One of the perennial cultivars was introduced to East Africa and 2000 years ago was being grown by the Meroe people of Nubia who are considered to be the first cotton weavers in Africa. This variety of cotton was spread to other parts of Africa including Kano in Nigeria which from the 9th century became a cotton manufacturing centre. In the wild cotton shrubs can grow up to 10 ft high. The leaves are broad and have three to five or even seven lobes. Flowers are short-stalked. False sepals are large ovate, nearly entire or toothed, heart-shaped at base, long-pointed at tip. Sepal-cup is small, about 5 mm long, cup-shaped, somewhat 5-toothed.
