Origins of cryophilous lineages and the role of Beringia: evidence from the cosmopolitan angiosperm genus Stellaria L. (Caryophyllaceae)
Abstract The cosmopolitan angiosperm genus Stellaria L. (Caryophyllaceae) occurs across the Arctic and is most diverse in the high southern Asian mountains, including presence at the most extreme latitudinal and elevational limits of vascular plants. Using the primary fossil record and double digest...
