Clarke; Polypodium lineare Bruman, Polypodium dichotomum Thunb. In New Zealand confined to geothermally active sites where it grows on heated soils, sinter field, and around geysers, hot pools, and steam vents.
Fronds up to 0. Stipes glaucous-brown to pale brown, persistent when dead, glabrous, terminated by a bud.

Rachises of fronds in tiers, forking x at narrow angles with a bud terminating each fork, the ultimate branches pinnate, narrowly elliptic, 0. Pinnae linear x 2.
Sori in one row either side of midrib and well away from pinna margins, comprising pairs of sporangia, indusia absent. Distinguished from the distinctly related New Zealand species of Sticherus C. Presl and Gleichenia J.
Smith by its hairyrather than scaly rhizomes, pinnae confined to ultimate branches rather than on all rachis branches, irregularly branched lamina hairs, and by the sporangia in groups linaris rather than in groups of 2, or in rows either side of the midrib. It is the only species of the New Zealand representatives of the family Gleicheniaceae to be completely confined to geothermal sites.
Easy from rooted pieces. Once established grows quickly. Prefers a sunny site in damp soil. Frost and cold sensitive. Natrurally confined to sites of geothermal acitivity within the Taupo Volcanic Zone. Rather tolerant of extreme heat and able to withstand shading.

This species has actively colonised newly created geothermal fields such as Karapiti. It is possible some smaller populations might be threatened by introduced weeds tolerant of heated soils but there is no hard evidence available to confirm this.
