These two characters readily distinguish the major groups of pines (see Pinus classification). Pinus durangensis (Durango pine) has fascicles of 6 needles, rarely 7, and is the only species in Pinus with so many needles per fascicle. At the other extreme, Pinus monophylla has fascicles of one needle, rarely two.
Pinus durangensis is an evergreen tree reaching 25–40 metres (82–131 ft) in height, with a trunk up to 1 metre (3.3 ft) in diameter and a broad, rounded crown. The bark is thick, dark gray-brown, and scaly or fissured.
Pinus, the pines, is a genus of approximately 111 extant tree and shrub species. The genus is currently split into two subgenera: subgenus Pinus (hard pines), and subgenus Strobus (soft pines). Each of the subgenera have been further divided into sections based on chloroplast DNA sequencing [1] and whole plastid genomic analysis. [2]

The greatest number of species belong to the Pinus genus, including about 60 species and subspecies. Mexican conifers growing in subtropical climates include Pinus chiapensis, Pinus oocarpa, and Pinus tecunumanii. Mexican conifers in temperate-to-cool climates are as follow: Pinus ayacahuite; Pinus cembroides; Pinus durangensis; Pinus engelmanii
The species vary with location and conditions. Arizona pine (Pinus arizonica), Apache pine (Pinus engelmannii), and Chihuahua pine (Pinus leiophylla var. chihuahuana) are common in the northern and central portions of the range. Pinus durangensis and Pinus teocote are found from the Sierra of central Chihuahua to the southern end of the range.
