| چکیده | ||
| The genus Rotala L. is one of the largest genera in the family Lythraceae. In the present study, anatomical features of the stem and leaf of selected species of the genus Rotala were investigated. The selected taxa chosen for the present study include R. baileyana, R. deniflora, R. macrandra, R. malabarica, R. malampuzhensis, R. mexicana, R. occultiflora, and R. tulunadensis. Moreover, these species were also distributed in the North Malabar regions of Kerala. The results of this study revealed that all examined taxa shared nearly identical anatomical characteristics, but some showed few remarkable differences. According to the result, cortical cells and the nature of vascular bundles vary in different species. The species can be distinguished based on aerenchyma cells in the inner cortex, vascular bundles, the presence of calcium crystals, and the layer of palisade tissue. An identification key to the taxa was also provided based on the anatomical features of their leaf and stems. | ||

| چکیده [English] | ||
| جنس Rotala L. یکی از بزرگترین جنس‌های خانواده Lythraceae است. در مطالعه حاضر صفات تشریحی ساقه و برگ تعدادی از گونه‌های این جنس شامل R. baileyana, R. deniflora, R. macrandra, R. malabarica, R. malampuzhensis, R. mexicana, R. occultiflora, وR. tulunadensis مورد بررسی قرار گرفتند. این گونه‌ها در شمال منطقه مالبر در کرالا حضور دارند. نتایج این بررسی نشان داد تقریباً همه گونه‌های مطالعه شده صفات تشریحی مشترکی دارند، اما بعضی گونه‌ها تفاوت‌های قابل ملاحظه‌ای را نشان می‌دهند. براساس نتایج این تحقیق سلول‌های پوسته و دستجات آوندی در گونه‌های مختلف اشکال متفاوتی دارند. گونه‌ها بر اساس سلول‌های آئرانشیمی کورتکس داخلی، دستجات آوندی و حضور کریستال‌های کلسیم و لایه‌های بافت پوششی کلروپلاستی از هم قابل تفکیک هستند. همچنین یک کلید شناسایی برای گونه‌های بررسی شده براساس صفات تشریحی برگ و ساقه ارایه می‌گردد. | ||
