Dryopteris remota (A. Braun ex Döll) Druce

Scaly buckler fern

Etymology Remota means scattered.
Description Rhizome: erect, branching, scaly.
Frond: 100 cm high by 25 cm wide, deciduous or persistent, monomorphic, blade/stipe ratio: 2:1 to 3:1.
Stipe: grooved, scales triangular to lanceolate, light brown with a dark base, elsewhere described as golden-brown, vascular bundles: 3-7 in a c-shaped pattern.
Blade: 2-pinnate, lanceolate, herbaceous to somewhat leathery, linear to ovate scales below, absent above.
Pinnae: 18 to 22 pair, catadromous; pinnules oblong, shallowly lobed; lower pinnule of the lowest pinnae slightly longer than the upper pinnule; costae grooved above, continuous from rachis to costae; margins margins lobed with acute teeth; veins free, forked.
Sori: round, medial, indusium: reniform, convex, at a sinus, sporangia: brownish.
Culture Habitat: subalpine near forest streams, rare. Distribution: central Europe to western Asia and a couple of stations in Ireland. Hardy to -30°C, USDA Zone 4.

Notes
Parents D. affinis from which it differs in thinner, less leathery texture, finer frond cutting, i.e., pinnule margins lobed, teethed, longer stipes, and scales thinning out more rapidly along the rachis. Differs from the other parent, D. expansa in a narrower frond, narrower, closely spaced, tapering pinnae, densely scaled lower stipe, and convex indusia
