AUTHOR'S POSTSCRIPT. 



The later stages of this work had to be done during 

 a period of illness, and in addition unrest in the press 

 delayed matters and many of the plates and part of the 

 manuscript were not even in first proof before I left India 

 on the necessary furlough. Rao Bahadur K. Ranga 

 Achariyar, whose botanical work is well known in South 

 India, very kindly agreed to see the rest of it through 

 the press, but modestly cut out my reference and thanks 

 from the preface. But the year 1920 was a difficult one 

 in the printing line, and I regret to say that a number of 

 mistakes and misprints occur in the book. I give below 

 the more important. 



Introductory Part. 



In the note on Botanical nomenclature, at the bottom 

 right hand corner, the words one genus should read 

 our species. 



The Key to the Families has been printed in the 

 unfinished state in which I had perforce to leave it. But 

 few references are given to the page in this volume, and 

 in many cases the reference is to the page in volume I 

 without being so indicated. Thus all page references in 

 bracket 2 are to Vol. I. So also in bracket 7, in bracket 25 

 Polygonaceas, brackets 26 and 27 Drpsera, bracket 34 

 Ammannia (which should now read Rotala) and in most 

 of the remaining brackets. The following corrections 

 should also be made : — 



In bracket 3, at end of first line (sedges, etc.) read 74 

 „ I, for 60 read 6/^.
