National Museum of Natural History (U.S.). Division of Grasses.

A Section of Grasses was established in the Division of Plants, United States National Museum, in 1912, when the United States Department of Agriculture (USDA) grass herbarium was transferred to the Museum. A.S. Hitchcock, Principal Biologist in charge of Systematic Agrostology,(USDA), was appointed Custodian of the new Section. Hitchcock continued in the position until his death in 1935 and was succeeded by Agnes Chase, another USDA agrostologist.

When the Department of Botany was established in 1947, the Section of Grasses became a Division of the new Department. At that time, Chase became a Research Associate in the Department of Botany and retained her honorary custodianship of the grass herbarium until her death in 1963. Around 1991,the Division of Grasses ceased to be an administrative entity within the Department of Botany.
