Several varieties of Microsorum ferns, apparently collectively called Strapleaf Ferns, but I have also read some that refer to the one above as Sword Fern or Climbing Bird's Nest Fern (Microsorum punctatum). They have spreading rhizomes, and has generally thick, narrow and shiny yellow green leaves. The tips vary though: from pointed (above), ruffled and twisted (left), and lobed (below).
They produce their own spore case (sporangia) and would cling itself to trees, fern slabs, and practically anywhere i can get moisture and shade. All three are mature enough by now and produce their own spores on the leaves' underside tips.
