collections of a particular Jay were invariably dead with before 
he retired to rest for the night, no matter how long the match mav 
have been or how arduous the conditions under which it was 
made. Throughout his life he paid little attention i 
collector of herbaceous plants and of shrubs he lias perhaps never 
been surpassed. 
Prior to and during the period of his deputation in England 
Mr. Clarke published a number <«f papers on boraniral subjects in 
the Journal of the Limwin S^-b-hj and the Journal of )i»tany, 
almost exclusively relating to Indian plants. Here, however, our 
During the rime he was on furlough in En-land (JS77-7'.*), and 
during the subsequent period of his deputation (J87'.>-S;>), he 
elaborated the following natural families for the Flora of Ilrifisl, 
India.— In vol. ii. : Saxifrngarmc, Crassu/aeear, Drnxrraow,

He also prepared, largely at Kew, monographs of the Com- 
nw! itinera* and of rh» (//// > ■<■ / .published in 1881 and lS8d 
respectively, for De Candolle's Suites an Prodrome. 
The group Glumaceae, as numerous notes on specimens in 
the Calcutta Herbarium show, appears to have early attracted 
Mr. Clarke's attention ; as time went on this attention became 
more particularly concentrated on the Gyperaceae. 
He was not able to give much time to the study of this family 
while on duty at Kew between 187'.' and lss;j till towards the close 
of the period, when he published in the iast-nmntmned year, in the 
Linnean Society's Journal, i uus ..t i M lay.a< u- spei s n|
