Cupressus dupreziana, commonly known as the Saharan Cypress or Tarout, is native to the mountains in the Central Sahara Desert. It has formed a unique population of trees which are hundreds of kilometers from other trees, of which there are only 233. Cupressus dupreziana is critically Endangered according to IUCN Red List of Threatened Species. It is considered to be one of the world’s 12 rarest tree.

The etymological root of the binomial name Cupressus is derived from the old Latin name for ‘Italian cypress’. Dupreziana is named after Captain Duprez, a commander of the French forces in the Djanet oasis at Fort Charlet and discoverer of this tree.

Although the distribution of this tree at present is extremely limited the landscape architect may find Cupressus dupreziana useful as an upright conifer tree similar to Cupressus sempervirens. Once established this tree is drought tolerant.
