Genus:

Tarella was a genus of Early Devonian land plant with branching axes.[2] Fossils came from Pragian age rocks (413 to 411 million years ago).[3]

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).[4]
