C. Cooke who was 
born at Horning and lived in the county until the age of twenty. His 
range of botanical interests was widespread, but he is chiefly remembered 
as an outstanding authority on the Fungi. His Illustrations of British 
Fungi and Mycographia are still indispensable to mycologists. One 
of the most eminent Norfolk naturalists was Dr. C. B. Plowright of King’s 
Lynn, a physician with many scientific interests, who in the latter half of 
the nineteenth century made innumerable contributions to our knowledge 
of the Fungi, especially of the life-histories of the Rusts. His work 
culminated in the publication in 1889 of the Monograph of the British 
Uredinee and Ustilaginee, which for many years was the standard book 
on these groups. It is of interest to know that Dr. Plowright’s son-in-law, 
Mr. T. Petch, the well-known tropical mycologist, is spending his retire- 
ment at North Wootton, near King’s Lynn, where he is still making 
important contributions to mycology, especially as regards entomogenous 
fungi. Mr. H. J. Howard, of the Norwich Museum, is one of the chief 
authorities on the Mycetozoa, Mr. E. A. Ellis of the same Museum is an 
ardent botanist who has recently published a valuable list of the Rust 
Fungi of Norfolk, and Dr. G. Edward Deacon of Brundall is an assiduous 
student of the Fungi who has contributed to our knowledge of the Botrytis 
disease of roses and who has been of great assistance to myself in providing 
material of certain other rose diseases under investigation at Cambridge. 
I propose now to deal with some aspects of plant pathology which I 
hope may be of interest to general botanists. Perhaps, too, it is not 
inappropriate that this address at Norwich should deal with the subject of 
disease in plants, for Norfolk farmers were among the first agriculturists 
to become convinced that barberrry bushes had some influence in the
