Phegopteris Dryopteris Subsp. Calcarea

Calcarea brake, scientifically known as Phegopteris dryopteris subsp. calcarea, is a lesser-known fern species native to certain regions of Europe and Asia. This unique plant is characterized by its distinctive fronds that exhibit a calcareous composition, giving it its common name. It thrives in alkaline soils and is often found in rocky or limestone-rich habitats. Despite its ecological significance, Calcarea brake remains underappreciated and poorly studied compared to more widespread fern species. Its delicate appearance and specialized habitat make it an intriguing subject for botanical research and conservation efforts.
