Anisophyton

Extinct genus of spore-bearing plants

Anisophyton was a genus of Early Devonian land plant with branching axes.[2] Known fossils are of Emsian age (408 to 393 million years ago).[1]

Quick Facts Scientific classification ...

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