Its affinity is with P. areolata, and except for the non-areolate 

 leaves, we should conclude from the description, that the 2 

 species are identical. Merrill gives some other points of difference, 

 such as the ..somewhat longer petioles" and „the somewhat 

 larger flowers" in P. Williamsii. We cannot decide, not having 

 seen any specimen of the latter species, but the given differences 

 do not seem very important, since we found also that in P. 

 areolata the ..areolae" not always are very conspicuous.
