 and allied genera. 



" The resin which exudes from this tree is very remarkable, 

 as it is transparent and nearly colourless, and that portion of it 

 which adheres to the trees, hangs from them in pendants which

 on wounding, but not so abundantly. 



The sample before me is very like gum thus, or common 

 frankincense, the produce of various species of Pinus, except 

 that it is paler in colour. It is of the colour and lustre of pale

 but internally they are still in a viscid condition, and possess
