Simple trichomes are present on aerial surfaces of most angiosperms and on some gymnosperms and bryophytes.
Taxonomists can now say that the ferns' closest cousins are the seed plants - angiosperms (flowering plants) and gymnosperms (such as conifers).
The known flora consists of 41 ferns and fern allies, 3 gymnosperms , 291 monocots, and 516 dicots.
Among the plant branches, there were several supported groupings representing only gymnosperms or conifers.
Moreover, since the expression pattern is similar in a gymnosperm and in an angiosperm this function appears to be evolutionarily conserved.
