TY - JOUR T1 - The Anatomical Features of Endemic Hypericum spectabile Jaub. & Spach from Türkiye AU - Altınbaşak, Onur AU - Kültür, Şükran PY - 2025 DA - June DO - 10.29228/jrp.264 JF - Journal of Research in Pharmacy JO - J. Res. Pharm. PB - Marmara University WT - DergiPark SN - 2630-6344 SP - 1746 EP - 1751 VL - 26 IS - 6 LA - en AB - Hypericum L. genus is used as a soothing, antiseptic and antispasmodic agent under the name of “kantaron, kılıçotu, kanotu, yaraotu, kuzukıran, koyunkıran, binbirdelik” otu in Turkish folk medicine. This study reveals the anatomical features of H. spectabile belonging to Drosanthe sections of Hypericum L. genus. The stem, leaf and root anatomical features of the plant is investigated for the first time in this study. In the stem sections of stem there are two rows of epidermal tissue. The epidermis is surrounded by a thick cuticle layer. Just below the cortex, parenchyma covers a large area. Phloem has A type secretory secretory cells. Xylem is composed of sclerenchymatic cells and tracheary elements in vascular bundles. The pith is composed of parenchymatic cells. In the section of the root there are four-five rows of periderm. Below this tissue there is cortex parenchyma with intercellular spaces. Inward, there are phloem and xylem tissues. The pith consists of parenchymatic cells. Leaf mesophyll layer has palisade parenchyma on both surfaces. Leaf is equifacial. Collenchyma tissue is in four-five rows on the upper and lower surfaces of the middle vein. The leaf is amphistomatic. Stomata belong to anisocytic types. KW - Hypericum spectabile Jaub. & Spach KW - endemic KW - plant anatomy KW - Türkiye. CR - [1] Meseguer AS, Sanmartín I.
