Pinus ponderosa, commonly known as the ponderosa pine, [3] bull pine, blackjack pine, [4] western yellow-pine, [5] or filipinus pine, [6] is a very large pine tree species of variable habitat native to mountainous regions of western North America.

Pinus dalatensis is a medium-sized evergreen tree growing to 30 to 40 metres (98 to 131 ft) tall. It is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath. The needles are finely serrated, and (3-)5–14 cm long.
Pines in this subgenus have one to five needles per fascicle and one fibrovascular bundle per needle, and the fascicle sheaths are deciduous, except in P. nelsonii, where they are persistent. Cone scales are thinner and more flexible than those of subgenus Pinus , except in some species like P. maximartinezii , and cones usually open soon after ...
Western white pine is a large tree, regularly growing to 30–50 metres (98–164 ft) tall.
