Pinus heldreichii var. leucodermis
Native to (or naturalized in) Oregon:
- Conifer, evergreen tree, slow growing, may reach 70 ft (20 m) tall, pyramidal habit. Bark gray, leaving yellow to whitish patches after exfoliating in irregular scales. Young shoots gray-white, thick and glabrous (hairless), appearing like a snakeskin after the needles fall (Krüssmann, 1985) (Sometimes called the "snakeskin pine".) Needles 2 per bundle, very densely arranged, forward pointing, 7-9 cm long, stiff, dark green, stomatal lines on all sides, sheath 10-12 mm long. Cones oblong-ovate, cobalt-blue or black when young, 5-7.5 cm long, short stalked, brown.
- Hardy to USDA Zone 6 Native to the Balkans. Common ornamental pine in Europe.
- Taxonomy: This species was first described as Pinus heldreichii, to honor Theodor von Heldreich, by botanist K. Hermann Christ in 1863 from a sample collected on Mount Olympus. In 1864 it was described a second time as Pinus leucodermis by botanist F. Antoine who was unaware of the earlier publication by Christ. For some time the two taxa were maintained as separate, but modern studies show that both names refer to the same taxon. The first description was as Pinus heldreichii and hence it is the accepted name.
