Abstract

Geographical, morphological and taxonomic status of Pistacia khinjuk Stocks ex Stocks in Iran
was revised. A total of 181 accessions (herbarium materials or specifically collected for this study) were
examined geographically and morphologically. The chromosome number of 2n = 24, revealed among 15
accessions studied, was taken as evidence to lump the variability observed in P. khinjuk as one taxonomic
species. However the states of the leaflet number, i.e. 1 (rarely 3) and 3-7 were taken as the key character in order to subdivide the P. khinjuk material in Iran into two varieties: khinjuk (the autonym variety) with 3-7
and populifolia Boiss. with 1 (rarely 3) leaflet in number. The relative illustrations are prepared and
presented. Some nomenclatural corrections are also included.
