fertilized by flies the roar of whose wings can often be heard from 
the base of the tree when in flower. The flowers are green, and 
produce a circular flat pod covered with thorns, and containing one 
flat round dark brown seed, with a waxy reddish yellow aril half as 
laige and oblong at the base. This aril is eaten by rats who carry 
about the seeds thus. The tree fruits heavily and seed is readily 
procurable and germinates well, like all good timbers. Saputi is a slow 
though steady grower. The wood though it does not appear to be 
very well-known to timber dealers should be as good at least as 
Merabau and it seems actually harder. It seems well worthy the atten- 
tion of foresters. The tree occurs all over the Peninsula from 
Singapore as far north as Bangtaphan in Siam at least. 
Balau. This timber was formerly reckoned one of the most valuable 
and durable in the peninsula, but of late it has been noticed that the 
timber sold under that flame is by no means as valuable, not lasting 
for more than half as long as the old Balau of the trade. 
The original Balau was a tree belonging to the order Rosaceae 
and known as Pygewn oblongifolium Hook-fil. An account of this timber 
and the tree was published in the first volume of the Bulletin, new 
series p. 144, where the difference between the two timbers known by 
the name Balau is pointed out. 
As there noted the Balau of the present day, which still comes 
from the East Coast of Pahang, whence to a large extent the original 
timber came, is not a Parinarium nor does the plant in the least 
resemble one but is a species of S/zom? ( Dipterocarpaceae .) On several 
occasions leaves of the modern Balau have been sent by forest 
officers but leaves alone are useless generally in identifying speci- 
mens. Recently, however, Mr. Sanger Davies has been able to procure 
specimens of the flowers of one species called Balau Bukit and unripe 
fruits of Balau Betid. 
More complete specimens are required of the ripe fruit of both 
and flowers of the latter species, but the materials are sufficient to 
give an idea of the plants and their relationships to other species. 
Both plants are certainly closely allied together and belong to undes- 
cribed species, so I give as complete a description as I can from the 
materials.
