Colour. Brownish-white, whitish. Sap-wood. ? 



Anatomical Characters. Transverse section: — 



Pores. Clearly visible, yet scarcely conspicuous on account of 

 the lack of colour : very coarse, size x-2 : little variation : evenly 

 distributed but occasionally gathering into pore-rings : mostly 

 single where scattered, united into compact groups or strings 

 of as many as 13 where crowded : few 9-13 per sq. mm : round : 

 appear whitish in the solid. 



Rays. Just visible, size 3-4 : uniform but rather irregularly 

 spaced : never less than the width of a pore apart and not avoid- 

 ing them : straight : tapering : much denser than the ground- 

 tissue : many 2-4 per mm. : light-brown. 



Rings. Apparently well defined : bands of denser and more 

 porous ground-tissue much resembling annual-rings, also some 

 variation in the number of pores : contour regular. 



Soft-tissue. The whole wood is denser and laxer by turns (in 

 zones) : the whitish lines look like soft-tissue in the solid : also 

 narrow borders of soft- tissue encircling the pores (need micro.). 



Pith. ? 



Radial Section. The pores appear as coarse, open, greyish, 

 usually dull grooves, sometimes shining when empty : the rays 

 as very inconspicuous, faint, almost colourless flakes : the rings 

 are not traceable, but there are bands with varying numbers of 

 pores here and there. 



Tangential Section. As the Radial, but the rays appear as 

 minute, inconspicuous, almost colourless lines about 1 mm. high 

 or less.
