INTRODUCTION. 5 
9. Finally I may say that a large number of clerical errors, and 
possibly other oversights still exist in the work. For these I plead for 
forgiveness ; I have had to undertake the work in my leisure hoars, 
often under considerable difficulties in camp, and have had to do it 
practically single handed, for an attempt on two occasions to obtain 
help from my office establishment was disastrous. At the same time I 
cannot commend too highly the work of the typist, and the bulk of 
the work in the Government Press, for a teclinical work of this nature 
must be most difficult to follow. It has been decided that despite such 
errors as may still exist, it is better to get the work into print, and to 
revise it again after a year or two. As regards omissions from the 
list, referred to in paragraph 2,1 hope that in revision this will be 
largely rectified ; and at the same time I hope that, during my retire- 
ment from service, I shall be permitted to take up the herbaceous plants 
on similar lines, so that all plants in the Presidency can find place in 
one or the other list.
