黄山松 Taiwan song [Chinese], Taiwan red pine.
Pinus taiwanensis is the Taiwanese representative of a group of three closely related taxa: Pinus taiwanensis of Taiwan, Pinus luchuensis of Japan, and Pinus hwangshanensis of mainland China. All three taxa are morphologically similar, but distinct, and they are here treated as separate species, although they could also be called subspecies of P. luchuensis.
"A large tree, up to 35 m in height and 80 cm in diameter, the trunk straight, the branches horizontal, the bark fissured into small scales. Leaves 2 in a fascicle, semicircular in cross section, more or less rigid, 8-11 cm long, the margins serrulate, generally with 4 resin ducts. Mature cones oblong-ovoid, 6-7 cm long. Seeds winged, 15-18 mm long including the wing" (Li 1975).
Liu (1970) and Li (1975) note that P. luchuensis, compared to P. taiwanensis, has longer needles (12-16 vs. 8-11 cm), fewer resin ducts (2-3 vs. 4-7); shorter cones (4-5 vs 6-7 cm); thinner bark; and different inner bark coloration (pale yellow-white vs. pale red-white).
Taiwan: Chiayi, Xinchu, Ilan, Nantou, & Taichung Xians; 750-3500 m elevation in central ranges of Taiwan; in habitats ranging from large pure stands to broadleaf-conifer forest to subalpine meadow (HAST Database, Li 1975, Liu 1970). Hardy to Zone 8 (cold hardiness limit between -12.1°C and -6.7°C) (Bannister and Neuner 2001).
An important timber tree in Taiwan (Wu and Raven 1999).
