Pteris adscensionis
A critically endangered fern found only on Ascension Island, with fewer than 500 plants left in the wild. Like other Pteris it likely needs mild, misty, constantly moist conditions, from the island's damp upland. Grow it in bright shade with steady humidity and no cold.
Where it grows wild
On arid Ascension, damp habitat is essentially limited to the mist-fed upper slopes of Green Mountain. That is presumably where this fern survives, though our sources did not say. Introduced plants have greatly reduced its habitat.
Not recorded. Ascension's moist zone lies on Green Mountain, which rises to about 860 m.
