Scientific classification Edit this classification
Kingdom: Plantae
Clade: Tracheophytes
Clade: Lycophytes
Plesion: †Zosterophylls
Genus: †Deheubarthia

Deheubarthia was a genus of Early Devonian land plant with branching axes.[2]

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