Abstract

The flora of the town of Počitelj was studied in the period 2010 to 2015. The number of plants growing spontaneously on and around the remains of the fortification walls and on the pavements is 616.

(75/12.18%), Poaceae (58/9.42%), Fabaceae (48/7.79%), Lamiaceae (35/5.68%) and Brassicaceae (33/5.36%). The predominant life-forms are therophytes and hemicryptophytes with 227 and 208 taxa respectively (36.85% and 33.77%). The floral elements spectrum shows a strong prevalence of Mediterranean  plants (31.33%), while Central European plants are almost absent (0.48%). A total of 32 taxa are found on the Bosnian and Herzegovinian National Red List, while 30 taxa are classified as invasive.
