under great obligations for frequent valuable communications, 

 and for specimens of plants from their respective places of resi- 

 dence. It gives me great pleasure, too, to record tbe uniform 

 courtesy and kindness with which tlie gentlemen, holding the im- 

 portant and influential positions of Government Agents, have as- 

 sisted me in carrying out the objects I had in view, when making 

 botanical tours through their respective provinces or districts, 



I would wish to associate with this little book the names of 

 Harmanis de Alwis Modliar, and of Don Seman De Silva Aratchy, 

 native officers, employed during many years in this establishment, 

 the former as Draftsman, and the latter as Principal Tlant-col- 

 lector, to whose intelligent and hearty co-operation is due much of 

 my success in procuring new and rare species of plants from the 

 jungles. 



Some apology may be considered necessary for the length of 

 time that has elapsed since the present work was commenced, but 

 a large portion of that time has been occupied in researches con- 

 nected with it, and these researches have, it is hoped, tended to 

 make it more useful and more worthy of being laid before the 

 scientific world.
