The genus Tamarix (Tamaricaceae) in Crete (Greece)

Resumen

A report on the genus Tamarix (Tamaricaceae) in Crete is provided. The previously recorded taxa are compared with new collections made on the island and with vouchers found at different herbaria. Three species were fully confirmed: T. nilotica and T. parviflora, collected in the field, and T. smyrnensis, found only in herbarium vouchers. The other previously reported taxa, T. dalmatica, T. hampeana, T. pallasii and T. tetrandra were not found; T. dalmatica was erroneously reported, the record of T. hampeana represents a fourth species but its identity requires further study, records of T. pallasii are probably misidentifications of T. nilotica and/or T. smyrnensis, and the record of T. tetrandra probably refers to T. parviflora. The presence of T. nilotica is documented, confirming that it has been historically overlooked and mistaken for T. smyrnensis. A morphological comparison between T. nilotica and T. smyrnensis is provided in order to avoid further confusion and misidentifications. A dichotomous key for the Tamarix species reported in Crete is provided.
