Genus:	†Tarella

Tarella was a genus of Early Devonian land plant with branching axes.^[2] Fossils came from Pragian age rocks (411 to 408 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]
