Biosystematic studies and monograph of the goldenrod genus Solidago L. (Compositae: Astereae)

本研究的主要目的是完成一枝黄花属（菊科：菊科）的生物系统和命名学研究。此外，对紫苑的长期研究将继续进行。一枝黄花有100多种，分布在南北美洲和欧亚大陆，其中一些北美本土物种现在是欧洲和东亚的主要入侵植物。申请人从事一枝黄花研究已有40年之久，在田间见过大多数单名植物，也栽培过其他来自南美和欧亚大陆的单名植物。与研究人员在基于DNA的系统发育方面的合作将继续进行。该属所有类群的细胞地理学和多变量形态计量学分析已接近完成。在过去的五年中，超过2000个标本被记入形态学研究的分数，以解决物种限制问题，并扩大该属的处理工作，由《北美植物志》和英文版《中国植物志》的申请人完成，并解决书中指出的问题。数十篇关于该属内种群的细胞地理学和形态学分析的手稿将提交出版。需要访问加拿大、欧洲和美国的大型植物标本馆，以创建详细的分布图并解决命名问题。申请人对这些有时常见和广泛分布，有时非常罕见和狭窄分布的植物物种具有罕见的，非常高的知识，这些植物物种在夏季和秋季构成了该属多大陆分布的植物群落的重要组成部分。将这些知识转化为详细的，插图丰富的整个属的专著一直是一个长期的目标。这本专著的完成确保了这些知识以最有用的形式被记录下来，以便传递给生态学家、博物学家和一般公众：一本描述、分布图、线条绘制插图和详细讨论每种黄花的书，这将有助于识别被广泛认为是开花植物中最具分类学挑战性的属之一的属的成员。

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.
