Konioria was a genus of early land plant with branching axes.[2] Known fossils are of Early Devonian age (419 to 393 million years ago).[1]
A cladogram published in 2004 by Crane et al. places Konioria in the core of a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids (living and extinct clubmosses and relatives).[3]
Hao and Xue in 2013 used the absence of terminal sporangia to place the genus in the paraphyletic order Gosslingiales, a group considered to have indeterminate growth, with fertile branches generally showing circinate vernation (initially curled up).[4]
