Calocedrus macrolepis
Calocedrus macrolepis Kurz; Family: Cupressaceae
Synonym: Libocedrus macrolepis (Kurz.) Benth
Vernacular names: Bách xanh, Pơ mu xanh, Tùng hương
Morphology: A large evergreen tree, up to 15-25 (rarely 30) metres in height, and with a diameter up to 60-80cm. Bole straight, often twisted when over 10m high. Bark dark brown with longitudinal fissures. Early branched, with big branches nearly horizontal; crown oviform. Leaves scaly, closely inserted on twigs into nodes, each node with two big leaves and two smaller opposite leaves. Female cone oval, very small, green when young, becoming violet-brown, lignified and opening into 3 fragments when mature with the middle fragment bearing 2 big winged seeds
Distribution and ecology: Recently found in Ha Tay (at Ba Vi mountain), in Lam Dong province (around Da Lat city) and in Khanh Hoa province. This species thrives well in humid climate, on yellow ferallitic soils with shallow or moderately thick, but humus-rich surface layers, occurring on close evergreen and open subtropical forests located in low or moderate high mountainous areas (over 900m asl). Good regeneration in light places, along the streams or in the edges of the forests. Seeds mature in October-December.
Uses: Wood not strong. Grains straight and texture moderately fine, resistant to termites and insects and easy to work with. Used as construction timber, for cabinet-work and for turnery. Wood is aromatic, and can be used in joss-stick making. Besides, as the tree has a beautiful crown and form, it is planted for decorative purpose. An endangered species with seriously reduced individual number and habitats, which needs strict protection in Ba Vi National Park and in Bidoup Nature Reserve.
