Conifers

Seed-bearing plants are divided into two major groups: the flowering plants, or angiosperms, and a more ancient lineage, the gymnosperms. The largest and most widespread group within the gymnosperms is the conifers, which are present worldwide and play important ecological and economic roles in some regions.

Keywords: gymnosperms; plant evolution; seed plants

Figure 1. A dawn redwood (Metasequoia glyptostroboides) in autumn, showing the colour change and foliage loss typical of deciduous trees late in the growing season. Most conifers are evergreen, but some species are deciduous. The single dominant stem and overall pyramidal shape are typical of many conifers.
