Anatomical traits of Artemisia umbelliformis subsp. eriantha (asteraceae) alpine glacial relict from Mt. Durmitor (Montenegro)

In this study, the vegetative anatomy of Artemisia umbelliformis subsp. eriantha, a Central European alpine glacial relict, wild-growing on Mt. Durmitor (Montenegro) was examined for first time. The aim to investigate general and particular anatomical traits which might have possible taxonomic value. Microscopic slides were prepared according standard histological procedures. adventitious young root showed primary structure, while older secondary structure with well-developed periderm its surface. rhizome elements (periderm). stem cross section is characterized by round shape at certain stages, collateral vascular bundles arranged in circle. petiole concave single-layered epidermis parenchyma tissue one large two small bundles. Druses rhombohedral crystals are observed inside some cells. leaf lobe has an oblong-linear isolateral amphistomatous structure. anticlinal walls epidermal cells sinuate. Secretory canals present cortex (endodermal secretory canals) cortical parenchyma. stem, lack canals. covered T-shaped non-glandular glandular trichomes. value analyzed characteristics briefly discussed.
