PREFACE TO PART IV. NervoRK 



BOTANICAL 

 GARDEN 



Being intrusted by the Government of Ceylon with the com- 

 pletion of Dr. Trimen's Hand-book of the Ceylon Flora (left 

 unfinished through the lamented death of the author), I have 

 to render an account of the materials at my disposal for the 

 above purpose. 



Premising that the three Parts already published com- 

 prise three-fifths of the contemplated work, I have towards 

 its completion — 



1. The Natural Order Eiiphorbiacece (by Dr. Trimen), 



nearly ready for press (about 140 species). 



2. A list of the genera and species of all the Orders from 



after Enphorbiacece to Cyperace<2 inclusive, in the 

 sequence in which Dr. Trimen intended to describe 

 them {i.e., in strict accordance with the Flora of 

 British India), together with such synonyms and 

 references as he thought necessary, habitats, native 

 names (few), and occasional notes. For Graniinece, 

 which are to conclude the work, he left no materials 

 whatever. 



3. That portion of the Peradeniya Herbarium which 



comprises the plants not published in Parts I.-HI.; 

 and of the collection of drawings pertaining thereto. 



4. The Ceylon collections in the Kew Herbarium, which 



are much richer than those in that of Peradeniya.
