Description of the Woods in the Collection. f,7 



Pores. Visible with the unaided eye on account of their size 

 and white contents, large, conspicuous; mostly single, many pairs 

 Tadially or tangentially sub-divided, and a few groups or nests of 

 4-5 Pores, no linear groups. 



Rays. Difficult to see under any circumstances; less than the 

 width of a Pore apart. 



Rings. Sometimes defined ; boundary (?) a fine line of Soft 

 Tissue. 



Soft Tissue as in Hooroowassa ; simply in sheaths round the 

 Pores; also a fine concentric line (ring-boundary). 



Pith.( ?) 



Radial Section. The Pores are coarse grooves, darker than the 

 ground tissue; many containing dark or ruby resin or gum. 



^ Tangential Section as the Radial, but the Rays need the lens, 

 being minute.

 wood described in 27 a, pp. 84, 86, is not this species.
