CARL SKOTTSBERG, A BOTANICAL SURVEY OF THE FALKLAND ISLANDS. 



3. The growtli-forms. 



In his paper on the »Arctic and Antarctic Chamsephyte climate», Raunki^r 

 also dealt with the Falkland Islands. Througli the researches of låter years qnite a 

 number of species have been discovered, which were hitherto unknown in the islands, 

 and as the flora is so poor, one might expect that tliey would exert an influence 

 upon the percentages of the various growth-forms. This, and also the fact that I 

 have seen nearly all the species in their native country, have led me to undertake 

 a critical study of the growth-forms in order to see in what degree they may be 

 interpreted as an expression of the Falkland climate. In another paper I have 

 done the same with the flora of South Georgia, where also the Falklands were in- 

 cluded in the discussion. The abbreviations used below are: lii = Nayiophanerophytes, 

 Ch = ChanKBphytes, H = Hemicryptophytes, G = Qeophytes, HH = Helo- and Hydrophytes, 

 Th = Therophytes. The definitions are to be found in Raunki.^r's papers (see Literature). 



In the first column an E designates that the species is evergreen; in the last 

 is put the association, in which the species generally occurs.
