Twenty four specimens of prepared staples of cottons, mounted on card within two wooden and glass cases.
The cotton plant (natural order MALVACEA, genus GOSSYPIUM) is widely distributed between 40°N and 30°S. It requires a moist and warm environment. The fibre when matured becomes flattened and has a helical twist amounting to as many as 180 turns per inch. These specimens are representative of the different varieties grown in the world.
