Leaf Morphology
Leaf Type
Specialized needle-like leaves, evergreen
Shape
Linear, needle-like, clustered in fascicles typically of three
Margin
Entire, finely serrulate (minutely toothed along margins under close inspection)
Arrangement
Spiral on twigs, grouped into fascicles (bundles) bound by a persistent basal sheath
Venation
Parallel (single vascular bundle running centrally through each needle)

Description
The Loblolly Pine is a major timber tree featuring a straight, tall trunk, deeply furrowed scaly reddish-brown bark, and a dense, rounded crown. Its distinctive long needles grow in bundles of three and create a soft, rust-colored carpet on the forest floor as they drop.
Habitat
Found primarily in lowlands, coastal plains, old fields, and poorly drained flatwoods, thriving in acidic, nutrient-poor clay or sandy loam soils with high moisture and full sun exposure
Native Range
Native to the southeastern United States, ranging from southern New Jersey south to central Florida and west to eastern Texas
