Gymnosperms of Alta California
California has far more gymnosperms than any other state. The state is home to 65 conifer taxa plus 4 widespread hybrid taxa. These include the largest (Sequoiadendron giganteum), tallest (Sequoia sempervirens) and oldest (Pinus longaeva) known trees. California is the center of diversity for Hesperocyparis (10 taxa, 6 endemic). It has one of the rarest firs (Abies bracteata) and spruces (Picea breweriana). There are also a remarkable 26 taxa of pines, including the largest (Pinus lambertiana), the tallest (P. ponderosa), and two of the rarest (Pinus radiata and P. torreyana) species. The state is second only to New Caledonia in conifer endemism, having 18 endemic taxa (plus one endemic hybrid taxon). Several other species are found only in immediately adjacent parts of Oregon, Nevada or Baja California Norte. California also has 7 species of Ephedra, one of which is endemic to a mountain range that straddles the CA-NV border.
