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.[2]

Species

Distinct species include:

  • Leclercqia scolopendra[3]
  • Leclercqia uncinata[4]
  • Leclercqia andrewsii[5]

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]
