CHARLES BARON CLARKE 875 
1903-4. In addition to these pa sonprioisens to our know- 
ledge of this family, he wrote many papers on the same subject, 
turned to further account in determining the relationship between 
biologic regions and tabulation areas in a paper which appeared in 
Linnean Society’s Journal, ig again made use of his familiarity 
with the Cyperacee in defining the limits of the subsubareas in- 
cluded in the tabulation area of British India 
e, however, Clarke’s attention was, during the nineteen 
years & Ee at Kew, given largely to this sana family, as 
regards which he became the recognized authority, his interest in 
Cyperacee was by no means exclusive. He described the Gesneracea, 
the Acanthacea, and the Commelynacee both for the Flora of Tropical 
Africa and for the Flora Capensis; also the Gentianacee and <Acan- 
where. n 
Clarke visited the Berlin Herbarium in 1897, and worked over the 
material of the family in that collection. One of the last pieces of 
work on which Clarke was engaged was the completion of sagt 8 
Flora of Madeira; his fatal illness overtook him while he 
preparing a memoir of Lowe. His monograph of the ae 
practically complete, is still unpublished. 
A frequent elcome moteitiioe to these pages, Clarke, 
particularly as he advanced in years, became very catholic as 
regards channels of sablieation. His —_ papers are Becuenlly 
piquant, not to say pungent, as well as clear. He grew old with 
infinite grace, and while the pungency aiealy disappeared from his 
contributions, the lucidity remained. The kindest of men, the most 
modest and the most unselfish, he was always ready to help others 
with regard to their work, was a charming host, and a staunch 
riend. 
Clarke joined the Linnean Society in 1867, shortly before the 
loss of his first collection. He joined the Counc e first 
time in 1880, while on deputation at Kew assisting in the pre- 
paration of the Flora of British India; from that time onwards he 
served on the Council wat fg sixteen years, was Vice-President on 
er was Fe 
served on the Council during 1 888-90. be e was a5 alto a Fellow of 
the Geologie! Society.

It was my privilege to reckon Mr. Charles Baron Clarke among 
my friends for close upon twenty years. We saw the more of one

Soon after Mr. Clarke came to live in Kew I had an intro- 
rede to him from one of the closest friends of my undergradua:
