SOME IRONBARKS OF NEW SOUTH WALES. 415 



exserted. When the timber is white, the fruits have the 

 raised ring at the edge. 



Timber. — The colour, the first feature to be taken into 

 account in determining this species, ranges from the very 

 palest to a light grey or light chocolate. When first cut 

 it is white, (and in some instances remains so), but on 

 exposure darkens to a grey or light chocolate. 



The Black Ironbark of Port Macquarie often has a number 

 of black streaks and dark patches running through it, but 

 otherwise it is pale. It is straight in the grain, fairly 

 fissile for an ironbark, difficult to season, strong, heavy, 

 compact in texture, durable and suitable for all kinds of 

 heavy constructional and heavy carriage work. 



Anatomical. — A very close compact timber, the fibres 

 appear in a cross section to be compressed into hexagonal 

 shapes, with thick walls, very small lumen filled with a 

 brown deposit. The pores are fairly numerous and 

 scattered irregularly amongst the other wood elements. 

 The vessels are nearly all filled with tyloses ; a feature- of 

 the radial and tangential sections is the numerous and 

 distinct perforations in the fibre walls. The wood paren- 

 chyma is scarce and mostly in the neighbourhood of the 

 vessels, the cells are nearly always filled with a brown 

 deposit, as also are the cells of the ray parenchyma ; the 

 rays are uniformly uniseriate. A few crystals were 



detected.
