is spread in the Danube plain, the Black Sea coast, North-Eastern Bulgaria
and the Tundza hilly region. The locality „Kajlaka" is the most south-western
one in the Danube plain and it is the latest known. Only one specimen grows

LJ-43; SC ( ); SO-100684,100685,100031,100032
Middle Danube Plain, near the town of Belene, on sandy coast, with fruits,
21. 10. 1999, and flowers, 3. 10. 2000.
The locality covers an area of about 2 ha. Some of the dunes have been
destroyed during excavations works, and a secondary plant community has
been formed with the following composition: Corispermum nitidum Kit,
Chenopodium botris L., Bromus tectorum L., Bryum argenteum H e d w. The
species has a very branched habitus. At the end of the year the wind picks the
stems up and carries them around which gives the place a desert-like appearance.
Although the population is stable and numerous, it is threatened because of
its isolation and significant human interference. Until now this rare species has
been found on the Black Sea coast, and in a single locality along the Danube
River, in the area of the town of Lom, with single specimens ( Й о р д а н о в ,
К у з м а н о в , 1966; К у з м а н о в , 1984). It is possible to find the plant in
other spots along the Bulgarian section of the Danube river.
