Discusión taxonómica
Lindsaea lancea is the most common species of the genus in Mexico and distinct by its somewhat falcate pinnae/pinnules and the distal pinnules of a pinna being only slightly reduced. Frond dissection is too variable to distinguish var. falcata (1-pinnate) from other material in Mexico. Nearly half the specimens are 1-pinnate, with some specimens having both 1-pinnate and 2-pinnate fronds.A
