Protobarinophyton
Extinct genus of vascular plants
From Wikipedia, the free encyclopedia
Protobarinophyton was a genus of Silu-Devonian land plant with branching axes. It is placed in a group of early vascular plants (tracheophytes), the barinophytes, a group that has been given various ranks and scientific names.

Phylogeny
Kenrick and Crane in 1997 placed the genus Protobarinophyton along with two species of Barinophyton in the Barinophytaceae in their Sawdoniales, well nested within the zosterophylls.[1] A summary cladogram produced by Crane et al. in 2004, shows Protobarinophyton in the core of a paraphyletic stem group of broadly defined zosterophylls, basal to the lycopsids (living and extinct clubmosses and relatives).[2]

The phylogenetic position of the barinophytes remains disputed. Taylor et al. in 2009 considered the barinophytes to be possible lycopsids rather than zosterophylls.[3] Hao and Xue in 2013 suggested that they were not lycopsids, instead falling between this group and the euphyllophytes.[4]
