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.
- 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

Chapter 1 Introduction
The Taxonomic History and Questions to be Addressed
Abstract
This chapter describes the circumscription of Codonopsis, which has been greatly changed and is still in dispute. In addition, the systematic positions of Codonopsis and its allies in the Campanulaceae s. str. are discussed, which involves the classification system of the family as a whole and the phylogeny of the tribe Cyananteae in particular. Finally, the great controversies about the taxonomic treatments of certain species complexes are described, particularly for species related to Codonopsis convolvulacea Kurz (= Pseudocodon convolvulaceus).
KeywordsCircumscription; Codonopsis; Codonopsis convolvulacea Kurz; Systematic position; Taxonomic treatments Readers need to pay attention to three issues when reading this chapter. One is the circumscription of Codonopsis, which has been greatly changed and is still in dispute; second is the systematic position of Codonopsis and its allies in the Campanulaceae s. s., which involves the classification system of the family as a whole and the phylogeny of the tribe Cyananteae in particular, and the third is the great controversy over taxonomic treatments of certain species complexes, particularly those species related to Codonopsis convolvulacea Kurz (= Pseudocodon convolvulaceus). Discoveries in Codonopsis and Allied Genera
Wallich was the first botanist to report on Codonopsis when he established it as a new in 1824, and described three species, C. viridis, C. purpurea and C. thalictrifolia, all from the Himalaya. Roxburgh (1824) described Campanula lancifolia from what is now Bangladesh as new. The species was transferred to Cyclocodon by Kurz (1872), transferred to Campanumoea by Clarke (1881), and treated as a synonym in Codonopsis by Moeliono (1960). With the restoration of Cyclocodon Griff. ex Hook. f. & Thomson, it is now placed back in Cyclocodon (Hong & Pan, 1998). In 1825, Don described a new genus and species from Nepal, Glossocomia tenera, which was, however, the same taxon as Wallich's Codonopsis thalictrifolia. Another new genus, Campanumoea, with two new species, C. javanica Bl. and C. celebica Bl. was described by Blume (1826) from Indonesia. The status of Campanumoea, its circumscription, and its relationship with Codonopsis in particular, has been a controversial issue. Campanumoea javanica Bl. as a species has never been questioned, whereas the fate of C. celebica is quite different. It was transferred to Codonopsis by Miquel (1835), and then into Campanula by Dietrich (1839), but placed back in Codonopsis as a subspecies of Codonopsis lancifolia by Moeliono (1960). It was transferred by the present author to Cyclocodon (Hong in Hong & Pan, 1998). This action was accepted by Lammers (1998) and Morris and Lammers (1999), but they treated it again as a subspecies, Cylcocodon lancifolia subsp. celebicus (Blume) K. E. Morris & Lammers. De Candolle (1830) published two new species from India, Codonopsis parviflora Wall. ex A. DC. and Codonopsis truncata Wall. ex A. DC., based on plants discovered by Wallich. The former was transferred to Cyclocodon by Hooker and Thomson (1857), then placed in Campanumoea by <
