re NEW AND RARE MALAYAN PLANTS, 37 
On Gunong Semangkok at 4375 feet altitude we have a plant 
much resembling this. Its leaves and branches are glabrous and 
the leaves stiffly coriaceous ovate or oblong ovate acute 3 inches long 
14 inch wide, with only 6 pairs of nerves, which are distant from 
each other, the minute tessellate reticulations so conspicuous In 
typical Rassa, are much less conspicuous. The petiole is a quarter 
of an inch long. ‘The inflorescence terminal is stout, its bark on 
the rachis black and minutely pubescent. The spikes 3 inches 
long and stiff. The male flower bunches are rather distinct. 
The acorns are sessile, with a shallow cup half an inch across, 
x inch deep, with about ten rings; these have the upper edge waved 
with distinct teeth. The glans is a short broad cone half an inch 
long beaked light brown and minutely silky (No. 12061 of my 
collection). The plant growing on the top of the Trig. station 
which of course has been cleared and is now a ered only “with low 
bushes is itself a low bush only a few feet tall. A specimen obtained 
by Barnes from Kluang 'Terbang (10910) resembles this somewhat 
but the leaves are mostly more intermediate between that and those 
of typical Rassa, some however are ovate with fewer nerves, and 
somewhat similar is Kunstler’s No. 6983, from Gunong Hijau in 
the Taiping hills, which he describes as a tree 40 to 46 feet tall. 
This is the plant I take to be King’s var. latifolia. 
With this grows on Gunong Semangkok, a shrubby oak with 
lanceolate long acuminate leaves, which when young are coppery 
red. They are about four inches long and one inch wide. The 
petiole a quarter of an inch long. The young leaves are sprinkled 
all over with stellate hairs and these are densely crowded on the 
midrib and petiole. The adult leaves are nearly glabrous, the 
reticulations are the same in appearance on the upper surface as in 
the Penang fassa, but are inconspicuous on the smooth lower 
surface. ‘lhe branches are covered with a woolly mass of these 
stellate hairs as are the slender weak spikes. This I would call 
the var. /anwginosa. 
Both of these two forms or varieties grow closely intermixed in 
scrubby bushes up to the waist or shorter on the top of the hill, 
but I saw the var. /anuginosa further down the hill about 20 feet 
tall. 
Had I not seen these plants intermixed with intermediate 
fohage, I should certainly have distinguished them specifically, both 
from each other and from O. Rassa, but J would rather class that 
species as a very variable oak varying according to altitude and 
exposure, of the mountain on which it grows.
