ART IV.] Kama Kao : Jlost Planis of the Sandal Tree. 195 
At the request of Mr. Lushington, the District Forest Officer of 
Aorth Arcot had all trees and shrubs growing within a radius of 
25 feet of 90 healthy sandal trees counted with the following result. 
The average number of trees and shrubs within this space was 
found to be 17 : — 
1. Canthium parviflomm and didymum ...... 3'4 
2. Vitex altissima .......... 1‘6 
3. Acacia pennata .......... 1'6 
4. Phyllauthns . ........ 1'6 
5. Zizyplms CEnoplia - . 1'4 
fi. M allotns philippinensis ........ 1-0 
7. Maba buxifolia 0 8 
8. Diospyros chloi’oxylou ........ 0'7 
9. Strychnoa Nnx-'^omica ........ 0'7 
10. Schleichera trijuga .... .... 06 
11. Other minor shrubs and creepers 3 6 
17-0 
From this enumeration, the District Forest Officer draws the 
conclusion that Canthium farvijiorum and Canthium didymum are 
convenient associates of sandal on the Javadies. On this Mr. 
Lushington remarks that as suspected by him sandal strongly 
favours evergreen scrub growth, the majority of the hosts in the 
above case being of that nature.^ 
13. No conclusion can be drawn from the host plants described 
in the foregoing pages as to the influence exerted on the growth of 
sandal by the species which produce or contain fixed or essential 
oils or balsam, for, there are only about 25 of such species among 
the 144 described and nothing definite is known yet of the effect of 
each of them on sandal. This question merits further investiga- 
tion and research. 
14. It has been suggested to me that a classification of the host 
plants already examined and dealt with in the foregoing pages into 
“ Good,” “ Medium ” and “ Indifferent ” hosts will be desirable 
and useful. Altliough this suggestion is a good one, still, I refrain 
from attempting a classification such as suggested, as it seems to 
me premature to do so on the basis of what is recorded above as a 
result of only a single observation in many cases, until it is verified 
and confirmed. To those who wish to know which of the species 
described by me are good hosts, it would not be tedious to refer to 
the description and find out the information they require.
