Arthropteris tenella

This common climbing fern has a long creeping rhizome and is usually found growing up tree trunks and over fallen logs and rocks. The frond is from 20-40 cm long and the pinnae (leaves) are arranged in a fishbone pattern. New fronds are bright green, soon turning to a darker green.

Sori are circular and relatively large and held on the underside of the fertile fronds, which are the same shape as the infertile fronds. This fern may be distinguished from the other common climbing fern in the area,

Microsorum scandens, by the stalked pinnae.
