Species
editDistinct species include:
There has been question as to whether Leclercqia complexa is assigned to the correct genus; only a poorly preserved specimen exists.[6]
Short lengths of compressed stems of Leclercqia are intermixed among several other plant types in this lens, including remains of Sawdonia ornata and Psilophyton sp. indet.[7]
