Abstract

Tanacetum tenuissimum is reported as a new record from E Azerbaijan province (NW of Iran). The species by having some characters such as plant height (15–40 cm), length of pappus (0.2–0.4 mm), achene length (1.8–3.2 mm) and ribs (6–10), margin of pappus (crenulate), length and width of capitula (4.5 × 8 mm), and basal leaves (5 × 1 cm) are distinguishable from its close relative T. tabrisianum. In addition, the survey of light and scanning electron microscopy showed pollen grains are tricolporate and echinate (Anthemis-type). Based on the P/E ratio (Polar axis/Equatorial diameter), shape and percentage of the pollen grains were found to be oblate-spheroidal (75%), suboblate (15%), and spheroidal (10%). Distribution map of the new record species and two relatives (T. canescens and
T. tabrisianum) in the world and Iran, morphological and micromorphological characteristics of pollen grains and identification key are presented herewith.

Abstract [Persian]

گونه (Trautv.) Grossh Tanacetum tenuissimum (تیره کاسنی) به عنوان گزارش جدید از شمال‌غرب ایران و استان آذربایجان شرقی گزارش می‌شود. این گونه، با داشتن صفاتی از قبیل طول گیاه (15-40 سانتی‌متر)، طول جقه (4/2-0/0 میلی‌متر)، طول فندقه (2/3-8/1 میلی‌متر)، تعداد رگه‌های فندقه (6-10 عدد)، شکل حاشیه جقه (کنگره‌ای)، طول و عرض کپه (8 × 5/4 میلی‌متر) و طول و عرض برگ‌های قاعده‌ای (1 × 5 سانتی‌متر) از T. tabrisianum که نزدیک‌ترین گونه خویشاوند است، قابل تشخیص می‌باشد. همچنین، بررسی ریزریخت‌شناسی دانه گرده به کمک میکروسکوپ نوری و الکترونی نشان داد دانه‌های گرده از نوع سه شیار-روزنه‌ای و خاردار (تیپ آنتمیس) هستند و براساس نسبت طول قطبی (P) به قطر استوایی (E)، شکل 75% آن‌ها بیضی-دایره‌ایی، 15% تقریبا بیضی و 10% دایره‌ایی است. نقشه پراکندگی این گونه به همراه دو گونه خویشاوند خود (T. canescens و T. tabrisianum) در دنیا و ایران، شرح کامل ریخت‌شناسی گیاه، ریزریخت‌شناسی دانه گرده و کلید شناسایی برای سه گونه ذکر شده، ارایه گردیده است.
