Charles Edward Moss (February 7, 1870 Hyde, Cheshire – November 11, 1930 Johannesburg), was an English-born South African botanist, the youngest son of a nonconformist minister, and is noted for being the editor of the first two parts of The Cambridge British Flora published in 1914 and 1920. The Cambridge British Flora, under the editorship of Moss, was intended to be a ten-volume survey of the flora of Britain, with contributions by specialists in particular genera. The two volumes that saw publication were of a very high standard, but the project was subsequently abandoned.
