Pinus parviflora, also known as five-needle pine, [2] or Japanese white pine, [2] is a pine in the white pine group, Pinus subgenus Strobus, native to Japan.. It is a coniferous evergreen tree, growing to 15–25 m in height and is usually as broad as it is tall, forming a wide, dense, conical crown.
Pinus morrisonicola (Taiwan white pine; Chinese: 台灣五葉松; pinyin: taiwan wuyesong; lit. 'Taiwan five-leave pine'), is a species of conifer in the family Pinaceae. It is a large tree, up to 15–25 m (50–80 ft) high and 1.2 m (4 ft) in diameter. The trunk is often crooked. Needles are in bundles of five.
Pines with one fibrovascular bundle per leaf, (the former subgenera Strobus and Ducampopinus) were known as haploxylon pines, while pines with two fibrovascular bundles per leaf, (subgenus Pinus) were called diploxylon pines. Diploxylon pines tend to have harder timber and a larger amount of resin than the haploxylon pines.
The common name "shortleaf pine" may refer to other species like loblolly pine (Pinus taeda), based on a custom in the Southeastern United States to only refer to pines as either "long-leaf" or "short-leaf". However, P. echinata can be distinguished from other pines by examining its short leaves and small cones. [2]
Pinus albicaulis leaves are in fascicles (bundles) of five, and the cone is dark purple when immature (Mount Rainier National Park). Whitebark pine is a member of the white pine group, the Pinus subgenus Strobus, and the section Strobus; like all members of this group, the leaves (needles) are in fascicles (bundles) of five [5] with a deciduous sheath.
Western white pine is a large tree, regularly growing to 30–50 metres (98–164 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, [5] with a deciduous sheath.
Pines have four types of leaf: Seed leaves on seedlings are borne in a whorl of 4–24. Juvenile leaves, which follow immediately on seedlings and young plants, are 2–6 centimetres (3 ⁄ 4 – 2 + 1 ⁄ 4 inches) long, single, green or often blue-green, and arranged spirally on the shoot. These are produced for six months to five years ...
Like most members of the white pine group, Pinus subgenus Strobus, the leaves ("needles") are coniferous, occurring in fascicles (bundles) of five, or rarely three or four, with a deciduous sheath. The leaves are flexible, bluish-green, finely serrated , and 5–13 cm (2–5 in) long.
