Asplenium oblongifolium is a relatively small fern.  It has glossy dark green fronds which can reach about a 1.5 m in length when growing in optimum conditions in open but shaded parts of the forest. In some environments, it can be a dominant and quite conspicuous plant in the forest understory. It is endemic to New Zealand and the Kermadec Islands. It can be found growing on the ground and also in trees.
