	Cupressus dupreziana - Wikipedia, the free encyclopedia
		Cupressus dupreziana, the Saharan Cypress, is a very rare coniferous tree native to the Tassili n'Ajjer mountains in the central Sahara Desert, southeast Algeria, where it forms a unique population of trees hundreds of kilometres from any other trees.
		This species is distinct from the allied Cupressus sempervirens (Mediterranean Cypress) in its much bluer foliage with a white resin spot on each leaf, the smaller shoots often being flattened in a single plane.
		Stewart, P.J. Cupressus dupreziana, threatened conifer of the Sahara.

	Cupressus - Wikipedia, the free encyclopedia
		The genus Cupressus is one of several genera within the family Cupressaceae that have the common name cypress; for the others, see cypress (disambiguation).
		As currently treated, these cypresses are native to scattered localities in mainly warm temperate regions in the northern hemisphere, including western North America, Central America, north-west Africa, the Middle East, the Himalaya, southern China and north Vietnam.
		Cupressus sempervirens is the type species of the genus, defining the name Cupressus.

		The hybrids Cupressus sempervirens (as female) x C. dupreziana (as male) aroused great interest, becuase some morphological traits of hybrids were always identical to those of the paternal tree, C. dupreziana.
		dupreziana is native to the Tassili N’Ajjer (figure 1) desert of Algeria and is one of the most threatened trees in the world.
		In this variant, viable pollen (male gametophyte) is diploid, embryos do not have the same allozymes as their mothers, and the endosperm (seed nutritive tissue) is not haploid, although in Gymnosperms it is derived solely from the female gametophyte.

		The Genus Cupressus is one of four within the Family Cupressaceae that have the common name cypress - the others being the superficially similar Chamaecyparis, and the rather less similar Taxodium and Glyptostrobus.
		The number of species recognised within this genus varies sharply, from 12 to 24 according to the authority followed.
		Cupressus species are found in warm temperate regions in the northern hemisphere, such as western North American and Central America, north-west Africa, the Middle East, Himalayan regions, southern China and north Vietnam.

		The North African cypress is found in the wild only in Algeria, on the Edeni plateau of the central Sahara.
		However, efforts began in 1987 to sustain and reintroduce this beautiful cypress in its native habitat.

		The most notable palaeo-endemic relict Saharan-Mediterranean flora tree species are cypress "tarout" Cupressus dupreziana, of which there are about 240 specimen left in the world, wild olive Olea laperrini and myrtle Myrtus nivellei (Barry et al., 1970).
		Cupressus dupreziana is one of 12 critically endangered plants selected by IUCN's Species Survival Commission to highlight the serious threats to species around the world (Dobr, 1988).
		Due to the changing climatic conditions, species such as Cupressus dupreziana are incapable of reproducing in their natural surroundings and will eventually become extinct unless conservation measures succeed.

		A paleoclimatic record for the Late Holocene in the Central Sahara: tree rings of Cupressus dupreziana from the Wadi Tanezzuft area (SW Fezzan, Libya)
		Information about precipitation changes and hydrological oscillations were obtained through a dendrochronological study of Cupressus dupreziana Camus, used to make house doors in the old cities of Ghat and Barkat, Libya, and imported from the Tassili massif (basin of the Wadi Tanezzuft).
		dupreziana is not highly suitable for crossdating, however, it may be a source of palaeoclimatic information.

		Trees of the species Cupressus dupreziana, one of the 12 rarest in the world and occurring only in a region of the Sahara Desert - Tassili N'Ajjer, in Algeria, number only 231 individuals living in a natural environment.
		The pollen of Cupressus dupreziana lodges in the female sexual organ of Cupressus sempervirens, and generates an embryo there.
		This being so, the descendents should have a genetic lineage composed of genes from the male parent (the rare cypress) and the female parent (the more common variety), but the genetic characteristics of the embryos are exactly the same as those of Cupressus dupreziana.
