Copy of Diary of Mr. C .F .Symington, Forest Botanist, 
for 1C. 10. 34. 
Wednesday 10th . 
Climbed Gunong Stong. The jungle 
above 3000 1 may be divided into three 
classes which blend into one another - 
(1) High hill dipterocarp forest - up to 
3500*. (a) Mountain' oalt forest ~ 3500* - 4C00\ 
(3) Semi-mossy mountain foreslf"- to the 
summit r at 4350' 1 . 
In (1) the following dipterocarps 
were recorded - Hopea sp. (m.mata kuching of 
Penang) tone tree - at 2700 1 ), Hopea" (horbu 
form - quite common up to 3700 1 ), S.Curtisii 
(the most common species up to about 3006" 1 
where S.platyclados became definitely more 
plentiful and continued up to about the 
dipterocarp limit at 3700*). Anisoptera 
laevis was recorded at 2700*; Dipterocarpus 
costatus up to 3000*; Shorea leprosuia at 
3100*;and Vatica perakensis (V.Sl. non King) 
at 3100*. C'th'er' 'conspicuous trees in this 
jungle were a small-leaved Calcphyllum, 
Palaquium rostratum and P.hexandrum . 
As the dipterocarps became scarce, 
species typical of mountain-oak forest 
appeared. These included 3 oaks which I am 
unable to name but one of which appears close 
to the rare Pasania Ridleyana A.Camus. Other 
trees of this* jungle were Schima Noronhae, 
Parinarium rubiginosum, Tristania merguensis, 
Elaeocarpus (2 species), Eugenia spp., 
Podocarpus nerifolius, Pasania 7 sundaica 
and' (at' 360iO f T C amprio sperma auriculata. 
A little higher'were Rhodamnia, Knglehardtia 
Wallichiana, Pasania Y bennettiiR tanarium ? 
rnffW/lDahtirra Y laevigata, G-Iuta sp., 
Fa.san'ia omalokos, Taraktog'enos sp., a 
^inhamoirrum, arid several other Lauraceae. 
Towards 4000* Dacrydium appeared 
and there was a marked falling off in size 
of the trees. The slopes were steep, rock 
was frequently exposed and there was a 
considerable development of moss. The 
species were typically montane, Dacrydium 
being accompanied by Bucklandia, Acantho- 
panax (?), Leptospermum (domlnant~towards the 
summit), Weinmanma, Eugenia Stapfiana, 
Tristania merguensis etc. I n the ground 
Flora there were patches of Sphagnum and a 
few plants of Burmannia . In the immediate 
vicinity of the summit the growth was a 
form of xerophilous scrub with Pandanus, 
very similar indeed to that on the" slopes 
of Gunong Tapis. Here, besides the mountain 
tree species just mentioned we recorded 
Anneslea, Ljtsea ? terminalis, Rhodamnia,
