Krithodeophyton

Krithodeophyton is a genus of lower Devonian plant with branching axes. It is considered to be a barinophyte.[1][2]

Phylogeny

The phylogenetic position of the barinophytes remains disputed. Kenrick and Crane in 1997 called the group the Barinophytaceae and placed it in their Sawdoniales, well nested within the zosterophylls.[3] Taylor et al. in 2009 considered the barinophytes to be possible lycopsids rather than zosterophylls.[4] Hao and Xue in 2013 suggested that they were not lycopsids, instead falling between this group and the euphyllophytes.[5]
