Authority. Nilson (85) p. 124. 



Colour. Light brown or pink, quite uniform. 



Pores. Upon the limit of vision, size 4-5, little variation : 

 evenly distributed, occasionally a narrow zone poor in pores : 

 numerous, 40-90 per sq. mm. : arranged radially : many single, 

 pairs, and subdivided in groups of as many as 8 : oval : empty. 



Rays. Upon the limit of vision, size 5-6 : in appearance two 

 sizes, but the smaller are the attenuated ends ; uniform ; equi- 

 distant but apparently many small between the large ones ; 

 "ends" a pore-width apart; "middles" much more: together 

 about 12 per mm. : very lax and large-celled. 



Rings. Very faint, by no means clear : the boundary only 

 occasionally visible as a vague, darker band or a zone poor in 

 pores : much less distinct with lens than appears to the naked 

 eye. 



Pith. ? 



Radial Section. Pores visible but very fine and inconspicuous : 

 no contrast : the rays need the lens and are slightly pinker, 

 minute, inconspicuous flakes : the rings are just traceable with 

 care. 



Tangential Section. As the Radial, but the rays are minute, 

 inconspicuous, pinkish lines about 0*2 mm. high. 



Type specimen authenticated by the Sydney Technological 

 Museum.
