Discussion
In Florida, Ayenia euphrasiifolia is found in the Florida Keys, south and east of Lake Okeechobee, and near Tampa Bay on the mainland.
Three subspecies, two of them endemic, are recognized in Cuba but are not recognized here; they are based on rather weak morphological characters (habit, vestiture, and
leaf texture) ostensibly correlated with vegetation type and soil substrate. If subspecies are accepted, plants in the flora area are subsp. euphrasiifolia.
Selected References
None.
