Taxonomy Comments: The spelling of the epithet has been disputed. The original spelling of the basionym by J.A. Schultes is Milium mühlenbergianum and the 'ü' is altered to 'ue' under the Shenzhen Code; Muhlenberg variably used a spelling with or without an umlaut and there is no basis in the Code for "correction" of the epithet to 'muhlenbergianum'.
