Curious, leathery, undulating tongue-like (lingua) leaves wave from surface-covering rhizomes. Lithophytic or epiphytic, you can imagine this fern will want good drainage. A natural twist in the leaves reveals a rusty indumentum in fine contrast to the dark green leaf surface. Adaptable as a houseplant.
