The Orchid Genera Anacamptis, Orchis and Neotinea

More about the book

This complex work on Orchid Genera presents an updated classification of 36 species and 38 subspecies, reflecting recent advancements in molecular biology that have clarified plant relationships. Notably, two groups previously classified under Orchis are now reallocated to Anacamptis or Neotinea, while only one species from Aceras is integrated into Orchis. The authors provide a thorough analysis of these Eurasian orchids, reorganizing them based on phylogenetic concepts, morphological, and chorological traits, culminating in a comprehensive monograph of the three genera. The nomenclature has been adjusted to reflect these relationships, resulting in the recombination of certain taxa. The book includes keys for identifying genera, species, and subspecies, along with detailed descriptions of each taxon, their variability, ecology, biology, distribution, and conservation status. Initial chapters cover the exploration history of Orchis and the new methodologies employed in this research. It features previously unseen details of vegetative and generative phases, flower structures, SEM images of pollinaria and seeds, and habitat photographs. For the first time, all hybrids of these genera are documented with descriptions and images. This work serves as an essential resource for botanists and orchid enthusiasts, enhancing their understanding of this intricate group.
