Leaf with double apex. 
BIXACKAE. 
Pangium edule Reinw. 
Habitat Java. 
Coll. April 1895. 
A young specimen bore a leaf which is nearly as far as the 
base divided into two parts, the latter being bilobate. Along 
the back of the petiole runs a corkline which broadens upwards 
and at the same time sinks in to a shallow groove. Most pro- 
bably the palmatifid leaf has, in a very early stage of develop- 
ment, lost the mid-lobe together with a small slige of the 
petiole and in its further growth covered the wound with 
cork (fig. 41).
