Our article makes the cover of Evolution (July 2013)! A Licuala ramsayi stand in northern Queensland, Australia. This is only species found on Australia and is representative of the fantastic radiation in Sahul region of Southeast Asia. In this study we inferred that each of the three genera found in Sahul crossed Wallace's Line only once and relatively recently at about 8.5 Ma. In addition, at least two of the three dispersing genera underwent an elevation in their diversification rate leading to high species richness on each side of Wallacea. Photo by J. Dransfield.
