Threats. Human activities, mainly the changes in the land use regimes and hydrological regime in the locality, had negative impact on the habitat and caused the extinction of the species from the Bulgarian flora.
Conservation measures taken. Protected species according to the national Biodiversity Act.
Conservation measures needed. Thorough exploration of the region of the former occurrence for possible re-discovery of the species; research for re-introduction of the species from another European population.
Note. The species was reported by Velenovský (1898) based on material collected by V. Stribrny in 1896 near Manole village, Plovdiv district (SOA 15574 !). Afterwards the species has not been seen again. The Bulgarian locality is the only locality on the Balkan Peninsula. It is assumed that the species became extinct due to human activities in the region and changes of the ecological conditions in the locality. Re-discovery of the species is possible (Ančev 2001).
