Phylogenetic Analysis of the Genus Pistacia L. (Anacardiaceae) Based on Morphological Data

摘要

Pistacia is an economically important genus because it contains the pistachio crop Pistica vera L. which has edible seeds of considerable commercial importance. The phylogenetic relationships among the species are controversial and not well understood. The phylogeny of Pistacia was revised in detail through the present study. The following taxa are recognized: Pistacia atlantica Desf, Pistica chinensis Bunge subsp. chinensis, Pistica chinensis subsp. falcata (Bess, ex Martinelli) Rech. f., Pistica chinensis subsp. integerrima (J. L. Stew, ex Brandis) Rech. f, Pistica eurycarpa Yalt., Pistica khinjuk Stocks, Pistica lentiscus L. subsp. lentiscus, Pistica lentiscus subsp. emarginata (Engl.) AL-Saghir, Pistica mexicana Humb., Bonpl., and Kunth, P. x saportae Burnat, Pistica terebinthus L., Pistica vera L. and Pistica weinmannifolia Poiss. ex Franch. In conclusion, the study reveals the phylogenetic and taxonomic relationships among Pistacia species. In addition, it shows that the genus is monophyleticand is divided into two sections: section Pistacia and section Lentiscella.
