cone-bearing trees that are mostly evergreens and belong to the order Gymnospermae, where the seeds are present in cones or catkins.
Cone bearing trees. A Class of the Gymnospermae which includes needle-leaved trees such as pines and cypresses. Their flowers are in cones, and male and flower cones are separate. The oldest (britlecone pine) and the largest (sequoia) extant organisms belong to this Class. Their unique feature is the inheritance of cytoplasmic DNA (chloroplasts) via pollens.
Trees that usually but not always have needle leaves or scale leaves and that bear separate male and female cones. They are usually, but not always, evergreen. Some, for example, larch, are deciduous. Conifers belong to the class Gymnospermae.
