Discusión taxonómica
According to Kramer (1957), Lindsaea stricta is closely related to L. portoricensis and often difficult to separate from it, the latter having larger segments, thinner texture, and evident veins. These characters, however, do not seem to hold and may reflect a more shaded habitat. Lindsaea portoricensis is here included within L. stricta.
Mexican material belongs to var. stricta. Two other varieties of L. stricta occur in Central and South America, Cuba, and Puerto Rico.
