%X Within the species Casuarina littoralis there are diploid and tetraploid forms, having 22 and 44 chromosomes respectively. Previous records of 2n = 48 are erroneous. The tetraploid form has an almost continuous distribution in eastern Australia and Tasmania, whilst the diploid has a small, distinct distribution in New South Wales and Queensland. Under certain conditions hybridization has oocurred.
