to its white color might well be due to the fact that only sap wood had 
been seen. 
In a previous paper 2 I gave a brief account of this wood, but since 
additional material lias been secured, and the identity of the tree estab- 
lished, it seems desirable to give a slightly modified and extended descrip- 
tion of it. 
Sap wood very light-colored. Heartwood light-brown to 'dark-brownish- 
red, soft to moderately hard or hard, moderately heavy. Seasonal rings 
distinct or rather obscure. Usually diffuse-porous (PI. Ill, fig. 1) 
but sometimes falsely ring-porous by reason of traumatic influences 
which have caused an alignment of large vessels at the inner edge of 
a season’s growth. Pith-rays small or moderately large. Vessels medium 
size to large, single or several united, very frequently filled with 
a dark-red substance. Tangential section showing very distinct parallel 
transverse markings. (PI. Ill, fig. 2.) The grain is not perfectly 
straight, but it is not so twisted as to seriously interfere with the working 
of the wood, indeed, the wood is rather easily worked and takes a very 
fine finish. 
There are two other species of Tarrietia known from the Philippines, 
T. sylvatica (Vid.) Men - ., an endemic species and very distinct because 
of its simple leaves, and T. riedeliana Oliver, known from Mindanao and 
Celebes. The former is widely distributed in the Archipelago, and its 
timber is commercially well known. The wood of the latter is unknown, 
but according to the collector’s notes the tree is large and it is probable 
that its timber will prove to be of good quality. 
The occurrence of two such good timbers as dungon ( Tarrietia sylvatica 
( Vid. ) Merr.) and lumbayao ( T . javanica Blume) in the Philippines 
makes the genus one of considerable importance here. Dungon is very 
hard and heavy and is, of course, of the greater importance where strength 
and durability are required. It is a fairly good wood for furniture, but it 
does not take so good a finish as lumbayao, nor is it so easily worked. 
Lumbayao is well suited for the manufacture of furniture, because of 
its color, grain, and the ease with which it is worked. It is particularly 
handsome when quarter-sawed, and should be a very satisfactory wood 
for paneling and cabinet work.
