What are the morphological characteristics of this plant?

Phegopteris decursive-pinnata has pinnately compound fronds where the pinnae are attached to a central rachis that features decurrent bases extending down the stem. The individual leaflets are typically lanceolate in shape and exhibit serrated or lobed margins depending on the specific maturity of the plant. A distinguishing morphological trait is the way the leaf tissue tapers and runs down the petiole, creating a continuous leafy sheath. The texture of the foliage is often slightly leathery, providing structural support to the spreading fronds. These complex vascular structures facilitate efficient nutrient transport throughout the expansive leaf surface.
