Etymology
The modern English name "pine" derives from Latin pinus, which some have traced to the Indo-European base *pīt- ‘resin’ (source of English pituitary). Before the 19th century, pines were often referred to as firs (from Old Norse fura, by way of Middle English firre). In some European languages, Germanic cognates of the Old Norse name are still in use for pines—in Danish fyr, in Norwegian fura/fure/furu, Swedish fura/furu, Dutch vuren, and GermanFöhre—but in modern English…
Description
Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing 3–80 m (10–260 ft) tall, with the majority of species reaching 15–45 m (50–150 ft) tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an 81.79 m (268.35 ft) tall ponderosa pine located in southern Oregon's Rogue River-Siskiyou National Forest.
Evolutionary history
Pinus is the largest genus of the Pinaceae, the pine family, which first appeared in the Jurassic period. Based on recent Transcriptome analysis, Pinus is most closely related to the genus Cathaya, which in turn is closely related to spruces. These genera, with firs and larches, form the pinoid clade of the Pinaceae. The Pinus and Cathaya lineages are thought to have diverged during the early Jurassic, very shortly after the lineage containing both diverged from the Picealineage. Th…
