56. PINUS PUNGENS
- 1803 P. taeda Lambert, Gen. Pin. i. t. 16, (as to cone). (not Linnaeus).
- 1806 P. pungens Lambert in Ann. Bot. ii. 198.
- 1852 P. montana Noll, Bot. Class Book, 340. (not Miller).
Spring-shoots multinodal. Leaves binate or ternate, from 3 to 7 cm. long; resin-ducts medial, or with an occasional internal duct, hypoderm biform. Scales of the conelet much prolonged into a very acute triangle. Cones from 5 to 9 cm. long, symmetrical or subsymmetrical, tenaciously persistent, serotinous; apophyses lustrous or sublustrous fulvous brown, much elevated along a transverse keel, the umbo forming a stout formidable spine, uniform or nearly uniform on all faces of the cone.
A mountain species ranging from central Pennsylvania to northern Georgia, with isolated stations in western New Jersey and Maryland. It is remarkable among the Pines of eastern North America for the size and strength of the spines of its cone. The armature resembles that of the cone of the western P. muricata, but with the difference that the western cone is strongly oblique, the anterior and posterior spines varying greatly in size.
