Dicksoniaceae is a group of

Cibotiaceae

.

Description

Species in the family are generally characterized by large pinnate fronds, 1–4 m long. The family includes several species of tree ferns, which grow a single trunk, notably the species in Dicksonia. All members of the family have long, tapering hairs composed of cells arranged end to end, unlike the scales characteristic of the Cyatheaceae s.l.

Evolution

The family is thought to have arisen in the Early Cretaceous, based on molecular evidence. Lophosoria is known from fossil spores and leaf fragments from South America dating to the Aptian. The oldest fossil of Dicksonia is known from the Eocene of Antarctica.^[4] The widespread Jurassic-Cretaceous herbaceous fern genus Coniopteris has historically been assigned to this family, but cladistic analysis suggests that it is more closely related to the Polypodiales.^[5] Relationships of the three living genera, after.^[4]
