Agrostology (from Greek , agrōstis, "type of grass"; and , -logia), sometimes graminology, is the scientific study of the grasses (the family Poaceae, or Gramineae). The grasslike species of the sedge family (Cyperaceae), the rush family (Juncaceae), and the bulrush or cattail family (Typhaceae) are often included with the true grasses in the category of graminoid, although strictly speaking these are not included within the study of agrostology. In contrast to the word graminoid, the words gramineous and graminaceous are normally used to mean "of, or relating to, the true grasses (Poaceae)". Agrostology has importance in the maintenance of wild and grazed grasslands, agriculture (crop plants such as rice, maize, sugarcane, and wheat are grasses, and many types of animal fodder are grasses), urban and environmental horticulture, turfgrass management and sod production, ecology, and conservation. Botanists that made important contributions to agrostology include: Jean Bosser Aimée Antoinette Camus Mary Agnes Chase Eduard Hackel Charles Edward Hubbard A. S. Hitchcock Ernst Gottlieb von Steudel Otto Stapf Joseph Dalton Hooker Norman Loftus Bor Jan-Frits Veldkamp William Derek Clayton Thomas Arthur Cope Grasses Agrostology 01
