[Taxacom] Seed plants of Fiji

[Tim Lowrey]

Indeed.  The group of Asteraceae that I work on has a distribution that 
could only result from long distance dispersal in the Pacific Basin.  
How do you explain a distribution of Cook Islands, Hawiian Islands and 
New Guinea+ Australia using vicariance?  There are lots of other plant 
examples. For my group it did not get to Hawaii via a lost continent or 
parts thereof.  There is also an extensive  geologic database, which 
shows the emergence of volcanic islands followed by complete 
submergence with another round of emergence.  That's pretty tough on 
terrestrial plants.  I don't know the geologic history of Fiji but this 
is certainly the case for a number of South Pacific volcanic  islands.
