(1) A. rubescens Hemsl. Journ. Bot. (1887), p. 204; King,he. 126. 
Tree 60 to 80 ft. tall, 2 ft. or more through, with remarkable 
perforations in the wood formed by peculiar out-growths. Leaves 
sub-coriaceous, elliptic, shortly caudate-acuminate, base cuneate, 
light green; nerves 8 to 10 pairs, prominent beneath; 2*5 to 4 in. 
long, 1-25 in. wide; petioles -25 in. long. Heads -4 in. through, 
3 together on slender peduncles, 1 in. long on a common peduncle 
•5 in. long, pubescent. Hob. Common in forest. Singapore, 
Tanglin; Bukit Timah. Malacca, Ayer Panas (Cantley); Batang, 
Malacca. Selangor, Rantau Panjang (Kloss); Bukit Kutu. Perak, 
Ayer Larut (Wray); Tapah. Penang Hill at about 600 ft. altitude 
(Curtis). Lanka wi. Native name: Merombong. Use: The timber 
is fine, yellow and hard, but owing to the remarkable structure of 
the trunk, is seldom fit to use for building. A curious tree of 
large size at Tapah was a hollow cylinder of lattice work about 
80 ft. tall, and large enough to contain more than one person. The 
perforations were only large enough to admit the hand.
