Based on earlier molecular DNA studies we recognize 14 native Stipeae genera and one intergeneric hybrid in North America. We provide descriptions, new combinations, and 10 illustrations for species of , , , , , , , and × The following 40 new combinations are made: , , , , , , , , , , , , E.lemmoniissp.pubescens, , , , E.nelsoniissp.dorei, , , E.occidentalisssp.californica, E.occidentalisssp.pubescens, , E.parishiissp.depaupertata, , , , , , , , , ×, , , , , , , , and . A key to the native and introduced genera of North American Stipeae, and an overview of the tribe in North America and worldwide are given. Lectotypes are designated for Nutt., Steud., Bol., Thurb., Pursh, Mez, Link, and Scribn. s.s. and s.s. are now restricted to Eurasia and the Mediterranean/Asia, respectively.
