Discussion | Melica porteri grows on rocky slopes and in open woods, often near streams. It grows from Colorado and Arizona to central Texas and northern Mexico. Living plants are sometimes confused with Bouteloua curtipendula; the similarity is superficial. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
