Abstract

Iran covers an area of 1.65 m km2 in the SW Asia. Based on climatic variation and geobotanical structure, Iran has the most variation and with about 7864 vascular plant species, is the second richest country after Turkey in SW Asia. Aquatic vascular plants with 23 families contain about 1% of Iran's flora. To prepare the aquatic Flora of Iran and review of its vegetation, as a national project of the Research Institute of Forest and Rangelands (Tehran, Iran), 20 aquatic plant families were studied by the authors. Sampling of specimens was carried out from 238 localities of the aquatic plants during 2008–20 from rivers, wetlands, and other aquatic ecosystems of Iran. In recent years including the present project, 14 taxa have been recorded or described from Iran by the authors and their colleagues. In this research, new identification keys to all aquatic taxa in Iran with descriptions of all species based on morphological studies following the APG IV classification system have been presented. Finally, 33 genera, 66 species, one subspecies, two varieties, and two hybrids belonging to 20 families of three classes including floating, submerged, and emerged plants are described from Iran.

Abstract [Persian]

کشور ایران با مساحت 65/1 میلیون کیلومتر مربع در جنوب‌غربی آسیا واقع شده است. براساس تنوع اقلیمی و ساختار ژئوبوتانیکی، ایران بیشترین تنوع را دارد و با حدود 7864 گونه گیاهی آوندی، دومین کشور غنی پس از ترکیه در جنوب‌غربی آسیا است. گیاهان آوندی آبزی با تعداد 23 تیره، حدود یک درصد از فلور ایران را تشکیل می‌دهند. جهت تهیه فلور آبزی ایران و بررسی پوشش گیاهی آن در طرح ملی مؤسسه جنگل‌ها و مراتع کشور (تهران، ایران)، تعداد 20 تیره گیاهی آبزی توسط نگارندگان مورد بررسی قرار گرفت. نمونه‌برداری از 238 نقطه محل رویشی گیاهان آبزی طی سال‌های 99-1387 از رودخانه‌ها، تالاب‌ها و سایر اکوسیستم‌های آبی ایران انجام شد. در سال‌های اخیر و طی انجام بررسی حاضر، تعداد 14 گونه از ایران توسط نگارندگان و همکاران، ثبت و معرفی شدند. در این تحقیق، کلیدهای شناسایی جدید برای همه آرایه‌های آبزی ایران به همراه توصیف گونه‌ها براساس مطالعات ریخت‌شناسی و استفاده از سیستم رده‌بندی APGIV ارایه می‌شود. در نهایت، تعداد 33 جنس، 66 گونه، یک زیرگونه، دو واریته و دو دورگ متعلق به تعداد 20 تیره از سه گروه گیاهان شناور، گیاهان غوطه‌ور و گیاهان باتلاقی از ایران توصیف شده است.
