Wisk Fern is a native fern-like plant that lacks many of the typical features of vascular plants like leaves and flowers. They look like stems with yellow sporangia balls. They are often found as weeds in the nursery industry. They can be either terrestrial or epiphytic. Stems are erect when terrestrial, and are often pendulous when epiphytic and branching dichotomous. Branches are numerous and triangular. This plant is pantropical and is prized as a rare primitive vascular plant that can become a noxious weed in greenhouses.
