abstract: The leaf anatomy of Cestrum acuminatissimum Dunal, C. alternifolium (Jacq.) O.E. Schulz, C. glabrescens (C.V. Morton) Steyerm. et Maguire, C. imbricatum Rusby, C. Iatifolium Lam., C. neblinense D'Arcy et Benítez, C. ruizteranianum Benítez et D'Arcy, C. schulzianum Francey, C. tillettii Benítez et D'Arcy y C. tubulosum Sendtner, is described in order to value its diagnostic characters useful as source of data in the taxonomy of the Solanaceae. The material was obtained from specimens deposited in MY herbarium, coming from different geographical areas of Venezuela, and it was prepared according the classical methodology used in leaf anatomy studies. The results obtained have, besides the common features mentions for other species of the genus Cestrum, some differences in: types and density of trichomes, thickness and sinuousities of the cell wall, stomata position, as well as in the distribution of esclerenchymatous cells of the mesophyll, midvein petiole.
