Description

Diphasiastrum complanatum is a perennial herb spreading by means of stolons that run along the surface of the ground. Above-ground stems tend to branch within the same geometric plane (hence the specific epithet "complanatum," meaning "same plane"). Strobili are vertical borne in groups of up to 4 at the ends of some of the branches.[9]
