Bmsera BUfiSERACEM 207 



Ih-upe 1-1-6 cm. 1. ; epicarp dark red; nutlet covered with a light pink 

 skin. 



This tree sheds its leaves during March and April, and, after remaining 

 bare for a few weeks, produces its flowers and young leaves. All parts 

 abound with a glutinous balsamic juice of a turpentine odour. The juice 

 forms, on inspissating, a clear transparent gum-resin, "budge gum," of 

 a dark green colour, resembling gum mastic, and capable of being used 

 instead of it as a transparent varnish (Macfadyen). The wood is very 

 light, spongy, poft, a*d weak. Branches planted in the ground quickly 

 and readily grow into tree?, so that they may be used as " grow-posts " to 

 form a fence. The wood, both of this species and of B. simplicifolia, is 

 used for match-sticks in the local match factory.
