But-sent BURSEKACE.K 207 



Drupe 1-1-5 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, soft, and weak. Branches planted in the ground quickly 

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

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

 used for match-sticks in the local match factory.
