Systematic study on plant diversity in southern East Asia

1998年在马来西亚和海南的基纳巴卢山和卡梅隆高地，中国，以及在泰国半岛和马来西亚的基纳巴卢山和卡梅隆高地，在1999财政年度的不同季节进行了实地工作。植物区系研究主要集中在膜叶科和忍冬科，并利用分子指示剂，特别是rbcL，对一些复杂的物种组进行了分类研究。这些野外工作中采集的标本保存在主要的植物标本库中，并向任何系统的植物学家开放以供进一步分析。Iwatsuki对皇家植物园的标本库、巴黎国家自然历史博物馆、莱顿的Rijksherbum和密歇根大学的密歇根大学标本馆进行了标本库工作，以进行金莲科的植物区系调查，并在Kew的Rolyao植物园进行了标本库工作，以进行忍冬科植物区系的研究。他们的研究结果将分别发表在《泰国植物志》和《泰国植物志》上。

Field works were carried on in Mt Kinabalu and Cameron Highlands in Malaysia and Hainan, China in 1998, and in Peninsular Thailand and Mt Kinabalu and Cameron Highlands in Malaysia in a different season in 1999 fiscal year. Focus was on Hymenophyllaceae and Caprifoliaceae for floristic studies, and a-taxonomy of some complicated species groups were studied by using molecular indicator, especially rbcL. Herbarium specimens collected in these field works are preserved in major herbaria and open to any systematic botanists for further analysis.Herbarium works were carried on in the herbaria of Royal Botanic Gardens, Kew, Museum national de Histoire naturelle, Paris, Rijksherbarium, Leiden, and University Herbarium, University of Michigan by Iwatsuki for floristic survey on the Hymenophyllaceae, and in Rolyao Botanic Gardens, Kew, by Fukuoka for floristic study on the Caprifoliaceae. Their results will be published in Flora Malesiana and Flora of Thailand, respectively.
