Asplenium anceps
A small, rock-dwelling spleenwort endemic to Macaronesia, close to Asplenium trichomanes but with stiff, leathery fronds and a thick red-brown three-winged rachis. It grows in shaded crevices of volcanic rock and walls in laurel forest and high pine forest on Madeira and the Canary Islands, so it wants cool, humid, shaded conditions and a gritty crevice to root into.
Where it grows wild
Shaded, north- and northwest-facing volcanic rock crevices and old stone walls in laurel forest and high mountain pine forest, rooting among moss and lichen.
Only four records carry an elevation (22–1000 m, median 80 m), and two of those may not be this species. Laurel forest on Madeira and the Canaries lies at roughly 400–1300 m, and the pine forest habitat reaches higher, so its true range is probably mostly mid-elevation.
