Revision of Eryngium L. (Apiaceae-Saniculoideae) General part and Palaearctic species

About this book

This well illustrated monograph exhaustively treats and revises the Eurasian and African species of the genus Eryngium [E:Eryngo, D:Mannstreu, F: Panicaut]. Eryngium is an annual and perennial cosmopolitan. The genus has the largest number of species (230) within the family Apiaceae.

Numerous characteristics of Erygium are considered: general morphological, chemotaxonomic and genetic characteristics, chromosome counts as well as ecological properties, distribution, fossil record and reproductive biology. Every species, every individual is part of its habitat: biological and non-biological parameters form the basis of an organism's existence by defining its evolutionary challenges. The monograph is divided into two parts.

The general part presents the general morphology and results of a cladistic analysis of Erygium (using morphology, fruit anatomy, ecological data) and compares these with genetic data. The results validate the classification of the genus into five subgenera (subgg. Eryngium, Monocotyloidea, Semiaquatica, Foetida, and Lessonia) and lead to the description of a small new subgenus, E. subg. Ilicifolia.

The special part of this revision treats 61 Eurasian and North African species in detail, providing descriptions, distribution maps, illustrations and keys for identification. Herbarium studies form the basis of this work. Phytosociological data serve as indicators for ecological requirements. An extensive list of more than 600 references, supplemented by lists of valid and illegal names rounds up this volume.
