Morphohistological studies of two forest species of Annonaceae have been reported; the species covered are Xylopia aethiopica (Dunal) A. Rich and X. quintassii Engl. And Diels. Wood fibres range in length from 965 ± 4 µm in X. aethiopica to 853 ± 3 µm X. quintassii. Leaves are hypostomatic with paracytic stomata found only in the lower epidermis. The epidermal cell walls are straight. Epidermal crystals are cluster crystals, which are present in all the species. Communities bordering the Pre-Suhien Forest Reserve notably, Abrafo-Odumase, Mfuom and Ankaako use these plant species for the treatment of stomach and bronchial troubles as well as rheumatism.
