The wall flora of the Nebet Tepe Architectural Reserve in the city of Plovdiv (Bulgaria)

Abstract

The flora of the Nebet Tepe Architectural Reserve in the city of Plovdiv (Thracian Plain) was studied in the period 1998–2003. The number of plants growing spontaneously on and around the fragments of the fortification wall and on the pavements is 131. The flora is analyzed with respect to the local distribution of the taxa, their chorology, life form and geoelement characteristics. The flora contains a relatively high proportion of ruderals and weeds. The hemicryptophytes and therophytes constitute the largest group. The following families are distinguished by the greatest number of species: Asteraceae (14), Fabaceae (13), Poaceae (12), Brassicaceae (8), Scrophulariaceae (7), Caryophyllaceae (7). The species Cerastium tauricum Spreng. and Melica transsilvanica Schur are recorded for the first time for the flora of the Thracian Plain floristic region. The results are compared with other European and Mediterranean wall floras
