Huperzia is the largest genus in the Lycopodiaceae family, comprising about 300 species, which are difficult to distinguish because of wide plasticity of the characteristics.
Lycopodium (also known as Tropical Tassel Fern). Not a true fern but a fern relative with pedulous stems and a graceful habit. At the tips of the stems dangle dainty ‘tassels’ where the spores are produced for reproduction. Rare and hard to find, they are epiphytic so do best mounted and enjoy bright light and medium to high humidity. This species has rounded, rope-like stems with a blue-grey cast.
