Gymnosperms

Explanation:

Gymnosperms are called as naked seed bearing plants. The seeds of these plants remain naked that means they are not enclosed inside a flower. Examples include cycas, gnetophytes and Ginko. The seeds of most of the gymnosperms are enclosed in cones which are not visible until the cone attains maturity.
