Variation in natural populations of Ruellia caroliniensis (Acanthaceae)

Investigates morphological and genetic variability of Ruellia caroliniensis in Florida. Populations from southern peninsular Florida were the most diverse within populations, while plants from the central part of the species' range were the largest and most robust. The various breeding systems within the species (from allogamous in the south to autogamous in the north) have led to difficulty in determining taxonomic differences within the species. The conclusion that there are distinctive varieties in southern Florida is relevant to determining seed transfer and use zones for this species.
