Lindsaeineae is a
suborder of
ferns (Polypodiopsida),
orderPolypodiales, created by the Pteridophyte Phylogeny Group (2016).[1] It consists of two monogeneric
families plus the larger
Lindsaeaceae with seven
genera, and the suborder contains about 237
species overall.[1] It corresponds to Lindsaeaceae sensu Smith 2016.[2]
Description
The
rhizomes are short to long, creeping but rarely ascending, covered with non-
clathrate scales (rarely hairs). The
petioles are single, rarely double (sometimes several fusing into two in the upper part of the
stipe). They contain
vascular bundles and the
sori are marginal to sub-marginal, generally protected by laminar true indusia (rarely marginal pseudo-indusia or both).[1]
Taxonomy
Lindsaeineae are placed within the Polypodiales and are
phylogenetically related to the other five suborders as shown in this cladogram:[1]
