Diploid chromosome numbers (2n ~ 36), reported for Romanian populations of C. banaticum subsp. banaticum, are the first evidence for diploids within this polyploid complex wi th 2x-, 4x-, 7x-, and 8x-cytotypes. The designated lectotype for the name C. grandiflorum var. banalicum (= c. banaticum) has its origin in approximate ly the same area in Romania. The Cerastium banaticum group, centred in the mountains of Italy and the Balkans, is characterised as a disjunct and evidently old assembly of taxa exhibiting morphological affinities to the C. tomentosum and C. arvense_ group.
