††† World level: NE
††† Black Sea Regional level: NE

Distribution:

Habitats type, Critical habitats, Limiting factors: Coastal sands and shingles. Critical habitats: Sevastopol and Evpatoria areas and Tarkhankut Cape (the only localities in the Crimea). Limiting factors: probably, the low level of competition ability in coastal plant communities and the stenotopic nature of the species.

Biology: Bloom - from May to June; fruitage - from July to August; a deep tap root system; propagation - by seed and vegetatively (by long rhizomes). The species is a euxerophyte and halophyte.

Population trends: The species is declining in abundance.

Threats: The re-making of the coast into a resort zone.

Conservation measures taken: Special measures are absent as a whole.

Conservation measures proposed: The species needs to be monitored in the Black Sea region; the creation of Tarkhankut natural reservation.
