The area of central Bosnia, particularly along the flow of the rivers Bosnia and Vrbas, abounds in rare specimen of the plant kingdom. In the bluebell family (Campanulaceae) a particular place belongs to the Bosnian bluebell (Symphyandra Homfamanni), also called Hofmann’s costamen. J. Pantocsek described in its original habitant near Banja Luka and Jajce in 1881. The bluebell is a biennia, sometimes triennial plant with beet-like thickenings on its root. The stalk is straight and branching out from the bottom. Its is 20 to 50 cm high and covered with short, stiff fluff. The leaves, 5 to 10 cm long, grow alternatively closer to the bottom of the stalk. They are oval in shape, either obtuse or acute, gradually narrowing towards the broad indented leaf stem. The leaves are irregularly and roughly jagged on their edges.
