Key
270 spp., Europe, Asia, Africa and N. America. Naturalised spp. 4.
The genus includes pinks (D. plumarius, D. deltoides and various hybrids), carnations (D. caryophyllus and hybrids) and sweet William (D. barbatus). Wild N.Z. plants of D. barbatus, D. deltoides and D. plumarius have originated from selected horticultural cvs and may therefore differ slightly in some respects from the wild spp. in Europe.
