The timber known as lumbayao lias been found in tlie Manila market 
^ at various times for some years past, but the botanical status of the 
plant producing it has previously been in doubt. Eecently Dr. H. 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 
fi-uits, 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 si>ecies previously known only from Java and Cochin 
China. 
The tree is large, 2b to 45 m in height, usually witli 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 m, and 
frequently have buttress roots, while the bark scales ol! irregularly. 
(See PL I and II.) In the Port Banga region the trees occur scat- 
tered, but in some quantity, in a diptoroearp forest on or near the tops 
of the ridges of the low coastal hills. 
The wood, according to Miquel, Fl. Ind. Bat. 1. c, is ^^lard and white," 
Blume in Pumphia 1. c, also speak.^ 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 ^ says that the wood is 
bright- or dark-red, liglit and easily worked, but not durable, while 
Koorders & Valeton, 1. c, say that it is reddish-brown, strong and durable, 
and much esteemed for the consti-uction of houses. The statements as
