Gnetales Welwitschiales Ephedrales

A plant division Gnetophyta or gnetophytes comprise trinity related families of woody plants grouped in the gymnosperms, a paraphyletic group of seed plant divisions. A gnetophytes differ from either more gymnosperms inside getting wood vessels as in the flowering plants (Angiosperms or even Magnoliophytes), & these are thought that Gnetophytes can be a class action of seed plant virtually all closely related to the flowering plants.

A Gnetophytes come divided into deuce-ace orders, from each one containing one personal & genus: Gnetales: Gnetaceae; Gnetum Welwitschiales: Welwitschiaceae; Welwitschia Ephedrales: Ephedraceae; Ephedra

A Gnetales consist of one genus, Gnetum, which are mostly woody climbers in tropical forests. Nonetheless, a virtually all easily-known member of this class action, Gnetum gnemon, occurs as tree. the seeds produced come wont to make a crisp bite called 'Keropok Belinjau' inside Malaysia and Indonesia. A Malay title for this plant is 'belinjau'.

A Welwitschiales comprise simply a single coinage, Welwitschia mirabilis. It grows exclusively in the deserts of Namibia. A plant is unknown around with simply 2 big strap-such as leaves for 100% its life. These develop day & night from either a base, and come unremarkably tattered at a stops by flutter in the winds.

A Ephedrales consist of one genus Ephedra, & come referred to as a jointfirs because it use yearn slender branches which bear midget shell-prefer leaves at their nodes. Joint fir is reputed to use at times medicative properties, however has recently been banned per FDA due to harmful and possibly fatal side results.
