作者支持将秃杉与台湾杉归并１种的观点，建议采用ＴａｉｗａｎｉａｃｒｙｐｔｏｍｅｒｉｏｉｄｅｓＨａｙａｔａ拉丁文学名和村中名称谓；根据化石和古植物地理学资料，提出杉起源于中生代晚白垩纪东亚环太平洋地区，我国东北、日本及俄罗斯西柏利亚东部地区是起源中心和早期分化中心。白垩纪末期扩散到北美，新生代早第三纪古新世扩散到中心。形成北美、欧洲两个次生分布中心。第四纪冰期后，仅在我国长江以南及缅甸北部残存，形成残遗中心；根据史料记载，杉在我国南方历史上曾有广泛分布，现代间断分布地理格局是因为长期砍伐利用而不注意保护及栽培造成的。
The author supports the view that one species of Taiwania flousiana and Taiwan should be combined with one species of sugarcane and recommends the Latin name and village name of Taiwaniacryptomerioides Hayata. Based on the fossil and paleo-phytogeographical data, it is proposed that the cedar originates from the Mesozoic Late Cretaceous East Asia Pacific, Japan and eastern Siberia, Russia are centers of origin and early differentiation centers. The late Cretaceous spread to North America, Cenozoic Era of Early Triassic spread to the center. Form North America, Europe two secondary distribution center. According to historical records, cedar was widely distributed in the history of southern China. The geographical pattern of modern intermittent distribution is due to the long-term deforestation and neglect Protection and cultivation caused.
