worked out Restiacee for the Flora in 1897. (Obituary notice and 
bibliography, Kew Bulletin, 1907, pp. 325-334.) Dr. THEopoRE 
ooKkg, C.1L.E., F.L.S., on the completion in 1908 of his Bombay 
Flora on which he had been engaged for ten years, volunteered 
his aid for the Flora Capensis. He rendered great service by 
filling up many gaps in the present section undisposed of at the 
moment. I had hoped to receive from him more extended contribu- 
tions, but while occupied on Amarantacee he was seized with illness 
which terminated fatally on 5th November, 1910. (Obituary notice, 
Kew Bulletin, 1910, pp. 350-352.) The death of Harry Bo.us, 
D.Se., F.L.S., in England on 25th May, 1911 (obituary notice, 
Kew Bulletin, 1911, pp. 275-277), is something more than the loss 
of a contributor of specialized accomplishments. In his knowledge 
of the South African flora it may be said with confidence that Dr. 
Bouus had no living rival. I cannot do better than quote a few 
words from Professor PEarson’s penetrating appreciation of his 
work and character (Kew Bulletin, 1911, pp. 319-322) :—‘ By 
common consent Dr. BoLus occupied a unique and honoured place 
amongst botanical workers in South Africa. His death removes 
one of the most strikiug figures from the ranks of her scientific 
men, and leaves a vacancy which no man can fill. In the annals of 
South African Botany his name and his record will be written in 
large characters.’ Dr. BoLus took more than a keen interest in 
the progress of this work. As has been acknowledged in previous 
prefaces, Kew has received from him a continuous stream of 
fresh and novel material. Nor can it be doubted that his position 
and af aS in South Africa weighed with the Legislature of 
to it his herbarium and library and a considerable portion of his 
fortune. 
“ From Volume IV. onwards the area comprised in the Flora has 
been extended to the Tropic. In many cf the regions so included 
material is sfnty or wholly wanting. It is therefore with no small 
satisfaction that I am able to record that the Percy SLADEN 
Memorial Expedition (assisted by a grant from the Royal Society 
of London) worked between Ceres Road in Cape Colony and 
Liideritzbucht in Great N amaqualand in the summer of 1908-9, 
‘and a second expedition under the same auspices, between Eende- 
kuil in Cape Colony and Sendling’s (or Bethany) Drift in the 
range River in the summer of 1910-11. The summer flora of the 
he The Natal Government has made no contiibdtion to the work 
since 1907. On the other hand, that of the Transvaal has given 
more substantial one, which it is hoped will provide sufficiently for 
the completion of the work.
