Two centres of diversity are visible: one in the Western Mediterranean (Iberian Peninsula, Morocco), and the other one in South-West Asia. Distribution maps are presented for several species from South-West Asia, which is probably the genus most important centre of diversity. A preliminary new classification of the genus Eryngium is presented, including a new combination (Eryngium subgenus Fruticosum (Wolff) Wörz stat. nov.). Both the species and the sectional diversity are conspicuously present in Turkey, where 9 of 14 sections occur. This sectional diversity decreases in an easterly direction towards Central Asia. Five Mediterranean species are much more closely related to some North American Eryngiums than to the other Old World ones. Not related to the American sections is Sect. Palmito H. Wolff, although its species bear grass-like leaves similar to some Eryngiums from South America."

Titre : Revision of Eryngium L. (Apiaceae-Saniculoideae) : General part and Palaearctic species Type de document : texte imprimé Auteurs : Arnaud Wörz, Auteur Editeur : Stuttgart : Schweizerbart Science Publishers Année de publication : 2011 Collection : Bibliotheca Botanica num. 159 Importance : 498 p. ISBN/ISSN/EAN : 978-3-510-48030-2 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Eryngium Mots-clés : monographie Résumé : "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 Eryngium 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 Eryngium (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."
