BONZANI, NORMA E; BRAVI, VIVIANA S  y  BARBOZA, GLORIA E. Morpho-anatomical study of gynoecium and fruit in Mentha (Lamiaceae) species from Argentina. Caldasia [online]. 2011, vol.33, n.2, pp.349-366. ISSN 0366-5232.

Morphological and anatomical studies on the gynoecium and fruit of Mentha species (sect. Mentha L. and sect. Pulegium (Mill.) Coss. & Germ.) from Argentina were done using optic and scanning electronic microscope. Some novelties on the gynoecium, nectary histology, microsculpture of the nutlets, epicuticular waxes in the hilum and the morphology of the crystalloids are reported for the first time for Mentha. Four types of microsculpture on the surface of the nutlets were established. The results are evaluated from a taxonomical point of view for species delimitation. In addition, myxocarpy is reported for M. citrata, M. x piperita and M. spicata for the first time and its occurrence is discussed.

Palabras clave : Nectary; nutlets; myxocarpy; epicuticular waxes; Mentheae.
