process on the back with two or three cilia, inner ones longer, with 
a broad oblong base narrowed abruptly into a slender filamentous 
portion as long as the anther, which has a single process on the back 
ending in two cilia, ivory conic silky hairy style, short cvlindric 
longer than the stameus fruit unknown. 
Obtained on hills on the east coast Pahang. Sanger Davies. 
In foliage this does not resemble any other of our species of 
Shorea. In the form of the stamens it is distinctly like Shorea robusta , 
“Sal ” of Burmah, as also S. utilis king, the Dammar Laut, of Province 
Wellesley, 
Shorea materialis n.sp. Balau Betul. 
The branchlets are black. The leaves ovate with a broad base 
5 inches long and 3 inches wide, (I have also leaf specimens 
probably of this in a young state, 9 inches long, and 5 inches across 
terminated by a long cusp), coriaceous above, smooth polished grey 
when dry beneath, similar in colour, but silvery scaly, nerves obscure 
above and slightly sunk, beneath elevate 10 to 12 pairs ; petiole 
1 inch long scurfy, scaly. Panicle 3 inches long, white scurfy, with 
short branches, pedicels % inch long. Sepals in young fruit oblong, 
obtuse, silky, in half ripe fruit linear oblong red, pubescent 4 deve- 
loped I inch long V\ inch wide, ovary conic, silky. 
This, which gives the best balau timber, was found growing near 
the sea coast at Kuala Balak and Kuala Rom pin by Mr. Sanger 
Davies. 
It resembles to a considerable extent the other species, and it is 
possible that the two plants may be the same. The broad based leaf 
is very unusual in our species but it closely resembles that of 
Shorea robusta. 
As timber trees the Shoreas may be divided into two classes, (I) 
the Serayah class with soft red resinous wood not at all durable and 
as house furniture very liable to the attacks of the house termite 
Calotermes domestica. To this group belong such species as Shorea 
leprosula viz., S. macroptera etc. The name Meranti which properly 
speaking belong, I believe, to species of Hopea is often nowadays 
applied to inferior grades of Serayah. (2) The Dammar laut series, a few 
trees with a very much harder deeper coloured high class timber, the 
type of this group is Shorea utilis King. Damar laut number satu. 
The Balau timber is much nearer allied to this, dark hard close 
grained with fine rays, pores numerous but not too many. 
It seems rather remarkable that in a single genus, there should 
be such a distinction in the timber while at the same time there 
seems to be no other correlation between the plants except that the 
stamens in S. utilis, S. robusta and 5 . materialis are similar in 
possessing ciliated appendages.
