In general, this classification emphasized cone, cone scale, seed, and leaf fascicle and sheath morphology, and species in each subsection were usually recognizable by their general appearance. Pines with one fibrovascular bundle per leaf, (the former subgenera Strobus and Ducampopinus ) were known as haploxylon pines , while pines with two ...

A more recent classification divided the subfamilies and genera based on the consideration of features of ovulate cone anatomy among extant and fossil members of the family. Below is an example of how the morphology has been used to classify Pinaceae.
A pine is any conifer tree or shrub in the genus Pinus (/ ˈ p aɪ n ə s /) [2] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.. World Flora Online accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, [3] and Plants of the World Online 126 species-rank taxa (113 species and 13 nothospecies), [4] making it ...

Trees that reproduce by cloning can be considered to be much older than bristlecone pines. A colony of 47,000 quaking aspen trees (nicknamed " Pando "), covering 106 acres (43 ha) in the Fishlake National Forest in Utah , United States, has been estimated to be 80,000 years old, although tree ring samples date individual, above-ground trees at ...
Coulter pine (Pinus coulteri), or big-cone pine, is a conifer in the genus Pinus of the family Pinaceae.Coulter pine is an evergreen conifer that lives up to 100 years. [2] It is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico, occurring in mediterranean climates, where winter rains are infrequent and summers are dry with ...
They are cone-bearing seed plants with vascular tissue; all extant conifers are woody plants, the great majority being trees with just a few being shrubs. Typical examples of conifers are cedars , cypresses , douglas-firs , firs , junipers , kauris , larches , pines , redwoods , spruces , and yews .
