A new distribution area of verbascum stenostachyum Hub.-Mor. (Scrophulariaceae) from Bursa (Turkey) and contributions on its micromorphological, anatomical and palynological properties

Abstract

This study aims to obtain detailed information about the morphological, micromorphological, anatomical and palynological characteristics of the Verbascum stenostachyum Hub. Mor., which is reported for the first time to the flora of Bursa. Micromorphologica l, palynological and anatomical properties were examined with SEM (Scanning Electron Microscope) and LM Light Microscope According to micromorphological examinations, Verbascum stenostachyum has dense stellate and rare glandular hairs. In anatomical exa minations, single row epidermis cells in the stem, leaf cross sections, and anomocytic type stomata are at the same level as the epidermis cells. Idioblast cells of different sizes containing druse crystals were found under the epidermis cells. The pollen shape was determined to be prolate spheroidal, and the pollen to be tricolpate. The pollen ornamentation was determined as reticulate. The seeds have different shapes, such as prismatic, oblong, and ovate and are dark brown black. Surface ornamentation was determined as reticulate.
