gemnosperma is incorrectly written, and should be written as "Gymnosperm" being its meaning:
The correct term is Gymnosperms ( Gymnospermae ). They are vascular plants that produce seeds bare. The seeds are exposed in a little defined flower ( it is a specialized branch, which has fertile leaves called esporofilos ). A superior, or vascular plant is a plant that develops differentiated tissues, to form stems, flowers, roots, leaves, branches and fruit. They are also called Spermatophyta ( Spermatophytae ). To the gymnosperms, belong the Ginkoales, Gnetales, cycads and conifers. Simple and well known examples are the araucarias.
