Blechnum molle is a small fern bearing prostrate sterile fronds with short, broad leaflets. The fertile fronds are erect with widely-spaced, narrow lateral leaflets and a terminal leaflet less than 1/8 the length of the entire frond.
An endemic fern occurring in local populations in the Kermadec Islands and in the central North Island.
Formerly known as Doodia mollis.
