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



a. luidemic: Polysticluim Fuentesii. 



b. Not endemic: Asj)leniiini obliquum, Ophioglossum lusitanicum subsp. 

 coriaceum. 



III. Neotropical element. — i sj). {6.7 %). 

 luidemic: Dryopteris l^^.spinosai. 



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

 (^iosperms. OpJiioglossum Iusita)iicu})i 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 Polygo7ium 

 acuDiJiiaiuDi and Scirpus ripariiis. Polystichinn Fuentesii and Asple7nwn obliquiwi 

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

 is a seaside plant. If we follow CoPEl.AXi), Aspleimmi, Doodia and Davallia are of 

 Antarctic origin.
