		The Welwitschia is endemic to the Namib desert, i.e.
		The Welwitschia is restricted to a narrow path of this desert.
		The Pforte Welwitschia is 1.2 m tall and the circumference at the base of its leafs is 8.7 m.

	Welwitschia mirabilis
		Welwitschia is clearly not wind pollinated, as it produces smaller amounts of pollen, with the nectar to attract insects, and the flowers open in succession over an extended period, which also encourages cross-pollination.
		Welwitschia is still common in its habitat and shows variability, which is a sign that it is far from extinction.
		Welwitschia is thought to be a relic from the Jurassic period when gymnosperms dominated the world's flora, its ancestor trapped in an environment that slowly but progressively became more arid, and all its close relatives long since disappeared.

		Welwitschia leaves grow at the rate of about five inches per year throughout the life of the plant, arcing out from the thick woody stem onto the desert floor, where the tips are roasted.
		Welwitschia is found only in a fairly narrow strip of land extending from central Namibia to southern Angola.
		The secret of Welwitschia's survival is that it absorbs fog droplets through millions of tiny pores on both surfaces of its leaves, and closes the pores at about 10 a.m., when the fog burns off.

		While welwitschias are classified with cycads and pines as cone-bearing plants, they are at the same time thought to represent a link to flowering plants.
		This Welwitschia is a plant of remarkably bizarre habits and survives in very harsh localities where the annual rainfall is often less that 25 mm and where the coastal fog is equivalent to about further 50 mm.
		The Welwitschia's oldest living specimens are estimated at 1500 to 2000 years is capable of surviving severe conditions of stress.

	Welwitschia
		Welwitschia is a very odd genus of plants native to southwestern Africa, and containing only one species:
		Welwitschia is the only genus of the family Welwitschiacae, in the order Gnetales, in the class Gnetopsida.
		This is a desert plant which grows from a short, thick trunk, with only two leaves that continuously grow from their base, and a long, thick taproot.

		The fact that the bracts on the sterile base of the spike(s) are borne in a tight spiral of three may be significant, inasmuch as this phyllotaxis is intermediate between spiral and whorled/paired (a synapomorphy for extant Gnetales).

		He had noticed that many of the Welwitschia plants in the desert seem to be the same age.

		Its short, woody, unbranched stem is surmounted by two strap-shaped leaves that grow from a basal meristem throughout the life of the plant, becoming twisted and frayed with the passing centuries.
		The leaves contain numerous subparallel veins that may anastomose or terminate blindly in the mesophyll (this character, again, is unique in Welwitschia among the gymnosperms).
		The woody stem widens with age to become a concave disc up to a meter across, from which grow small ramified branch systems that serve only to bear pollen and seed cones (6).

		Besides the old and young Welwitschia plants in the display glasshouse, thirteen plants of old stock are growing in the Welwitschia house in the nursery (not open to the public for reasons of limited space).
		However, the lack of exact documentation of origin of the plants of the old and presumably heterogeneous stock was a major impediment for a systematic approach to such a study.
		The observations suggested that the old Welwitschia stock at Berlin-Dahlem was composed of two groups of plants, provisionally denominated as "group 1" and "group 2".
