本书作者近年多次对西藏南部和东南部、云南西北部及四川西南部进行野外观察、采集实验材料；研究了国内外18个标本馆的数千份标本；对花粉形态、种皮纹饰和染色体进行系统的观察研究；对4个叶绿体基因和一个核基因进行测序并进而进行分子系统学分析。在此基础上进行了综合分析，澄清了上述两个争议的学术问题。因此可以说，本书的学术观点和结论有坚实的基础，是会令人信服的。本书在澄清党参属的范围及其与近缘类群的亲缘关系、对疑难类群依据居群观察和取样进行统计分析的基础上对党参属及其近缘类群进行了全面的分类修订。对每个物种都作了考证，给予准确而简明的描述，附以生境和分布等一系列信息，并配以精美的线条特征图和原地拍摄的、反映物种生境及生物学特性的彩色照片。Key Features Provides comprehensive descriptions and classifications of Codonopsis and allied genera Richly illustrated with line drawings and high-quality color photographs Delineates and clarifies the relationships of Codonopsis and its allied groups based on the analyses using data from external morphology, pollen morphology, chromosomes, and molecular biology Description Codonopsis and its allied genera, are a group of plants which are important in economy and horticulture. A Monograph of Codonopsis and Allied Genera (Campanulaceae s. str.) offers its audience comprehensive knowledge of these plants including palynology, cytology, population biology, morphological description, geographical distribution with vouchers cited, excellent ink illustrations, and color photos, and keys to genera and to species. This excellent work will facilitate identification of relevant plants, use of plant resources, assessment of endangered states, the development of conservation strategies, and will promote systematic and evolutionary research of this group. Readership Graduates and researchers in plant science, including botanists, horticulturists, ecologists, and pharmacologists. This book also can be used as a reference for biodiversity managers and amateur botanists.
