The frond has the configuration of that of P. sfigittaefolia, the base of the 

 frond being abrupt and the pinnfse being replaced by reflexed and pointed auricles 

 wliich occupy the stipe to the base. D. Bordenii however does not belong, like 

 D. sagitfaefolia, in the group with D. pwrusitica, not having hairy sporangia. 

 The rhizome is oblique, elongatcd, the roots strong, the scales very small 

 lanceolate and twisted.
