Rhizome short, decumbent. Fronds up to 30 cm., lamina lanceolate, 2-pinnate, pinnules ovate, 1/2-pinnatifid; petiole as long as lamina, slender, naked except for a few thin lanceolate scales at base. Fronds dying completely in winter. Sori as in generic description. Spores ripe 6-9. Usually in crevices of basic rocks, in damp woods and shady places, amongst shady rocks and in caves on mountains, s.l.-3000 m.
Described from Europe (Hb. Linn. 1251/51!).

Very widespread in N. and S. hemispheres. Both rugose and spiny-spored types occur in Turkey. They are not correlated with the morphological types of the frond, nor do they show a distinctive geographical or altitudinal distribution. The rugose spore type is separated by many authors as C. dickeiana Sim.
