Olandraceae

• Arthropteris
• Oleandra
• Psammiosorus

Olandraceae is a family of ferns consisting of three genera containing approximately 60 species. Most are erect ground ferns or scandent epiphytes that start from the ground.

The lamina (leafy area of the fronds) are simple or pinnate, and the individual pinnae are articulate to the rachis. The sporangia are contained in discrete round sori in a single row on either side of the midrib of the fronds.
