attendant Malays on the borders of Siam. Extracts from his vivid 
letters home during this period of adventure are given in Scott’s obituary 
notice in the Annals of Botany, vol. xxx, pp. v-x. They show not only 
lively observation, but also a vigorous literary style. Perhaps owing to 
his own delicate sense of duty to the expedition he was with, he made no 
private collection in Siam for the purpose of future work. It is, however, 
an interesting fact that some of the plants which he collected for the 
Skeat Expedition were among the last of the new species determined by 
the veteran Sir Joseph Hooker. In 1909 he attended the British Associa- 
tion Meeting at Winnipeg, making the acquaintance of Canadian forests 
and lakes. Thus as a traveller he had touched three of the great 
geographical areas of the world. 
We have traced Gwynne-Yaughan to Glasgow, where he worked from 
1896 to 1907, as assistant, and later as lecturer in Queen Margaret College. 
In 1902 he co-operated with Professor Bower in producing the second 
edition of Practical Botany for Beginners (Macmillan & Co.), which has 
gone through several reprints. In 1907 he was appointed Head of the 
Botanical Department at Birkbeck College, London, and for two years he 
toiled in formulating elementary and advanced lectures covering the 
whole area of the science. In 1909 he received the appointment as 
Professor in Queen’s University, Belfast. In 1911 he married Dr H. C. I. 
Fraser, herself an accomplished botanist, who had succeeded him in the post 
at Birkbeck College. He was finally transferred from Belfast in 1914 to 
the Chair of Botany in University College, Reading. But he lived only to 
complete one full year of duty there. His health had latterly not been 
good, though he bravely continued his work to the end. He may be said 
to have run in harness till within two months of his death. 
His appreciation among botanists has been quite general. All felt 
the sincerity, the acuteness, the scrupulous care that characterised his 
work. An outspoken critic, he was always ready to help with suggestions 
and with facts, of which he had an uncommon store laid by in very care- 
fully tabulated notes. He became personally known to the general body 
of British botanists by holding office, first as Secretary (1901, 1909-11), 
and later as Recorder (1912-13) of Section K of the British Association. 
Not only was the business of the Section well conducted by him, but he 
had the power of keeping the body of botanists together in friendly 
relations. They will feel that by the death of Gwynne-Yaughan they 
have lost not only a prominent investigator, but also a colleague who had 
a happy power of promoting unity and co-operation. 
Already distinctions had come his way. He was elected to the Linnaean
