Systematics of three North American polyploid arctic alkali grasses ( Puccinellia , Poaceae): morphology, ploidy, and AFLP markersThis paper is one of a selection of papers published in the Special Issue on Systematics Research.
We used flow cytometry, amplified fragment length polymorphisms (AFLP), and macromorphology from field and common garden specimens to delimit and identify parental taxa of three polyploid species of Puccinellia from the North American Arctic.
