Asplenium schizotrichum
A critically endangered spleenwort of Rarotonga (Cook Islands) and Niue, described by Copeland in 1931; fewer than 20 mature plants are thought to survive on Rarotonga. It grows low down in shaded, humid valleys, on boulders above streams, on clay banks and on rotting logs in forest. It is almost never in cultivation, and any plants should come only from conservation spore propagation.
Where it grows wild
On Rarotonga it has been collected in the Totokoitu, Papua and Tupapa valleys: in valley-bottom Hibiscus forest on a steep bank by a track, on clay banks by the Totokoitu stream, and on a large boulder above a stream under a light forest canopy. On Niue it was collected on rotten logs in moist, deep forest south of Alofi. It is a shade fern of humid valley floors, growing on soil banks, rock and decaying wood.
Recorded at about 20-100 m: 90-100 m in Rarotonga's valleys and about 20 m on Niue.
