don't get excited , it's only a leaf
it does appear obscene but it is just a common leaf. most national serviceman soldiers - which means any male s'porean below the age of 58 - will know the plant from which this leaf comes. during their training in their wooded areas, when they had nothing to do, they could have played with the leaves of this plant. i think this plant is more a shrub than a tree. it is a common plant in singapore.
what is the name of the plant? quite a number of people have blogged about this leaf/plant.
