Psilotum nudum (L.) P. Beauv.

Common Name: Whisk Fern, Skeleton Fork Fern
Family: Psilotaceae Kanitz.

Country of Origin: widespread distribution in tropics and subtropics

Description: (syn. P. triquetrum)
Herbaceous perennial devoid of roots, with scale leaves only, and dichotomously branching ribbed stems to 50cm long.
Resembling early vascular plants known from the fossil record, but now considered a fern ally related to the Ophioglossales due to recent genetic evidence suggesting that they have lost many of their original fern-like characters.

Culture: Tropical or subtropical conditions. May benefit from mycorhizal association at least in the gametophyte stage.

USDA Zone: 8a-11
