Leclercqia (plant) explained
Leclercqia is a genus of early ligulate lycopsids (clubmosses), known as fossils from the Middle Devonian of Australia, North America, Germany, and Belgium.[1] It has been placed in the Protolepidodendrales.
Species
Distinct species include:
- Leclercqia scolopendra[2]
- Leclercqia uncinata[3]
- Leclercqia andrewsii[4]
There has been question as to whether Leclercqia complexa is assigned to the correct genus; only a poorly preserved specimen exists.[5]
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.[6]
