The Arizona Pine {''Pinus arizonica'') is a medium-sized Pine in northern Mexico , southeast Arizona , southwest New Mexico , and western Texas in the United States . It is a Tree growing to 25-35 m tall, with a trunk diameter of up 1.2 m. The needles are in bundles of 3, 4, or 5, with 5-needle fascicles being the most prevalent. This variablity may be a sign of hybridization with the closely related Ponderosa Pine (''Pinus ponderosa''). The cones are single, paired, or in whorls of three, and 5-11 cm long. It has been thought to be a variant of Ponderosa Pine by some botanists in the past, but is now recognized as a distinct species by most authorities. Two varieties are described, possibly better treated as distinct species; see Ponderosa Pine for a table of characters:
Another related pine, Cooper's Pine (''Pinus cooperi'') is also treated as a variety of Arizona Pine by some authors, as ''Pinus arizonica'' var. ''cooperi'', but other authors regard this as a distinct species, more closely related to Hartweg's Pine (''Pinus hartwegii''). This pine is a source of construction timber, and is heavily harvested for firewood. Extensive cutting has reduced the formerly widespread Arizona Pine forests, particularly in Mexico. |
