JUGLANDACE^S. 



This family is not found very abundantly in this region. The few 

 representatives are usually scattered and comparatively unimportant. 

 Pores scattered; pith-rays fine; wavy concentric lines of wood parenchyma. 



Englehardtia serrata Bl. Plate XXII, fig. 4. 



Malaya. 



An easily worked wood of not much importance. 



FAOACE.i:. 



The members of this family arc fairly numerous in the Orient, but 

 they are of comparatively little importance. Many of the species of 

 Quercus furnish a rather inferior quality of wood, which is said not 

 to be durable. Some species are used in India, but their use can not be 

 said io be at all general. Wood brownish, very hard and moderately 

 heavy to heavy, generally with a distinct, darker-colored heartwood. 

 Pores small to large, arranged in radial lines or elongated patches. Sea- 

 sonal rings not distinct. Wood parenchyma in wavy concentric lines 

 and more or less grouped about the vessels. Pith-rays small to very large. 



Quercus. This genus is divided into two groups, according to the size 

 of the pith-rays. First group, all the pith-rays very fine, very numerous, 

 uniform and equidistant. Wood seasons well, does not warp or crack. 

 Second group, pith-rays of two classes, very line and broad, the latter very 

 prominent on a vertical section, making a silver grain of rather large 

 plates. Wood usually warps and splits in seasoning. 



Quercus soleriana Vid. Plate XXII, fig. 5. Catchall (Phil.). 



Philippines. 



Used comparatively little; said not to be durable.

Celtis australis L. 



Southern Europe, tropical and temperate Asia.

Wood gray or yellowish -gray, with streaks of darker color, hard and 

 heavy, tough and strong. Used for tool handles and other implements.

Other species of Celtis furnish wood much like the above and which is used 



for the same purposes.
