    A vegetative key, descriptions, and illustrations for the identification of 182 native and naturalized grasses that occur in Washington, D.C., are presented. In addition, we provide a glossary of terms and indexes to scientific and common names. The key is based on vegetative characters to allow identification of specimens that primarily do not have flowering structures (inflorescences and spikelets).
