Oak Fern

About

Histiopteris incisa, the bat's wing fern, water fern or fern mata, is a common plant found in Australia, New Zealand and other islands in the south Pacific region. Usually found in moist areas, where it may form large colonies. The lowermost lobes of each pinnae have a bat wing like appearance, giving the fern its common name.

How to spot it

Histiopteris incisa is a medium-sized fern, usually producing fronds of approximately 60–200 cm in length. Fronds are widely spaced, distinct, and slightly dimorphic with fertile lobes slightly narrower than the infertile lobes. Fertile lobes have the sori continuous, linear and exindusiate (without an indusium) but protected by reflexed leaf margins. Young fronds have a thick and whitish blue-green succulent stipe. Mature fronds are thin, long with red-brown stipes. Pinnae are pale greyish-gree
