GENUS INDEX

GENUS CODE: PINUS
GENUS SCIENTIFIC: Pinus
GENUS AUTHORITY: L.
GENUS COMMON: Pine
GENUS SUMMARY: A genus of about 110 species, trees, of the Northern Hemisphere, south to Central America. The State Tree of North Carolina is the “Pine,” the species left (artfully and politically?) ambiguous.
GENUS IDENTIFICATION: Identification notes: Young saplings generally have shorter needles than larger saplings and mature trees; measurements in the key are those of mature trees. Seedlings have needles single, rather than fascicled. “Cones” in the key below refers to mature (brown) female cones.

SCIENTIFIC NAME: Pinus taeda
COMMON NAME: Loblolly Pine, Old Field Pine
SYNONYMY: [= Ar, C, F, FNA, G, Il, K, RAB, S, Tn, Va, W, WH3, Z]
PHENOLOGY: Mar-Apr; Oct-Nov.
HABITAT: Forests, fields, pine plantations, much more abundant and widespread than formerly, occurring farther west than as a native.
COMMENTS: Native from s. NJ, DE, and e. MD south to n. peninsular FL, west to e. TX and se. OK, primarily on the Coastal Plain, but inland to s. TN; this distribution now expanded by forestry plantation northward. See P. elliottii for additional characters to distinguish these two species.
