description Foliar architecture of Myrtaceae native species of the Argentinian flora IV. Tribes Myrteae and Metrosidereae and key based on foliar characters. This work completes the leaf architecture of native species of Myrtaceae from Argentina. In this contribution are studied two native genus of the tribe Myrteae with uncertain position in the past, and the only one native genus of tribe Metrosidereae in SouthAmerica. One species of Blepharocalyx and two species of Eugenia are simple, with variable apex and base, leathery texture and entire margin. First vein pinnate, simple and straight, without agrophic veins,second veins broquidodromous, with or without paramarginal and intramarginal veins, third and fourth veins random reticulate or percurrent, and fifth vein random reticulate, percurrent or dichotomized. With or without areoles, with venules branching one, two or more times. The last marginal venation can be complete or incomplete. The leaves of genus Metrosideros are characterized by simple, with acute apex and cuneate base, leathery texture and entire margin. First vein category suprabasal-acrodromous, with agrophic veins, second vein cladodromous or branched, without paramarginal veins and intramarginal veins, and third vein dichotomized. Not develop areoles. Venules branched two or more times. The last marginal venation can be incomplete. Finally, is presented a key to differentiate all native Argentinian species of Myrtaceae, based on characters or character combinations of foliar architecture.

Este trabajo completa la serie sobre de arquitectura foliar de las especies nativas de Mirtáceas Argentinas. En esta contribución se estudian 2 géneros nativos, considerados en el pasado como deposición incierta de la tribu Myrteae, y la única especie de la tribu Metrosidereae nativa de Sudamérica.Una especie de Blepharocalyx y dos especies de Eugenia muestran hojas simples, con ápice y base variables, textura coriácea, margen entero; venación de primera categoría pinnada, simple y recta, sinvenas agróficas; venas secundarias broquidódromas, con o sin venas paramarginal e intramarginal; venas terciarias y cuaternarias reticuladas al azar o percurrentes; venas de quinta categoría reticuladas al azar, percurrentes o dicotomizadas; presentan aréolas; vénulas ramificadas una, dos o más veces; venación última marginal ojalada. Por otro lado, las hojas de Metrosideros son simples, con ápice agudo y base aguda, textura coriácea, margen entero; venas de primera categoría acródroma-suprabasal, con venas agróficas compuestas; venas secundarias cladódromas o ramificadas, sin venas paramarginales ni intramarginales; venas terciarias dicotomizadas, sin aréolas; vénulas ramificadas dos o más veces, y venación última marginal abierta. Se presenta una clave de reconocimiento basada en caracteres o combinaciones de caracteres de arquitectura foliar, que permite diferenciar las especies nativas de Mirtáceas argentinas.
