根据威尔士南部下古红砂岩的森尼层中保存的压痕和挤压化石，描述了一个新的单型属。该新种具有分散的肾形侧生孢子囊，表明与动物叶有亲缘关系，但缺乏解剖学证据。植物的轴的特点是偶尔大的表面突起，有时延伸到可变长度和形态的侧面突起。埋藏因素解释了一些观察到的化石特征，它们在沉积物中不寻常的方向表明，塔雷拉可能生长在暴露的点酒吧。
A new monotypic genus is described from impression and compression fossils preserved in the Senni Beds of the Lower Old Red Sandstone of S Wales. The new species has scattered reniform lateral sporangia suggesting zosterophyll affinity, but supporting anatomical evidence is lacking. The axes of the plant are characterized by occasional large surface protuberances, sometimes extended into lateral projections of variable length and morphology. Taphonomic factors account for some of the observed features of the fossils, and their unusual orientation in the sediment suggests that Tarella may have grown on exposed point bars.
