How to Identify Pteridaceae

Key Identification Features

• The pale upper leaf hairs are often thick enough to give the plant a distinctly woolly appearance from above.
• The dark color of the costa continues into the base of each pinna, with no distinct joint between the pinna stalk and the leaf.
• This dark color extends into the base of leaf segments, with no distinct joint present.
• Each leaf usually has 10 to 14 pairs of pinnae, and the lowest pair is similar in size and shape to the pair above it.
