Lindsaeaceae is a pantropical family of ferns in the order Polypodiales. It contains six or seven genera with about 220 known species, [2] some of which also extend into the more temperate regions of eastern Asia, New Zealand, and South America. [3]
Characteristics include: Rhizomes short to long creeping; rhizomes with nonclathrate scales or uniseriate hairs; blades 1-3 pinnate or more divided; veins usually free; sori marginal or submarginal; indusia open towards margin, sometimes attached at sides, or sori covered by the reflexed segment margin. [4]
For more than a century, these ferns were considered part of the Davalliaceae. Then starting in the mid-twentieth century they began to be transferred to the Dennstaedtiaceae. Molecular data supported the separation of Lindsaeaceae into its own family, which was proposed in 1970. [3] Lindsaeaceae is considered among the most basal of the families in the order Polypodiales. One hypothesis for the relationships within the order is shown in the following cladogram: [5]

The genus Lonchitis has many morphological characteristics similar to Dennstaedtiaceae, but a few characteristics of the spore are similar to the lindsaeoid genera, and molecular data placed this genus in Lindsaeaceae. [6] It is now placed in the related family Lonchitidaceae. [7]
Phylogeny of Lindsaeaceae [8] [9] |
The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized seven genera. [5]
Other sources retain Xyropteris in Lindsaea. [10]
The extinct genus Proodontosoria from the Cenomanian aged Burmese amber of Myanmar has been assigned to the family. [11] Other fossil remains assigned to the family include an indeterminate leaf fragment also from the Burmese amber, [12] as well as a permineralized root from the Albian aged Aspen Shale of Wyoming.

Other genera that have been placed in the Lindsaeaceae are: [7]
