title: [Leaf anatomy study in Solanaceae of Venezuela. V. leaf anatomy of eleven species of Cestrum L] .
abstract: Leaf anatomy of the following eleven species: C. buxifolium Kunth, C. humboldtii Francey, C. lindenii Dunal, C. mariquitense Kunth, C. megalophyllum Dunal, C. olivaceum Francey, C. pariense Steyerm., C petiolare Kunth, C. scandans Vahl, C. strigilatum Ruiz et Pavón and C. tomentosum L.f. is described. Transverse sectioning, bruise and clearing according to the classical methods for optical microscopy were made. The species studied show dissimilitude in relation to a) fohar blade: thickness and sinuosity of epidermal cell walls; type, density and presence of trichornes, leaf type according the position of the stomata, thickness of both palisade and spongy parenchy-ma, number of spongy parenchyma layers, occurrence or not of paranchymatous sheath and sclerifled cells in mesophyll, tmbeculae or projection walls b) Midvein: degree of development and arrangement of the parenchyma and collenchyma, c) Petiole: size and form in transverse section, presence of ornamented cuticle, peridermis and degree of development of the sclerenctiyma next to vascular bundles.
