This species ia endemic in tbe Philippines, and as now represented iu the 
liorbarinm of the Buroan of Science is decidedly polyTnnrpliic. There seem to be 
tlirce more or less distinct types, but with characters not sufTiciently constant 
to justify specific segregation, altliough the two extremes ai-e apparently very 
easily distinguished. 
The typical specimens, including both of the Cuming collections on wliicU 
the species was originally baaed, have a very lax inflorescence, with ccinpnnitively 
long and slender pedicels, the petals seem always to number 5, and at the base 
are narrowed into a distinct claw. 
The other extreme type has both calyx-lobes and petals almost always 4, the 
influrescence is more condensed, the pedicels are shorter and stouter, the petals 
are usually broader and at their base either do not form a definite claw, or the 
claw is vory short. These are known only from Mindanao. 
T'niting these, however, is a third set, from Mindanao and Basilan, with the 
petals usually 4, but on an oiu-asjimal sheet with alwmt one-third of the (lowers
