Whisk Fern
Psilotum nudumAlso known as Skeleton Fork Fern, Moa
Whisk ferns represent one of the most primitive lineages of vascular plants, easily recognized by their leafless, green, dichotomously branching stems. Instead of true roots, these unusual plants anchor themselves using underground rhizomes that rely on symbiotic mycorrhizal fungi to absorb nutrients. Conspicuous yellow three-lobed spore capsules called synangia form directly along the upper branches during reproduction.
