Habenaria macroceratitis (ventral segment of petals more than twice the length of the dorsal segment; spur terete; of hardwood hammocks) is sometimes recognized as a distinct species (Brown 2000; Batista et al. 2011). Many authors have concluded the differences are confluent and H. macroceratitis should be considered a synonym of H. quinqueseta (Ackerman 2014). A DNA phylogeny found the two entities formed a monophyletic clade (Batista et al. 2013). A range-wide study is needed to determine if H. macroceratitis is an ecotype or a distinct species. Cocytius antaeus was found to visit their flowers (Stewart et al. 2007).
