One of the major divisions of the seed plants. The most familiar and common representatives of the division Pinophyta are the evergreen, cone-bearing trees of the order Pinales (within the class Pinopsida). Members are known colloquially as conifers. Comprising approximately 600 to 700 species, representatives of the Pinophyta are extant on all continents, except Antarctica. Because the ovules (young seeds) are exposed directly to the air at the time of pollination, members of the Pinophyta are also known as the gymnosperms; this stands in contrast to the flowering plants or angiosperms (division Magnoliophyta), which have the ovules enclosed in an ovary.
