*"Xyropteris "Lindsaeaseae contains genera that were formerly considered part of
Dennstaedtiaceae . Molecular data supported the separation of Lindsaeaseae into its own family. Lindsaeaseae is considered the most basal of the orderPolypodiales . Characteristics include: Rhizomes short to long creeping; rhizomes with nonclathrate scales or uniserate 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 [Smith, A. R., K. M. Pryer, et al. (2006). "A classification for extant ferns." Taxon 55(3): 705-731] The genus "Lonchitis" has many morphological characteristics similar toDennstaedtiaceae , but a few characteristics of the spore are similar to the lindsaeoid genera, and molecular data strongly places this genus in Lindsaeaseae [Wolf, P. G. (1997). "Evaluation of atpB Nucleotide Sequences for Phylogenetic Studies of Ferns and Other Pteridophytes." American Journal of Botany 84(10): 1429-1440]References
