What is the chromosome number of Cactaceae cunninghamiana?
According to Merwin (1989) this species has a haploid chromosome number of x=9. Consistent with other wide-ranging species, C. cunninghamiana exhibits substantial inter- and intra- provenance variation, and therefore careful selection of the origin of planting stock is recommended.

Elfers (1988) described it as ‘the hardiest Casuarina’ found mainly in central and northern Florida.
