I think it inadvisable to adopt them. Specimens from Gunong 
Tahan differ from the common Malay form in the much thick- 
er and rounder leaves. 
DACRYDIUM. 
Trees often attaining a great size, unisexual. Leaves aci- 
cular, linear or scale-like. Male cones small, scales lanceolate 
with 2 anther cells. Female flowers solitary on the ends of 
the branches. The ovuliferous scale broad rounded free, 
Ovule erect the micropyle pointing upwards. Ripe seed drupa- 
ceous small. 
Leaves of two forms, in young plants acicular. In adults 
seale-like. D. elatum., 
Leaves of one form acicular D. Beccarii. 
Leaves linear falcate D. falciforme.

Common at high altitudes above 2000 feet elevation in 
the mountains of the Northern part of the peninsula, Pahang, 
Gunong Tahan (Robinson, 2354 and 5380) Telom (Ridley), 
Penang Hill (Curtis, 2880), Kedali Peak (Ridley). 
Distribution Tonkin, Tenasserim (Fl. Brit.) Ind Sumatra, 
Borneo, Philippines and Fiji islands. 
The tree is known as Ru Bukit (it. Mountain Casuarina) 
from its resemblance to a Casuarina. It has long been eulti- 
vated in Singapore from Penang hill plants, and there forms a 
large cone-shaped bush, flowering in June. The _ locality 
Singapore Schomburgk,”’ given in the Flora of British India 
is from one of these garden plants. The young tree till it is 
about 14 feet tall, has only the needle like leaves, and is very 
handsome resembling a young spruce fir; full grown trees have 
only the scale leaves, except where pruned on the old wood 
when they produce branches of acicular leaves.
