oblong, five-sided, covered with brown spots, five-celled, 
polysporous. 
Oss. I found this and the following species of Vaccinium 
on the very summit of Gunong Bunko, a remarkably insulated 
mountain in the interior of Bencoolen, commonly called by 
Europeans the Sugar-loaf, in reference to its shape. Its 
elevation is not estimated to exceed three thousand feet, yet 
the character of its vegetation is decidedly alpine. ‘This 
character is probably more marked than it would be at a 
similar height on the side of a differently-shaped hill, owing 
to the steepness which refuses space for large trees, and the 
consequent exposure and want of shelter on its sharp conical 
peak. 
VACCINIUM SUMATRANUM. W.J. 
Racemis axillaribus foliis brevioribus, foliis elliptico-ovatis 
integerrimis coriaceis. 
+ Found on the summit of Gunong Bunko or the Sugar-loaf 
mountain in the interior of Bencoolen. 
A small tree, with reddish-brown bark and smooth branches. 
Leaves alternate, short-petioled, elliptic-ovate, acuminate, 
sometimes obtuse, entire, edges a little reflexed, very smooth, 
firm, stiff and leathery, pale green beneath; about four inches 
long. Stipules none. Racemes axillary, shorter than the 
leaves, often from the stem below them; flowers white, 
pedicellate, alternate. Calyx small, cup-shaped, slightly 
four-toothed. - Corolla oblong-ovate, contracted at the 
mouth; limb short, recurved, four-parted. Stamina eight, 
incluse, inserted on the base of the corol; filaments dilated 
at the base, pilose, tinged with red; anthers two-lobed, 
between which are two short filaments or processes, each 
. lobe prolonged upwards into a membranaceous horn or awn, 
which is bifid at top and opens by a pore. Ovary semi- 
inferior, four-celled, polysporous; ovula attached to the inner 
angles of the cells. Style columnar, a little longer than the 
stamina, incluse. Stigma round, obtuse.
