Similar Species

Dryopteris arguta may be confused with Dryopteris filix-mas, which is a similar species but lacks the long spreading spine-like teeth on pinnules and the lance shaped, chestnut coloured scales on the undersides of pinnae of D. arguta. Scales on pinnae of D. filix-mas are linear or hair-like (Jamison and Douglas 1998).
