Discussion
Panicum capillare subsp. hillmanii grows in weedy habitats in California, New Mexico, Iowa, Kansas, Oklahoma, and Texas. It may be a southern Great Plains extension of the western plants of subsp. capillare that are sometimes called P. capillare var. occidentale Rydb., but it differs from subsp. capillare in more characters than such plants.
