Abstract :The current investigation is concerned with the histological features of Senna occidentalis (L.) Link (coffee senna plant). The anatomical structure of different vegetative and reproductive organs was investigated weekly or fortnightly, according to the investigated organ, throughout the growing season. Organs studied included the main root, main stem (represented by shoot apex, apical, and median internodes), different foliage leaves developed on the main stem and on lateral shoots (including lamina and petiole), epidermal peel and trichomes, flower buds, fruits, and seeds. Histological features of various organs of the coffee senna plant were analysed microscopically and photomicrographed. Moreover, ultrastructural features of the seed coat were investigated by scanning electron microscope.
