Genus: Dicksonia

See text.

Dicksonia is a genus of tree ferns in the order Cyatheales. It is regarded as related to Cyathea, but is considered more primitive, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores.

The genus contains 20-25 species, distributed from Mexico to Uruguay and Chile, St. Helena, New Zealand, Australia, Indonesia, New Guinea, and the Philippines. New Guinea has the greatest diversity, with five species.

An easily cultivated species of Dicksonia is D. Antarctica, the soft tree fern.[1]

The genus was first described by Charles Louis L'Héritier de Brutelle in 1788. The name honors James Dickson, a prominent nurseryman and botanist.[1]
