Characteristics
Thelypteris as traditionally defined as a large genus (Morton 1963) is monophyletic (Almeida et al. 2016). Recent taxonomists have split it into multiple genera (Salino et al. 2015; Almeida et al. 2016; PPG 2016). The relevant segregate genera for Florida include Amauropelta (T. resinifera, T. sancta), Amblovenatum (T. opulenta), Christella (T. augescens, T. dentata, T. grandis, T. hispidula, T. kunthii, T. ovata, T. patens), Cyclosorus (T. interrupta), Goniopteris (T. reptans, T. sclerophylla, T. tetragona), Meniscium (T. reticulata, T. serrata), and Thelytperis s.str. (T. palustris). Circumscription and relationships for Christella are still unclear (Almeida et al. 2016).
