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.

东亚温带和大洋洲温带在植物群上存在较大差异，但由于温度、水分等生态条件的相似，生活型，特别是生长方式和木材解剖结构可能相似。为了解决系统发育关系和它们在相似环境条件下（温带中温带）的多样性问题，计划进行营养结构（木材和分生组织）的比较解剖和DNA分析。在该项目期间，在北方和南半球温带进行了四次实地研究：1997年在尼泊尔东部和新西兰，1998年在中国东南部，1999年在澳大利亚。在实地研究期间，收集了木材样本、DNA样本和植物标本作为这些样本的凭证;在尼泊尔收集了400份木材样本、250份DNA样本和8 000张植物标本;在新西兰收集了180份木材样本、120份DNA样本和580张植物标本;中国木材标本210份、DNA标本390份、植物标本1580张;澳大利亚木材标本240份、DNA标本600份、植物标本1200张。在鉴定了这些凭证标本之后，继续进行解剖研究和DNA分析研究。
