Pinus jeffreyi A.Murr.

Jeffrey Pine

An open, conical-columnar tree 20-30 m tall with short, horizontal erect-tipped branches. Bark brown to blackish and fissured into plates. Buds non-resinous with free scale tips. Young shoots waxy blue-violet. Leaves in 3's, 16-25 cm long, thick, flexible, crimped, grey-green, lemon-scented when crushed. Cones ovoid-oblong, solitary, 12-20 cm long, 8-12 cm wide, scale tips with small recurved prickles. Seed about 1 cm long with wing 2-3 cm long.

Grows naturally in a range of soils in mostly montane coniferous forest areas at altitude 1500-3000 m and often replacing P. ponderosa at high elevations. Rare in cultivation in Australia.

W USA (California).

Similar to P. ponderosa but with darker bark, jigsaw pattern in detail similar to P. ponderosa; crushed stems variously described as smelling of lemon, vanilla, butterscotch or pineapple (but not like turpentine as in P. ponderosa), buds non-resinous with free scales, more waxy foliage, and larger cones with the prickles mostly curving inwards. Trees without cones resemble P. coulteri but the crown is narrower and the leaves usually shorter.
