The timber known as lumbayao has been found in the Manila market 
at various times for some years past, but the botanical status of the 
plant producing it has previously been in doubt. Recently Dr. EL N. 
Whitford and Mr. W. I. Hutchinson, of the Forestry Bureau, encountered 
lumbayao in quantity on a timber concession at Port Banga, District of 
Zamboanga, Mindanao, securing ample material with both flowers and 
fruits, as well as wood specimens from the same trees, and from this 
material it has been possible for me to identify the tree as Tarrietia 
javanica Blume, a species previously known only from Java and Cochin 
China. 
The tree is large, 25 to 45 m in height, usually with a trunk diameter 
of 60 to 80 cm, reaching a maximum of 120 cm. The boles are long 
and clear, reaching in extreme cases a length of 20 to 22 in, and 
frequently have buttress roots, while the bark scales off irregularly. 
(See PL I any! II.) In the Port Banga region the trees occur scat- 
tered, but in some quantity, in a dipteroc-arp forest on or near the tops 
of the ridges of the low coastal hills. 
The wood, according to Miquel, FI. Ind. Bat. 1. c., is “hard and white,” 
Blume in Rumphia 1. c., also speaks of it as hard and white and further 
states that because of its durability in water the natives value it 
for the construction of dugout canoes. Wiesner 1 says that the wood is 
bright- or dark-red, light and easily worked, but not durable, while 
Ivoorders & Yaleton, 1. c., say that it is reddish-brown, strong and durable, 
and much esteemed for the construction of houses. The statements as
