68 CARL SKOTTSBERG, A BOTANICAL SURVEY OF THE FALKLAND ISLANDS. 



F. Aquatic species of ± wide distribution. 



Callitriche antarctica Heleocharis melauostachys Myriophyllum elatinoides 



Crantzia lineata Limosella aquatica Scirpus riparius. 



Heleocharis albibractata Moutia rivularis = 8. 



Group 2. Termopliiloiis element. 



A. Species from S. Chile, sonie of them (P) reaching the Patagonian 

 Channels, but not belonging to South Patagonia or Fuegia. 



P Adiantum cliilense Hydrocotyle hirta Ranunculus acaulis 



Asarca macroptera Ophioglossum crotalophoroides Schizsea fistulosa. 



P Blechuum cbileuse PVPolystichum adiantifornie = 8. 



B. Species, known from the Chilean and Patagonian Cordilleras, but 

 not found in South Patagonia or Fuegia. 



Carex vallis pulchrse Koeleria Bergii 



Draba falklandica Litorella australis 



= i. 



C. Species, also l^nown from the warmer parts of S. America, but 

 not found in Chile: 



Dryopteris filix mas. = 1. 



D. Species widely spread in N. temperate regions, but not known 

 from S. America: 



Dryopteris spinulosa. = 1. 



Group 3. Endemic element. 



Agrostis prostrata Chlorsea Gaudichaudii Leuceria suaveolens 



Arabis macloviana Erigeron incei-tus Nassauvia Gaudichaudii 



Calandrinia Feltonii Gnaphalium antarcticum » serpens 



Carex acaulis Hamadryas argentea Ranunculus trullifolius (?) 



Ghevreulia lycopodioides (?) Hypochoeris arenaria Senecio litoralis. 



= 15. 



The Falkland Islands do not possess any endemic genus. Two of the species 

 enumerated, Arabis macloviana and Senecio litoralis, do not seem to be closely related 

 to any South American species. Agrostis prostrata, Carex acaulis and Gnaphaliwn 

 antarcticum are comparatively little known; no other specimens tlian those from 

 which the original descriptions were made have ever been found. The rest, except 

 Calandrinia Feltonii, have relatives in Patagonia or Fuegia; some have been re- 

 porter] from there, but such statements have, as far as I was able to ascertain, 

 proved fa^se. Banuicnlus tridlifilius is possibly identical with E. monantlios Piiil., 

 of which I hav^e seen no specimens.
