Histological techniques were employed in order to analyse the secretory structures, namely translucent glands (secretory cavities), black glands, and type B secretory canals (secretory ducts) in the flower elements of four species of the Hypericum genera from Bihor County. In the Romanian Pharmacopoeia 10th edition (1993) only the H. perforatum species L. is mentioned as a source for Hyperici herba [14]. However, for the medicinal use it is possible to harvest other species from the spontaneous flora found in hill and mountain areas. These histological characters could constitute criteria for identifying possible substitutions.
