 hardly folded leaf, the inner 

 face of which lies on the 

 younger stipules and leaves 

 inside. The plaiting of each 

 leaf follows its principal 

 veins: the margins are turn- 

 ed forwards and the surface 

 is finely hairy. The stipules

 margins of those nearest the 

 subtending leaf.
