Why is cotton classified in the mallow family?

Cotton is classified in the mallow family (Malvaceae) because it shares the defining botanical characteristics of that family and the broader order Malvales.

Members of the Malvaceae family, including the genus Gossypium (cotton), are identified by several consistent features:

• Vegetative Traits: They typically possess fibrous bark, alternate leaves with stipules, and often exhibit palmate venation.12
• Floral Structure: The flowers are often showy and frequently feature an epicalyx—a series of bracts that appear as a second, outer calyx.32
• Reproductive Anatomy: The stamens are often numerous and may be fused or arranged in bundles.12
• Fruit and Seeds: The fruits are typically capsular, and a hallmark of many members, including cotton, is the presence of conspicuous hairs on the seeds or the inner walls of the fruit.142

These shared morphological traits, along with genetic and developmental similarities, place cotton firmly within the Malvaceae family.52
