Ptisana fraxinea
Ptisana fraxinea is a primordial plant resembling a tree fern, with a thick, woody trunk and a lush canopy of arching, divided fronds. Its tall stature, often exceeding two meters, allows it to thrive under forest canopies, capturing filtered sunlight. Unique kidney-shaped spore cases cluster beneath its fronds, signaling this ancient species' lineage that dates back to prehistoric times.
