Cyatheales

Published in Frank, A. B. (1877). In: Syn. Pflanzenkd. (Leunis) Ed. 2, 3: 1452, 1456 (Cyatheaceae).

The order Cyatheales, which includes most tree ferns, is a taxonomic order of the fern class, Polypodiopsida. No clear morphological features characterize all of the Cyatheales, but DNA sequence data indicate the order is monophyletic. Some species in the Cyatheales have tree-like growth forms from a vertical rhizome, others have shorter or horizontal expanding rhizomes.
