Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (/ pɪˈnɒfɪtə, ˈpaɪnoʊfaɪtə /), also known as Coniferophyta (/ ˌkɒnɪfəˈrɒfɪtə, - oʊfaɪtə /) or Coniferae. The division contains a single extant class, Pinopsida.
Conifers are the most species-rich lineage of gymnosperms. From the fossil record, we think there were over 20,000 species of conifers. However, their diversity declined with the dinosaurs.
Typical examples of conifers include cedars, cypresses, firs, junipers, pines, redwoods, spruces, and yews. Conifers can be found growing naturally in almost all parts of the world, and are frequently dominant plants in their habitats.
