DENDROLOGY

Detailed explanation-1: -Conifers are a group of trees and shrubs, for example pine trees and fir trees, that grow in cooler areas of the world. They have fruit called cones, and very thin leaves called needles which they do not normally lose in winter.

Detailed explanation-2: -Coniferous trees bear cones and have needles or scales that do not fall off. Another common name for these conifers is evergreens, although not all evergreens are actually conifers (i.e. some tropical trees and shrubs).

Detailed explanation-3: -evergreen, any plant that retains its leaves through the year and into the following growing season. Many tropical species of broad-leaved flowering plants are evergreen, but in cold-temperate and Arctic areas the evergreens commonly are cone-bearing shrubs or trees (conifers), such as pines and firs.
