Discussion
Subspecies 2 (1 in the flora).
Within Piriqueta, P. cistoides has the widest distribution. Both subspecies show wide morphological variation; subsp. cistoides is homostylous and self compatible; subsp. caroliniana is distylous and self incompatible. In Cuba, Dominican Republic, and northern South America, intermediate specimens (10% of the total) cannot be assigned morphologically to one subspecies or the other. R. Ornduff (1970c) made crosses between and among the subspecies; he found no reproductive barriers among the different morphs of subsp. caroliniana; the fertility of the hybrids between both subspecies was higher than that of the hybrids among populations of subsp. cistoides. Subspecies cistoides has been reported from Georgia; the author has not seen specimens.
