Cyrtopus setosus

This species is found in clumps hanging from trees, and sometimes rocks.

It is fine leaved, and looks similar to Echinodium hispidum, but this one always tends to have the shoots curving outwards as you can see in this photo.

It often has capsules visible, and if you look at the leaves under magnification, you will see that the edges are finely serrated whereas Echinodium has no teeth. Another look-alike, Cryptopodium bartramoides, has double teeth.
