PHYTOLOGIA BALCANICA 13 (2): 153–178, Sofia, 2007 153 Catalogue of the family Brassicaceae (Cruciferae) in the flora of Bulgaria Minčo Ančev Institute of Botany, Bulgarian Academy of Sciences, Acad. Georgi Bonchev St., bl. 23, 1113 Sofia, Bulgaria, e-mail: [email protected] Received: November 09, 2006 ▷ Accepted: March 14, 2007 Abstract. The Catalogue features the taxonomic composition of family Brassicaceae in the Bulgarian flora. It presents all relevant species and subspecies with their basionyms and synonyms used in the national Floras and Keys. The taxa are accompanied by complete reference data. Given is the distribution of species by floristic regions in the country, as well as their general distribution. The Catalogue also gives the chromosome number (2n) of the species and subspecies; counts based on Bulgarian material are asterisked. All Bulgarian endemic species and subspecies are duly noted down. The synantropic species in the family account for 33.30 % and the neophytes (2.73%) are marked with a symbol. The conservationally significant taxa have been categorised and rated according to the IUCN criteria. Attached is also a list of species that were cited for Bulgaria in the different Floras, but were not confirmed in its territory. Species reported in earlier reference sources that are not encountered in Bulgaria are listed too.
