Tarella was a genus of Early Devonian land plant with branching axes.{{Cite journal | last1 = Boyce | first1 = C.K. | title = How green was Cooksonia?

A cladogram published in 2004 by Crane et al. places Tarella in the core of a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids (living and extinct clubmosses and relatives).{{Cite journal |last1=Crane |first1=P.R. |last2=Herendeen |first2=P. |last3=Friis |first3=E.M. |year=2004 |title=Fossils and plant phylogeny |journal=American Journal of Botany |volume=91 |pages=1683–99 |doi=10.3732/ajb.91.10.1683 |issue=10 |pmid=21652317|doi-access=free }}

Hao and Xue in 2013 listed the genus as a zosterophyll.
