see pp. 97-100 for chromosome counts: 33 individuals (15
in Warrior River population, 18 in Cahaba populations, all
n = 32. However they reiterate that in Farmers 1962
study, he did obtain both meiotic and mitotic counts of n
= 16 and 2n = 32, so they now feel that both chromosome numbers
are present, but that n = 32 plants are more common.

counts of n = 16. However the Farmer & Thomas 1969 study
did counts from 18 individuals from Cahaba and all had n =
