Division Gnetophyta

 Gnetophyta are cone-bearing,
low - lying plants.The cones, unlike
coniferophyta, do not have sticky resin. 
These are male and female cones
on the same plant. The seeds
    have stored food cotyledon.  

Welwitschia Mirabilis - Only ever grows two leaves which just keep growing and can live for between 400-1500 years old! Believed to date from Jurassic period

 The seeds are not covered by a testa 
which is the protective coat that the 
seeds on angiospermophyta have.
