Amongst forest and ornamen-tal trees and shrubs, members of the Conifer family hold a deservedly high place. Many of them, like the Silver Firs (Abies) and the Spruce Firs (Picea), the Larches, Pines, and Firs, are valuable timber trees, and are raised in hundreds of thousands annually in several nurseries in the United Kingdom, and are disposed of when two to three years of age. For the purposes of the re-afforestation of our waste lands many kinds of conifers might be very largely planted in addition to Oaks, Beeches, Ashes, Birches, Sweet Chestnuts, and many others dealt with in the preceding pages. With the exception of the Larches, the Maidenhair Tree (Ginkgo biloba), the Deciduous Cypress (Taxo-dium distichum), most conifers are evergreen.
