Pinus massoniana(English:Masson's pine,Chinese red pine,horsetail pine;Chinese: Mã vĩ tùng ) is a species ofpine,native to Taiwan, a wide area of central and southern China, and northern Vietnam.

Description

[edit]
bark close-up

It is anevergreentree reaching 25–45 metres (82–148 feet) in height, with a broad, rounded crown of long branches. Thebarkis thick, grayish-brown, and scaly plated at the base of the trunk, and orange-red, thin, and flaking higher on the trunk. Theleavesare needle-like, dark green, with two per fascicle,12–20 centimetres (4+12–8 inches) long and0.8–1 millimetre (132364in) wide, the persistent fascicle sheath1.5–2 cm (5834in) long. Theconesare ovoid,4–7 cm (1+582+34in) long, chestnut-brown, opening when mature in late winter to4–6 cm (1+582+38in) broad. Theseedsare winged,4–6 mm (53214in) long with a10–15 mm (38916in) wing. Pollination occurs in mid-spring, with the cones maturing 18–20 months after.[2][3][4]

Distribution and habitat

[edit]

It is native to Taiwan, a wide area of central and southern China including Hong Kong, and northern Vietnam, growing at low to moderate altitudes, mostly below 1,500 m (4,900 ft) but rarely up to 2,000 m (6,600 ft) above sea level.[5]

Ecology

[edit]

In the 1970s and 80s, thePinewood nematodefrom North America andpine-needle scale insectfrom Taiwan, together virtually eliminated the nativePinus massonianain Hong Kong.[6]

Fossil record

[edit]

Afossilseed cone and several needles ofPinus massonianahave been described from theupper MioceneWenshan flora,Yunnan,SW China.The fossils most resemble thevarietyP. massoniana var. hainanensis,which is a tropical montanethermophilictree restricted toHainan Islandin southern China.[7]

Uses

[edit]

The species is a common tree used inplantationforestryfor replacing or compensating for the loss of the natural forest in southern China.[8]Chineserosinis obtained mainly from theturpentineofP. massonianaandslash pine(P. elliottii).

Logs are mainly used to make pulp forpaper industry.

Leaves are used to give special smoke flavor to a localblack tea,such asLapsang souchongofFujian.
