Abstract
Morphology and anatomy of eight species of Huperzia from Arunachal Pradesh was studied here. Following the PPG1 classification the genus Huperzia belongs to the subfamily Huperzioidae under the family Lycopodiaceae of the order Lycopsida which falls under the class Lycopodiopsida. The genus is a medium size evergreen plant with a vertical or ascending stem, with linear toelliptical leaves which are smooth-edged and spores are formed within the sporophylls. Scanning Electron Microscopic studies of the spores were also done. On the basis of all these observations keys to the species were prepared.
