Metasequoia glyptostroboides;dawn redwood

   杉科(taxo-diaceae)单种属植物,中国特产的孑遗珍贵树种。落叶大乔木,高达35米,胸径达2.5米。树皮剥落成薄片。侧生小枝对生。叶线形,柔软,羽状。雌雄同株。雄球花对生于分支的节上,集生于枝端。雌球花单生于小枝顶上。球果当年成熟。种子扁平、倒卵形,周围具翅。水杉喜光,须土层深厚、疏松、肥沃,尤喜湿润,对土壤水分不足的反应非常敏感。水杉属植物在上白垩纪广布于北美、西欧、俄罗斯西伯利亚、日本北部及中国东北地区。第三纪时分布区扩大,已知有10多种。经第四纪冰川后,全部灭绝,仅存本种,被誉为“活化石”。产于四川万县及石柱,湖北利川和湖南龙山及桑植。现中外多引种栽培。为速生造林绿化树种。水杉轻软,可供建筑、制器具及造纸等。
