The Columbia ponderosa pine has long— 4 + 3 ⁄ 4 –8 in (12–20.5 cm)—and relatively flexible needles in fascicles of three. The Rocky Mountains subspecies has shorter— 3 + 1 ⁄ 2 – 5 + 3 ⁄ 4 in (9.2–14.4 cm)—and stout needles growing in scopulate (bushy, tuft-like) fascicles of two or three.
The female cones are large and usually woody, 2–60 centimetres (1–24 inches) long, with numerous spirally arranged scales, and two winged seeds on each scale. The male cones are small, 0.5–6 cm (1 ⁄ 4 – 2 + 1 ⁄ 4 in) long, and fall soon after pollination; pollen dispersal is by wind. Seed dispersal is mostly by wind, but some ...

Cupressaceae is a widely distributed conifer family, with a near-global range in all continents except for Antarctica, stretching from 70°N in arctic Norway (Juniperus communis) [3] to 55°S in southernmost Chile (Pilgerodendron uviferum), further south than any other conifer species. [4] Juniperus indica reaches 4930 m altitude in Tibet. [5]
