FOXWORTHY. 
Ceylon woods were taken from Gamble. Those from the Malay Peninsula 
from Ridley and those from the Dutch Indies from Van Eeden and from 
G. J. Filet’s Dictionary of Plant Names. Many of the notes on structure 
are taken from Gamble. 
I have not been able to prepare a key to the different woods of the 
region; but, with the aid of Gamble’s Manual, it has been possible to 
prepare family summaries in some cases. 
The term “seasonal or growth ring” has seemed preferable to “annual 
ring” and so is used. Also the term “pith-ray” is preferred to “medul- 
lary-ray.” 
Unless specially indicated, the structure described is that which is 
seen in the cross section, because it is in this section that the relationship 
of the different elements composing the wood is most clearly, shown. 
The terms “pore” and “vessel” are used interchangeably. 
The structural feature most often noted in the longitudinal section 
of the wood is the numerous parallel transverse lines or “ripple marks.” 
These are due to regularly arranged pitting of the tracheids (see Plate 
XNVI, fig. 55) or to regular arrangement of small pith-rays. The latter 
condition is probably much the less frequent; and, when it occurs, gives 
the appearance of ripple marks only on the tangential section. 
It will be remarked in following through these notes that a common 
or trade name usually applies to more than one species of plant. It 
frequently happens that the wood structure is identical for a large group 
of species. Occasionally the structure is seemingly identical for several 
genera, as in the Ebenacece , which seem to have only one type of structure 
for the whole family. 
The following are the abbreviations which I have found it convenient 
to use in the species notes :
