FEDERATED MALAY STATES. 
No. 6.] JUNE, 1903. [Vol. II. 
JELUTONG. 
Mr. R. Shelford sends from Borneo samples of leaves and 
pods of the Dyera from which the Jelutong of Borneo referred to in 
the Bulletin for March (II. 3) is obtained, together with a sample 
of the product and the stone from which the white powder 
referred to (p. 96) is made. The leaves do not at all resemble 
those of Dr. Haviland’s Jelutong tree, but look like the young 
leaves off a shoot of D. costulata and the pod is quite indistinguish- 
able from that of our species. The leaves are lanceolate and blunt* 
harrowed into the petiole, 12 inches long and over 3 inches wide, 
with about 27 pairs of nerves, glaucous beneath, dull green above, 
petiole 2 inches long, rather slender. The bark is ^ inch thick, 
dark brown and warty. The branches are 5-angled and brown. I 
have little doubt that this is the Dyera Loivii Hook fil but am rather 
doubtful as to whether there is really more than one variable species 
of the genus, 
Mr. Shelford gives the following recipe for the making of the 
gutta ; — 
1 kerosine tin of water; 
1 ,, ,, Jelutong latex ; 
1 pint (approximately) of kerosine oil ; 
1 spoonful of the powdered stone. 
The mixture does not set till the powder is added. The stone 
and gutta were sent by Mr. Ong Tiang Ywee. 
The stone in question is gypsum, sulphate of lime, apparently 
derived from a vein passing through slate. 
It is derived from China.
