Scientific classification e
Kingdom: Plantae
Division: Tracheophytes
Subdivision: Lycophytina
Class: Zosterophyllopsida
Genus: Tarella

Tarella was a genus of Silu-Devonian land plant with branching axes.[1]

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).[2]
