Shortleaf pine, also known as Pinus echinata, is a type of pine tree commonly found in the southeastern United States. It is known for its reddish-brown bark, slender needles, and short, scaly cones. While shortleaf pine is the most common name for this species, it can also be referred to by several other synonyms, including rosemary pine, shortstraw pine, and Arkansas pine. Other related species include loblolly pine and longleaf pine, which can also be found in similar regions. The versatile wood of the shortleaf pine makes it a valuable resource for construction, furniture, and paper production.
