The structure, ontogeny, classification, taxonomic significance of trichomes and extra‐floral nectaries in eight cultivars of cotton are described. In all twelve trichome types: 3 main and 10 subtypes of eglandular and one main and 2 subtypes of glandular are described. The type and distribution of trichomes are dependent upon climatic conditions in which the plants are growing. The glandular and eglandular trichomes as well as extra floral nectaries originate from a single papillate trichome or nectary initial respectively. On the basis of trichome studies, the separation of sections Herbacea and Hirsuta seems to be justified.
