Conifers (Coniferophyta). Conifers are the dominant phylum of gymnosperms, with the most variety of species ([link]). Most are typically tall trees that usually bear scale-like or needle-like leaves.Water evaporation from leaves is reduced by their thin shape and the thick cuticle.he layer of sporophyte tissue that surrounds the megasporangium, and later, the embryo, is called the integument. Gymnosperms were the dominant phylum in Mesozoic era. They are adapted to live where fresh water is scarce during part of the year, or in the nitrogen-poor soil of a bog.
