How to interpret P values in partition homogeneity test?

[Robert Wolfgang Rumpf]

I need to compare two different data sets, and have performed a 
partition homogeneity test on them in Paup*.  But I am at a loss as 
to how to interpret the resulting P values - can anyone point me to a 
reference?  Thanks very much...
