This species is a north Balkan - north Pontic forest-steppe
element. It is quite frequent in southern and eastern Romania but
very rare in Transylvania where it occurs only in two known
locations - Balauseri, Mures county (discovered by E. Fulop in 1977)
and Barcut, Brasov county (discovered by Wachner in 1931 who mistook
this species forCentaurea ruthenica Lam. ). The pioneer of the
Transylvanian nature science, J. Baumgarten mentioned this plant
from Rupea (Cohalm), Brasov county at the beginning of the XIXth
century. This species is to be considered and protected in
Transylvania as a regional rare endangered species.
The populations from Transylvania are totally isolated from the
ones in rest of the whole range. Their peculiar genetic structure is
illustrated by the fact that a distinct variety occurs frequently
here, with pale flowers which seems to be absent everywhere else.
This is var. elisabetae Badarau, Groza et Pestina described
in 1996 .
