A more delicate species than Muhlenbergia mexicana, often with a more slender inflorescence somewhat resembling M. tenuifloraMuhlenbergia sobolifera (Willd.) Trin. has been found in Essex Co., Ontario, and could occur in southernmost Michigan. Though in aspect more like M. tenuiflora, it would key to M. sylvatica because of its narrow leaves and short anthers, but can be distinguished by having awnless or very short-awned (less than 1 mm) lemmas and short ligules less than 1 mm long.
