a high per cent, of tracheal elements and small quantity of 

 gum-resin. The heartwood is usually small and considerably 

 decayed. The contents of the elements are scarce compared 

 with the red or black woods of other species. Many 

 specimens show thinly streaked heartwood, the black lines 

 of which help to form a pretty pattern (cf. D. quaesita). (See 

 pi. I., fig. 6.)
