24.2 Cystopteris dickieana Sim<br />

This species is best distinguished by its rugose mammillate<br />

spores and may well prove to be more widespread especially on<br />

northern mountains. This species was described from material<br />

collected in deep shade in an east-facing sea-cave on the<br />

Kincardine (v.c. 91) coast; it has broad pinnae which give it an<br />

attractive appearance hence it is sought after by horticulturists.<br />

Material from elsewhere in Scotland is identical to C.fragilis<br />

except for the non-spiny spores.<br />
