Converging local categorization of date palms in Siwa (emic) and genetic categorizations (etic) with the distribution of the named types identified by Isiwan. For genetic analyses, there is a continuum between ethnovariety and local category, while for local farmers, the rationale is quite different (genotype vs. phenotype approaches). For farmers, ethnovarieties imply the idea of identity, when local categories refer to the idea of a qualification (to qualify a date palm of …). Nevertheless, cultivars, ethnovarieties, and local categories are listed by Isiwan as if they were equivalent
