Clade | Family | Ancestral area | Derived area | Reference |
---|---|---|---|---|
Loliinae (fescues) | Poaceae | Eurasia, diploid | Global, polyploid | Inda et al. (2008) |
Santalum (sandalwoods) | Santalaceae | Australia, all diploid | Pacific islands, mostly polyploid | Harbaugh (2008) |
Nicotiana (tobacco) | Solanaceae | South America, most diploid | Africa, Australia, polyploid | Aoki and Ito (2000); Chase et al. (2003) |
Microseris | Asteraceae | Americas, diploid | Australia, allotetraploid | Vijverberg et al. (1999) |
Argyroxiphium (silverswords) | Asteraceae | Americas, diploid | Hawaii, tetraploid | Baldwin and Wagner (2010) |
Lepidium | Brassicaceae | Americas, diploid | Australia, allotetraploid | Mummenhoff et al. (2006) |
Collomia, Naverretia | Polemoniaceae | North America, diploid | Patagonia, allotetraploid | Johnson et al. (2012) |
Polyploidy was inferred based on the chromosome numbers, with allotratraploidy inferred from the formation of bivalents at meiosis.
