ABSTRACT: Filippa, E., Barboza, G. E., Luján, M. C. & Ariza Espinar, L. 1999. Leaf anatomy of the species of Plantago (Plantaginaceae) from Central Argentina. Darwiniana 37(1-2): 1-13.

A comparative study of the leaf anatomy of 10 species of Plantago L. (Plantaginaceae) from Central Argentina was carried out. The analysis included the study of the foliar epidermis, cuticle, stomata and trichomes; a classification of eglandular and glandular trichomes was stablished and original data of the mesophyll structure in 8 species were given as well. Besides, a key based exclusively on leaf features was provided. The results were discussed and evaluated from a taxonomical point of view.

Key words: Plantago, Leaf anatomy, Central Argentina.
