11. Austral-circumpolar element. — 3 sp. (20%). 



a. Endemic: Polystichum Fuentesii. 



h. Not endemic: Asplenium obliquum, Ophioglossum lusitanicum subsp. 

 coriaceum. 



III. Neotropical element. — i sp. (6.7 %). 



Endemic: Dryopteris Espinosai. 



We find the same dominance of a palaeotropical element as among the an- 

 giosperms. Ophioglossum Itisitanicuni is reported from Atlantic Europe, the Medi- 

 terranean and Macaronesia, whereas the subspecies is austral-bicentric, an example 

 of a remarkable discontinuous distribution. The American element is represented 

 by a single endemic species and there is no fern corresponding to Polygofiiim 

 acianinatum and Scirpus rip anus. Polystichum Fuentesii and Asplejiium obliquum 

 are, perhaps, Antarctic, and the latter was classified as such above (p. 282), but it 

 is a seaside plant. If we follow Cdpeland, Asploiium, Doodia and Davallia are of 

 Antarctic origin.
