Protobarinophyton

Protobarinophyton
Scientific classification
Kingdom: Plantae
Division: Tracheophyta
Subdivision: Lycophytina
Class: †Zosterophyllopsida
Genus: †Protobarinophyton

Protobarinophyton was a genus of Silu-Devonian land plant with branching axes.[1]

A cladogram published in 2004 by Crane et al. places Protobarinophyton in the core of a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids (living and extinct clubmosses and relatives).[2]
