''Phyllocladus trichomanoides'' (Tanekaha) is a coniferous tree native to New Zealand. Tanekaha is a medium-sized forest tree growing up to 20 m in height and 1 m trunk diameter. The main structural shoots are green for 2–3 years, then turn brown as the bark thickens. The leaves are sparse, tiny, scale-like, 2–3 mm long, and only green (photosynthetic) for a short time, soon turning brown. Most photosynthesis is performed by highly modified, leaf-like short shoots called ''phylloclades''; these are arranged alternately, 10-15 on a shoot, the individual phylloclades rhombic, 1.5-2.5 cm long. The seed cones are berry-like, with a fleshy white aril surrounding but not fully enclosing the single seed. ==Economic uses== Like the Kauri, Tanekaha shed their lower branches, producing smooth straight trunks and knot-free timber which is sought after for its strength. The bark is rich in tannin, from which Māori extracted a red dye. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phyllocladus trichomanoides」の詳細全文を読む スポンサード リンク
