Treatment. They can be either sprayed or sponged with a 

 soft soap and paraffin soh;tion. 



2. Fungus. 



As previously stated the writer has only seen one case of fungus 

 attack in the Gardens. Both of the plants attacked being members 

 of the genus Cocos (C. plumosa, Lodd. and C. ffexuosa, Mart.). 

 They were attacked by a leaf fungus which caused the leaves to 

 become brown and die off. The following measures were taken to 

 deal Avith the disease. 



Treatment. All the dead leaves, infected leaves and parts of 

 leaves were removed and burnt. The plants were then sprayed 

 with Bordeaux mixture. U]) to the present the plants seem to 

 have completely recovered and are already sending up new leaves. 



Economic Uses. 



The economic value of the palms is widely recognised and 

 the palm family as a whole ranks very high in the list of families 

 of economic value. Apart from the valuable industries of copra, 

 rattans, oils, etc. there are many products which are of great local 

 value and are extremely interesting. Some species seem to be in- 

 valuable and of these Cocos vucifera, L. is an outstanding example. 



The following list, it is hoped, will serve to show how valual)le 

 palms are in the production of many articles in daily use, as well 

 as in the important industries mentioned above. 



The parts of the plant from which they are obtained are also 

 indicated. 



Stem and leaves. — Attaps, Fans, Umbrellas, Baskets, Hats, Mats, 

 Brushes, Wax, Arrows, Spears, Fishing-rods, Sandals, 

 Fancy Articles, Fibre, etc. 



Bud. — Cabbage, used as a vegetal )lo. to the detriment of the plant 

 unfortunately. 



Inflorescence. — Toddy, which is converted into Sugar, Spirit, Vine- 

 gar, etc. 



Fruit. — Copra, Oil, Food, etc. 



Further notes on this important subject will be given with the 



description of each species.
