East Asia temperate zone and Oceania temperate zone are quite different in flora, but it was expected that the life form, especially growth pattern and wood anatomy maybe similar because of similar ecological conditions such as temperature, moisture and others. For resolving the problem of phylogenetic relationships and their diversification in similar environmental condition (temperate mesic zones), comparative anatomy of vegetative structure (wood and meristematic tissues) and DNA analysis was planned. Four field researches were conducted in northern and southern hemisphere temperate zones during this project ; east Nepal and New Zealand in 1997, Southeast China in 1998, and Australia in 1999. During those field research wood samples, DNA samples and herbarium specimens as voucher for those samples were collected ; 400 wood samples, 250 DNA samples and 8000 sheets of herbarium specimens in Nepal ; 180 wood samples, 120 DNA samples and 580 herbarium specimens in New Zealand ; 210 wood samples, 390 DNA samples and 1580.sheets of herbarium specimens in China ; and 240 wood samples, 600 DNA samples and 1200 sheets of herbarium specimens in Australia. After identification of those voucher specimens, anatomical studies and DNA analytical studies have been continued.

东亚温带地区和大洋洲温带区域的植物区域大不相同，但预计生命形式，尤其是生长模式和木材解剖结构可能相似，因为温度，水分等类似的生态状况。为了解决系统发育关系的问题及其在相似的环境条件下（温带介质区）的多样性，计划了营养结构的比较解剖结构（木材和分生组织组织）和DNA分析。在此项目期间，在北半球和南半球温带区进行了四项现场研究。 1997年东尼泊尔和新西兰东南部，1998年中国东南部，以及1999年的澳大利亚。在那些现场研究的木材样品，DNA样品和植物标本标本中，作为这些样品的代金券。尼泊尔的400个木材样品，250个DNA样品和8000张植物标本标本；新西兰的180个木材样品，120个DNA样品和580个标本室标本； 210个木材样品，390个DNA样品和1580个。以及澳大利亚的240个木材样品，600个DNA样品和1200张植物标本标本。在鉴定出这些代金券标本后，继续进行解剖研究和DNA分析研究。
