WHITE LAUAN 



This name is applied to those lauans whose wood is not dis- 

 tinctly red. It includes a considerable range in color from white 

 through yellow and gray to pink. The best-known white lauan 

 is furnished by Pentacme contorta (Vid.) Merr. & Rolfe. Pen- 

 tacme mindanerisis Foxw. furnishes the same grade of wood. 



ALMON 



This is a white lauan, whose wood is very light in weight, 

 coarse-grained, and of a light pink color. It is furnished by 

 Shorea eximia (Miq.) Scheff. The wood of bagtican, Parashorea 

 plicata Brandis, is slightly harder than the last. It is usually 

 classed as a white lauan. Mangasinoro and kalunti are some- 

 time classed as white lauans; they are here treated separately, 

 however. Several other species of Shorea, which have pale 

 yellow wood, are classed as white lauans or mangasinoro, ac- 

 cording as their vessels are scattered or arranged in a reticulate 

 pattern. Some of these are: Shorea malaanonan (Blanco) 

 Blume, S. polita Vid., and S. pallida Foxw. 



Collectively, the white lauans rank third in order of abundance 

 of all the Philippine woods. They constitute about 17 per cent 

 of the volume of our forests. 



TANGUILE 



This wood is harder and finer-grained than red lauan, which 

 it very much resembles. It is furnished by Shorea polyspermy, 

 (Blanco) Merr. and, probably also, by S. warburgii Gilg. A 

 closely related form which usually passes for tanguile is tiaong, 

 S. teysmanniana Dyer. It is usually lighter colored and straight- 

 er-grained than S. polysperma, but the difference is exceedingly 

 slight. Tanguile is the fourth most abundant Philippine wood. 

 It makes up about 7 per cent of the volume of the forests. 



GUIJO 



This wood is furnished by Shorea guiso (Blanco) Blume and 

 by one or more undetermined species of Shorea. It is our fifth 

 most abundant wood and makes up about 5 per cent of the 

 volume of the forest. 



YACAL 



This name was first recorded for the wood of Hopea plagata 

 (Blanco) Vid. The woods of other species of this and other 

 genera, which seem to be identical in structure and durability,
