Chinese Red Pine - Description

Description

Pinus tabuliformis is a medium-sized evergreen tree 20–30 m tall, with a flat-topped crown when mature (whence the scientific name, 'table-shaped'). The growth rate is fast when young, but slows with age. The grey-brown bark fissures at an early age compared to other trees. The broadly spreading shape is very pronounced, in part due to the long horizontal branching pattern.

The needle-like leaves are shiny grey-green, 10–17 cm long and 1.5 mm broad, usually in pairs but occasionally in threes at the tips of strong shoots on young trees. The cones are green, ripening brown about 20 months after pollination, broad ovoid, 4–6 cm long, with broad scales, each scale with a small prickle. The seeds are 6–7 mm long with a 15–20 mm wing, and are wind-dispersed.

Varieties

There are two varieties:

  • Pinus tabuliformis var. tabuliformis. China, except for Liaoning. Broadest cone scales under 15 mm broad.
  • Pinus tabuliformis var. mukdensis. Liaoning, North Korea. Broadest cone scales over 15 mm broad.

Some botanists also treat the closely related Henry's Pine (Pinus henryi) and Sikang Pine (Pinus densata) as varieties of Chinese Red Pine; in some older texts even the very distinct Yunnan Pine (Pinus yunnanensis) is included as a variety.

Famous quotes containing the word description:

    An intentional object is given by a word or a phrase which gives a description under which.
    Gertrude Elizabeth Margaret Anscombe (b. 1919)

    The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.
    Freda Adler (b. 1934)

    The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.
    George Gordon Noel Byron (1788–1824)
