Discussion

Dennstaedtia auriculata closely resembles D. arborescens (Willd.) Ekman ex Maxon of the West Indies except the former has lobate fertile segments, lacks laminar buds, and has reflexed basal pinnules, whereas the latter has entire fertile segments, laminar buds, and basal pinnules patent to ascending.A
