Tamarix hohenackeri bunge, a new record for the flora of Mexico
Tamarix hohenackeri Bunge is reported here for the first time for the flora of Mexico. It also represents the first record for the American continent. This species, native from Asia, was collected along riversides of the river San Salvador (Ensenada, Baja California). A detailed morphological description of the newly reported taxon is provided, and the taxonomic treatment of T. hohenackeri is also discussed. As a result of this study, the presence of six species of the genus Tamarix is confirmed for Mexico, and a dichotomous key for the Tamarix species in Mexico is presented.
