ʻē.kaha
n.
1. The bird's-nest fern (Asplenium nidus), widespread in the tropics, forming large rosettes and in some forests perching on branches of trees. The fronds are large, entire, sword-shaped. The black midrib is used like the ʻamaʻu fern for decorating pandanus hats. (Neal 21.) Also ʻākaha. This fern is sometimes called ʻēkaha kuahiwi, mountain ʻēkaha, to distinguish it from the mosses or from ʻēkaha kū moana. (PCP ke(e)ta(f,s)a.)
2. A moss growing on rotted trees. Also limu ʻēkaha.
3. Same as ʻēkaha kū moana.
