Morphological, Epidermal and Anatomical Properties of Datura Linn. Leaf in Sana'a City-Yemen and its Taxonomical Significance

The morphological, epidermal and anatomical characters of two wild Datura taxa leaves grown in Sana’a city were investigated. Morphologically; the shape, apex, margin, base, texture, size and venation of lamina were studied. The epidermal characters including the properties of epidermal cells (shape, size & frequency), stomata properties (type of stomata complex, size, frequency, index and ratio) and type of trichomes were determined. Anatomically the characters of mesophyll and main midrib were investigated. The lamina morphological characters of the two studied Datura taxa leaves (shape, base, apex, margin, texture and type of venation) as well as epidermal characters including the properties of epidermal cells (length, size and frequency), stomata properties (size and frequency) & type of trichomes and the anatomical characters ( thickness of Mesophyll and number of abaxial collenchyma layers in the midrib) shows a high significant in taxonomic value for the separation between the two studied Datura taxa .
