Other claims from this paper (4)
- Observation Spanish Pteridium plants did not differ significantly from P. aquilinum morphologically.
- Observation Spanish Pteridium sporophytes yielded a chromosome count of 104, typical for the genus.
- Observation Isozyme electrophoresis of Spanish and British Pteridium yielded a genetic identity of 0.86, within intraspecific distances found in other ferns.
- Observation The authors conclude there are no grounds for accepting a form of Pteridium distinguishable from P. aquilinum in the Sierra de Cazorla region of southern Spain.
