haphazard plantings are carried on, the future of the 
rambai and khapundung fruit will be promising. 
So far as | am aware, no breeding experiments have 
been reported. But it is hoped that plant breeders who 
happen to read this paper may be encouraged to consider 
the problem and its potentialities, so that, in the near 
future, we will have Baccaurea fruits of a larger size, 
sweeter and more palatable taste and smaller seeds and 
that they may be made available with other canned fruits 
every where. 
Pests AND DISEASES 
Since the rambai and hapundung are not yet commer- 
cially important, little attention has been directed to a 
study of the diseases and damages suffered by the plant 
and its fruits. Consequently, our knowledge of those 
aspects of the problem is very meagre. 
Naturally, like other fruit trees, the rambai and hapun- 
dung are liable to damage from parasitic and epiphytic 
plants. he former are the more harmful, for they send 
sucking roots, haustoria, into the vascular system. The 
most injurious of all the parasites, and the most common 
in the cultivated areas, are several species of Loranthus 
(Loranthaceae), the centre of distribution of which, co- 
incidentally, is likewise in western Malesia. These para- 
sitic mistletoes seldom kill their host plants outright, but 
they do considerable damage to the branches on which 
they grow. The only way to combat them is by cutting 
off the branches that are badly affected below the part on 
which the parasites have taken hold. The majority of 
the epiphytes, such as ferns and certain apocynaceous 
species, do little damage. The most injurious are Dry- 
moglossum piloselloides and Dischidia nummularia (Grist, 
1936). 
Insects, especially caterpillars and scale insects, are
