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.

WEAKLEY FLORA
SCIENTIFIC NAME: Pinus strobus
COMMON NAME: Eastern White Pine
SYNONYMY: [= Ar, C, F, FNA, G, Il, K, Pa, RAB, Tn, Va, W, WV, Z; = Strobus strobus (Linnaeus) Small - S; > Pinus strobus ssp. cumberlandensis J. Silba - Z; > P. strobus ssp. strobus - Z]
PHENOLOGY: Apr; Aug-Sep.
HABITAT: Moist to dry forests, bottomlands, dry, rocky ridges in humid gorges.
COMMENTS: Widespread in ne. North America, south to VA, w. and (rarely) c. NC, nw. SC, n. GA, e. TN, KY, IN, n. IL, e. IA, and MN. P. strobus was probably the tallest tree in e. North America, reaching heights of 60-70 meters. It was a very important timber tree historically. In NC a notable relict and disjunct stand of P. strobus occurs on bluffs of the Deep River in the eastern Piedmont of Chatham County; in VA P. strobus is widely but irregularly distributed in the lower Piedmont.
