Those varieties which have the
margin crenated or lobed seem most liable to assume this abnormal
supra-soriferous condition. Among the ferns in which this condition has
been observed are the following: _Scolopendrium vulgare_, _Polypodium
anomalum_, Hook., _Asplenium Trichomanes_, _Cionidium Moorei_.[189]

fructus protulit, deinde deponamus in uberiori terra calidi caldarii,
proferet illa per plures annos multos ac frondosos ramos, sine ullo
fructu. Id quod argumento est, folia inde crescere, unde prius enati
sunt flores; quemadmodum vicissim, quod in folia nunc succrescit, id,
natura ita moderante, in flores mutatur, si eadem arbor iterum in olla
