X^ CARL SKOTTSBERG, A BOTANICAL SURVEY OF THE FALKLAND ISLANDS. 



Generally the cultivated, edible plants have not spread beyond the gardens: Cochlearia 

 ojficiyialis provides an exeeption, for, as I have tried to sliow, it has probably escaped 

 from the old french gardens in Port Egniont. Some species, planted for adornment, 

 as Bellis perennis and Ulex europceus, have spread över the heath and may be en- 

 countered far away from the settlements. Mr. J. J. Felton in Port Stanley told 

 me, that Taraxacum ojjicinale was brought to that place on purpose. The remainder 

 are all weeds and can be divided into two groups. 



1) Species, completely naturalized in the Islands, some abundant already in 

 Gaudichaud's and d'Urville's time: Agrostis alha, caryophyllea and prcecox, 

 Cerastiuni vulgäre, Goronopus didymus, Festuca hromoides, Poa annua and pratensis, 

 Rumex acetosella, Saglna procuniheyis, Senecio vulgaris, Veronica serpyllijolia. 

 Species now very common in some associations are given in spaced ont letters 

 (compare my remarks on the composition of the vegetation). 



2) Weeds in the roads, gardens, potato-fields etc, most of them first recorded 

 by Birger {!): Achillea millefoUwn and tomentosa{t), Agrostemma githago, Agrostis 

 vulgaris, Anthemis arvensis, Anthoxanthuni odoratum, Atriplex sp., Capsella bursa 

 pastoris. Centaurea cyanus, Dactylis glomerata, Geranimn molle, Holcus lanatus, Juncus 

 bufonius and effusus, Leontodon, hispidus, Lolimn perenne, Myosotis arvensis, Plantago 

 lanceolata, Phleum pratense, Ruynex acetosa, crispus and obtusijolius, Sinapis alba, 

 Sonchus oleraceus C^), Trifolium agrarium, hybridum, minus and repens, Urtica urens, 

 Vicia cracca, Viola arvensis. 



I believe, that some of the grasses, as Agrostis alba, Dactylis, Lolium and 

 Phleum were and are still introduced intentionally in order to improve the camp; 

 this is perhaps also tlie case with Trijolium hybridum and repens. I have not been 

 able to get any fnller information on this subject. There are reasons to believe that 

 more and more foreign grasses will be cultivated all över the good camp, which 

 uudoubtedly will come to change the physiognomy of native associations to a con- 

 siderable extent.
