杜鹃花科鹿蹄草属的分类修订

鹿蹄草属（Pyrola L.）植物属杜鹃花科水晶兰亚科，是北温带针叶林和针阔混交林下重要的地表植被，且为森林系统健康与否的标志之一。该属植物的研究历史可追溯到林奈时期，但因物种分布范围广，分类鉴定困难，世界范围内的全面而深入的分类修订工作并未完成。本项目拟在前人工作的基础上，通过适度补充野外调查、深入核查馆藏标本以及研究各个物种名称发表的原始文献和材料，以宏观形态特征为主，结合野外居群生活习性和生境特征等方面的调查，加上必要的显微形态及多学科研究手段，查清鹿蹄草属植物的物种多样性，比较分析各个形态学性状和变异式样并评价各性状的分类学价值，探讨属下类群间的系统关系，完成该属的分类修订工作。

Pyrola L. (Monotropoideae, Ericaceae), is found in patches in the understories of temperate coniferous or sometimes deciduous forests in the Northern Hemisphere and is one of the indicators of the health of the forest ecosystem. Its taxonomical history can be dated back to Linnean period, but for its wide distribution and difficulty in species identification, a comprehensive and in-depth taxonomy has not yet been finished. On the basis of previous works, multidisciplinary research methods including moderate field population observation, deeply verification of.herbarium materials and original references, and necessary microscopic morphology investigation, to clarify the plant diversity for the genus Pyrola. At the same time, this project will compare the traditional traits and assess their taxonomic values, and then explore infrageneric relationships and complete its taxonomic works.
