What is "aberlemnia"

Aberlemnia is a genus of extinct vascular plants of the Early Devonian (around ), which consisted of leafless stems with terminal spore-forming organs ( sporangia). Fossils found in Scotland were initially described as Cooksonia caledonica. A later review, which included new and more complete fossils from Brazil, showed that the specimens did not fit the circumscription of the genus Cooksonia; accordingly a new genus Aberlemnia was proposed.
