Jelicote pine (Pinus patula)
Family: Pinaceae
Common names: Jelicote pine, Mexican pine, Ocote, Patula pine, Patula-den, Pinho patula, Pino, Spreading leafed pine
Distributed in: Angola, Argentina, Brazil, India, Kenya, New Zealand, South Africa, Tanzania (Africa, Latin America, Oceania and S.E. Asia)
Common uses: Boxes and crates, Cabinetmaking, Concrete formwork, Food containers, Joinery, Light construction, Paneling, Particleboard, Piling, Plywood corestock, Plywood, Posts, Pulp/Paper products, Shingles, Turnery, Vats
Product sources: Longleaf pine, Shortleaf pine (P. echinata), Loblolly pine (P. taeda), and Slash pine (P. elliottii) are so similar in structure that they are impossible to differentiate, and are usually mixed and marketed on the basis of density under the trade name Southern pine. The greatest production of Southern pine timber originates from Georgia, Alabama, Mississippi, Arkansas, and Louisiana.
