The main objective of the proposed research is to complete biosystematic and nomenclatural studies needed for a monograph of the entire goldenrod genus Solidago (Compositae: Astereae). As well, long term research on asters will continue. Solidago includes more than 100 species distributed in North and South America and across Eurasia with several native North America species now being dominant invasive plants in Europe and eastern Asia. The applicant has worked on Solidago for four decades and has seen most N.A. species in the field and cultivated others from South America and Eurasia. Collaboration with researchers on a DNA based phylogeny will continue. Cytogeographic and multivariate morphometric analyses of all groups within the genus are nearly complete. During the past five years over 2000 specimens were scored for morphogy studies done to resolve species limits and to expand work done for the treatments of the genus by the applicant for Flora North American and the English language version of the Flora of China and to resolve problems noted in the books. Dozens of manuscripts on cytogeography and morphological analyses of species groups within the genus will be submitted for publication. Visits to large herbaria across Canada, in Europe and in the U.S. are needed to create detailed distribution maps and resolve nomenclature problems. The applicant has acquired a rare, very high level of knowledge on these sometimes common and widely distributed, sometimes very rare and narrowly distributed plant species that make up important parts of floral communities in the summer and fall over much of the multi-continent distribution of the genus. Turning this knowledge into a detailed, richly illustrated monograph of the entire genus has been a long term goal. Completion of the monograph ensures that this knowledge is set down in the most useful format for transfer to ecologists, naturalists and the general public: a book with descriptions, distribution maps, line drawing illustrations, and detailed discussions of each kind of goldenrod that will facilitate identification of members of a genus widely acknowledged to be a one of the most taxonomically challenging genera of flowering plants.

本研究的主要目的是完成一枝黄花属（菊科：紫菀属）的生物系统学和命名学研究。此外，对紫菀的长期研究将继续下去。一枝黄花包括100多个物种，分布在北美和南美以及欧亚大陆，其中几个北美本土物种现在是欧洲和东亚的主要入侵植物。申请人在一枝黄花上工作了四十年，见过大多数的N.A.在田野里的种和来自南美洲和欧亚大陆的栽培的其它的。 与研究人员在基于DNA的遗传学方面的合作将继续下去。细胞地理学和多变量形态分析的所有组内属已接近完成。在过去的五年中，对2000多个标本进行了形态学研究，以解决物种限制问题，并扩大申请人在北美植物群和中国植物群英文版中对该属的处理工作，并解决书中指出的问题。 将提交数十份关于该属内物种群的细胞地理学和形态学分析的手稿供出版。需要访问加拿大，欧洲和美国的大型标本馆，以创建详细的分布图并解决命名问题。申请人已经获得了关于这些有时常见且广泛分布、有时非常罕见且分布狭窄的植物物种的罕见的、非常高水平的知识，这些植物物种在该属的多大陆分布的大部分地区构成夏季和秋季的花群落的重要部分。把这些知识变成一个详细的，说明丰富的专着，整个属一直是一个长期的目标。 专著的完成确保了这些知识以最有用的格式被记录下来，以便转移给生态学家，博物学家和公众：一本书，其中包括描述，分布图，线条图插图，以及对每种黄花的详细讨论，这将有助于识别一个被广泛认为是开花植物中最具挑战性的分类属之一的成员。
