“DIVISION GNETOPHYTA”
The three genera of the gnetophytes are highly specialized to their respective environments, making it difficult to identify homologous characters.[5] The three extant genera of gnetophytes, a “bizarre and enigmatic” trio,[2] are likely aberrant members of the group, which was diverse and dominant in the Tertiary.[5] Some synapomorphies of the gnetophytes include enveloping bracts around the ovules and microsporangia, and a micropylar projection of the outer membrane of the ovule that produces a pollination droplet.[6]
Gnetum species are mostly woody climbers in tropical forests. However, the most well-known member of this group, Gnetum gnemon, is a tree. Its seeds are used to produce a crispy krupuk snack known as
