Notes: FNA24: "Hesperostipa comata subsp. comata grows on well-drained soils of cool deserts, grasslands, and sagebrush associations, at elevations of 200–2500 m. It is widespread and often abundant in western and central North America, particularly in disturbed areas. It is similar to H. neomexicana, differing primarily in having awns that are either not hairy or have hairs that are no more than 0.5 mm long, and in having thinner, longer ligules. Intermediates to H. neomexicana exist but are not common."
