Bor (drevo)

Bor (znanstveno ime Pinus) je rod iglastih dreves iz družini borovk (Pinaceae). Obstaja približno 115 vrst borov, čeprav različni avtorji dopuščajo od 105 do 125 vrst. Drevo bora ima debelo deblo in zraste v višino od 30-40 m. Je zimzelena rastlina. Uporablja se za ladijski pod in igrače. Razširjenost Bori so domorodni na večjem delu severne poloble. V Evraziji jih najdemo od Kanarskih otokov in Škotske proti vzhodu do ruskega daljnega vzhoda, in od Filipinov proti severu do nekaj nad 70° severno na Norveškem (rdeči bor) in vzhodni Sibiriji (sibirski pritlikavi bor), ter proti jugu do severne Afrike. Najdemo jih v Himalaji in v jugovzhodni Aziji, z eno vrsto (sumatrski bor) na Sumatri. V Severni Ameriki so v razponu od 66° severno v Kanadi (Pinus banksiana) do 12° severno v Nikaragvi (Pinus caribaea). Največjo raznolikost v rodu se pojavlja v Mehiki in Kaliforniji.
