From observations which have been made up to the present time 

 in this coimtiy each case of infection has been referable to the 

 presence of a jungle stump. 



The fungus does not apparently fruit in any abundance in this 

 country ; in fact, hitherto it has only been possible to find a single 

 fruit, on camphor, and this a badly developed specimen. The fruit 

 lakes the form of a velvety, brown, in crusted mass on the base of the 

 plant at the collar. In specimens of the fungus which have been exa~ 

 mined on Cacao by the autlior, the brown mass was observed to ring 

 the stem at the collar for a distance of about three inches. In Samoa 

 and in West Africa, tliere appears to have been no difficulty in obtain- 

 ing the fruits of the fungus. The scarcity of fruits in this country 

 would lead one to infer that the propagation of the disease by means 

 of spores is scarcely worthy of serious consideration. 



Treatment. 



When a tree dies it is necessary to remove it with as much of the 

 roots as possible and burn them. 



Old stumps with their roots should also be removed from the 

 infected area and burnt. 



Trenching is unnecessary; and the application of quicklime may 

 be dispensed with, providing that all of the diseased roots have been 

 removed. 



In each centre of infectioil the lateral roots of trees adjacent to 

 the dead tree should be examined and any which are diseased shouFd 

 be cut off to a point where they are healthy, and the diseased portion 

 removed and burnt. 



There appears to be no reason why replanting should not be done 

 immediately after the area occupied by the diseased tree has been dug 

 over and the wood has been removed. 



A DISEASE OF SEEDLINGS OF PALAQUIUM 

 OBLOKGIFOLIUM. 



{LaestadUi Palaqiiii n. sp.) 



By Keith Bancroft, b,a., Assistant MYcoLO(;isr, F,M.S. 



A disease of seedlings of Palaquium oblongifoliiwi, Burck,, has 

 recently been reported from the nurseries of the Forestry Department 

 at Trolak (Perak) w^here a large number of seedlings are said to be 

 iiffected. The plants of Palaquium oblongifoUum are being cultivated 

 iilong with BatanocarpHs maximus (Chengal) ; the latter, however, are 

 not affected.
