Genus of 5 species of evergreen shrubs and trees from open woodland and rainforest in Australia and New Guinea, valued for their panicles of flowers which give an even showier display of enlarged, brightly coloured calyces after the flowers have finished.  The genus includes Ceratopetalum gummiferum Sm., the Australian Christmas tree, much used in floristry in Australia, and C. apetalum D.Don, the Coachwood, both of which are native to the Sydney and Illawarra regions of New South Wales.  [FNSW, Beadle].  It could also be a species belonging to another genus in the family Cunoniaceae or the related Baueraceae.
