clubmoss

Botanical Overview

clubmoss (Lycopodium cernuum) is a flowering plant in the Lycopodiaceae family. This plant has earned a place in traditional medicine through its consistent therapeutic benefits, recorded across multiple cultures. The clubmoss family (Lycopodiaceae) includes evergreen, moss-like plants with creeping stems and upright branches covered in small, scale-like leaves. These ancient plants reproduce by spores rather than seeds. Several species produce alkaloids used in traditional medicine and as sources of clubmoss powder.

General Description

The Hawaiian name for the plant is wāwaeʻiole, or “rat’s foot”. It has a substantial number of scientific synonyms in several genera. The genus Palhinhaea is accepted in the Pteridophyte Phylogeny Group classification of 2016, but not in other classifications which submerge the genus in Lycopodiella. It is the largest of the clubmosses, having rhizomes up to 5 m (16 ft) in length, with leafy uprights up to 2. 5 m in height.
