Hakea aenigma

Species of shrub in the family Proteaceae native to South Australia

Hakea aenigma, commonly known as the enigma hakea, is a critically endangered shrub in the family Proteaceae endemic to Kangaroo Island in South Australia. It is one of two Hakea species totally reliant on suckering to reproduce therefore having "reached evolutionary dead-ends" as this method of reproduction greatly limits genetic variation. The entire population of this species may be of clonal colonies descended from a single individual.
