8 CARL SKOTTSBERG, A BOTANICAL SURVEY OF THR FALKLAND ISLANDS. 



Obs. BoRY has described Tricomanes jlabellula (d'Urville, p. 597) from the 

 Falklands, and låter it has been identified witli T. sibthorpioides Bory from the Isle 

 of Bourbon. I have tried in vain to get the original specimens from the Falklands 

 by communicating with the Museum d'histoire naturelle in Paris; however none could 

 be found. Either the specimens had been referred to this locality by mistake, or 

 the plant was no fern at all; I have gnessed at a small liverwort, Symphyogytia 

 crassifrons Sull., as being identical with T. jlabellula, the specific name of the latter 

 certainl}^ being very suitable for the Symphyogyiia. In spite of diligent search, no 

 visitor has ever rediscovered Bory's species, and I therefore exclude it from my list. 



Serpyllopsis van den Bosch. 



This monotypical genus was reestablished by Christensen (3, p. 28). 



2. S. csespitosa (Gaud.) C. CiiR. (Hymenophyllum csespitosum Gaud., Tri- 

 chomanes csespitosum Hook. Sp. Fil. et auctt. sequent., S. antarctica v. d. Bosch). 



Rocky and stony places, together with Hymenophyllum, falklaiidicum, not com- 

 mon: E. F., quartz-rocks round Stanley! Mt Low ! W. F., Hornby Mts with the 

 former! Weddell Island! Wright says, that this fern is found »on trunks of shrubs»; 

 I do not know where he got this statement, but evidently it is incorrect. — Juan 

 Fernandez, S. Chile, Fuegia. 



Polypodiaceae. 

 Cystopteris Bernh. 



61. €. rragilis (L.) Bernh. 



W. F., SuLLiVAN, Nichol; sheltered places among rocks and large stones: 

 Port Howard! Roy Cove! Westpoint Island, stonerun! Saunders Island (comm. 

 by Mr. W. Benney), — Almost cosmopolitan; also in S. Chile and Fuegia, common 

 in forests. 



Dryopteris Adans. 



I), niix mas (L.) ScHOTT var. eloyigata (Ait.) C. Chr. 



Vallentin, without note on locality (Wright). — Widely spread in temperate 

 regions, also in S. America,^ but hardly found south of Brazil. 



D. spimilosa (MtJLL.) O. K. v. dilatata (Hoffm.) C. Chr. 



W. F., Port North (Mrs. Vallentin 137!) 



Widely spread in temperate regions, but not found in S. America before.
