Plant Profile: Psilotum nudum

Wisk Fern is a unique, fern-like species native to various regions, distinguished by its absence of common vascular plant characteristics such as leaves and flowers. Instead, it features stems adorned with yellow sporangia that resemble small balls. Frequently regarded as weeds within the nursery sector, these plants can thrive either on the ground or as epiphytes. When growing terrestrially, their stems stand upright, while in epiphytic form, they tend to droop and exhibit a dichotomous branching pattern. The branches are numerous and take on a triangular shape. This pantropical plant is valued for its rarity as a primitive vascular species, although it has the potential to become an invasive weed in greenhouse settings.
