Oricilla was a genus of Early Devonian land plant with branching axes.[2] Fossils have been found from the Pragian to the Emsian (411 to 393 million years ago).[1]

A cladogram published in 2004 by Crane et al. places Oricilla 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 of zosterophylls considered to have indeterminate growth, with fertile branches generally showing circinate vernation (initially curled up).[4] Kenrick and Crane in 1997 also placed the genus in the family Gosslingiaceae, but they place this family in the order Sawdoniales.[5]
