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



Cop. JuncHS scheuchzerioidcs Spårs. Festuca urenana Sol. Crassula moschuta. 



Senecio candicans Plantago barbata 



These species endure beiiig covered by sand; Juncus and Festuca have enor- 

 mous rhizomes, and also Senecio and, in lesser degree, Plantago and Crassula, are 

 able to grow in spite of the sand. 



Bryopliytes: Didymodon rigidulus, Tortula rubra. 



In West Falklands, on Fox Island, we found considerable thickets of Veronica 

 elliptica growing near the sea on pure, mobile sand, as is shown on plate XIII. 

 This place had probably been covered with tussock grass in former times, and Ve- 

 ronica had accompanied Poa jlabellata, as it does in many places. It had snrvived 

 the destruction of the grass. This I conclude from the great size of the biishes; never 

 have I seen any larger, and they must have been very old. Their heiglit, 1,5 — 2 m., 

 exceeded that of any other specimens that I have seen either in the Falklands or 

 in Tierra del Fuego; but in New Zealand it is reported as growing to a height of 

 about 6 metres. 



Addition. 



P. 50. Calceolaria polyrrhiza Cav. from the Falklands (see Hooker, 8, p. 

 333), is probably a mistake.
