***Anisophyton*** was a genus of [Early Devonian](/source/Early_Devonian) land plant with branching axes.[1] Known fossils are of [Emsian](/source/Emsian) age ().[2]

A cladogram published in 2004 by Crane et al. places *Anisophyton* in the core of a [paraphyletic](/source/Paraphyletic) [stem group](/source/Stem_group) of broadly defined "[zosterophylls](/source/Zosterophyll)", basal to the [lycopsids](/source/Lycopodiophyta) (living and extinct clubmosses and relatives).[3]
