| The phylogeneteic relationships in genera Calligonum and Pteropyrum (Polygonaceae) are reconstructed using 30 vegetative and reproductive morphological characters. The data matrix comprised 18 species of Calligonum and 3 species of Pteropyrum plus 2 Atraphaxis species representing outgroups. The analyses were conducted using maximum parsimony approach with characters treated both equally weighted and reweighted by rescaled consistency index. The results revealed that Calligonum is monophyletic. But Pteropyrum is appeared to be monophyletic after reweighting procedure. In both analyses Calligonum is composed of two clades, one is including the winged fruit species (sect. Pterococcus) and the second including the bristled fruit ones(sect. Calligonum) encompassing the monotypic sect. Calliphysa (Calligonum junceum). Of 30 characters analyzed, seven are synapomorphic for both genera. Six characters in Calligonum and one in Pteropyrum were genus specific. The remainder of characters was evolved homoplasiously (or ambiguously) among thsese taxa. | ||

| 21 تاکسون شامل 18 گونه Calligonum و 3 گونه Pteropyrumبعنوان درون گروه به اضافه 2 گونه از Atraphaxis، بعنوان برون گروه با استفاده از30 صفت ریخت شناسی مورد مطالعه قرار گرفتند. در هر دو آنالیز بدون وزندهی و با وزندهی (توسط شاخص سازگاری تصحیح شده)، Calligonum و Pteropyrum تشکیل کلاد مجزا دادهاند. هر دو بخشه Pterococcus و) Calligonum شامل بخشه تک گونهای (Calliphysa از جنس Calligonum تک تبارند. از 30 صفت انالیز شده، 7 صفت پیشرفته مشترک برای هر دو جنس میباشد. شش صفت مختص گونههای Calligonum و یک صفت ویژه Pteropyrum است. بقیه صفات بطور همنما (یا مبهم) در میان این تاکسونها تکامل یافتهاند. | ||
