Interpretive Summary: Tamarix (saltcedar) is an invasive shrubby weed in Argentina. Previously, there was some confusion over which species were invading, and how to tell them apart. This paper clarifies which species are present, along with their current distribution. Also included are descriptions of these species and a key for distinguishing them.

Technical Abstract: Tamarix species (Tamaricaceae) invading natural and seminatural habitats in Argentina. The genus Tamarix includes species behaving as aggressive invaders in the USA, México and Australia. Previous studies report a variable number of species of this genus cultivated in Argentina as ornamentals,wind-break or for shadow, or growing spontaneously. This work makes clear some confusion related to synonyms and confirms the presence of four species in our country: T. gallica, T. ram'osissima, T.chinensis and T. parviflora, the former three recorded colonizing natural and semi-natural habitats. A description of these species is given, together with a key for their identification, and information of their geographical distribution in Argentina, including maps showing the occurrence of established and invasive populations.
