A new distribution area of angelica archangelica L. (Apiaceae) around Uludağ (Bursa) and Its micromorphological, anatomical, palynological properties

Abstract

Angelica archangelica L. is an important medicinal plant that spreads from south to north in the world. This study aims to give details on the species’ morphological, anatomical, and palynological properties, and to present the second locality of A. archangelica, which is known from a single locality in Turkey. Plant materials were collected from Bursa (Uludağ). Micromorphological properties, fruit cross-section, palynological and anatomical properties were examined with SEM and Light Microscope. In the fruit cross-section, rib oil duct, vallecular vittae, and commissural vittae were observed. The stem is covered by a single-layered epidermis. The corner collenchyma cells and secretory ducts were observed in the stem cross-section. An open collateral type of vascular system was observed in the stem, consisting of sclerenchyma cells, phloem, xylem, and vascular cambium cells. The leaf is bifacial and has a single-layered epidermis. Anomocytic stomata were located on both leaf surfaces and denser on the lower surface than on the upper surface. Hypodermis was observed under the epidermis layer. Collenchyma tissue was located between hypodermis cells. Tricolporate pollen grains were observed. Pollens are perprolate in shape. The exine ornamentation is rugulate.
