Up to last Bulgarian spring blooming bluish crocus with annulate tunics was named as "C. adamii" what of course was not true, because Crocus adamii is growing only in Caucasus mountains. Quite recently this was confirmed when group of botanists described annulate crocus from adjacent Serbia as C. randjeloviciorum. Both populations - Serbian and Bulgarian are very close - actually on both sides of border and when I compared them - turned that they are of same species. I'm offering plants collected on Bulgarian side of border.
