Pinus echinata Mill.

Pinus echinata Mill.. The shortleaf pine or Pinus echinata is a species of coniferous tree endemic to the United States. The shortleaf pine is sometimes referred to as the "old field", "spruce", "rosemary", "yellow", "two-leaf" and "heart" pine. The common name "shortleaf pine" may refer to other species like loblolly pine, based on a custom in the Southeastern United States to only refer to pines as either "long-leaf" or "short-leaf". However, P. echinata can be distinguished from other pines by examining its short leaves and small cones.
