greatest development in the Malayan region. The Philippines, with eleven species, 
show a very rich representation of the genus. The Philippine species show the 
closest relationship to those of Borneo and Celebes. 
All our species except P. polystachyus are mountain, often high mountain, 
forms. P. polystachyus alone comes- down to sea-level and is frequently found in 
rocky places at or near the beach. 
Natural reproduction seems to be easy in most places where representatives 
of this genus are found. 
In P. polystachyus, and possibly other species as well, the young seedlings show 
only 2 cotyledons. 
In some cases, the fleshy receptacle of the fruit is eaten; and there is a very 
limited use made of the wood. Aside from these, the members of the group are 
not used.
